Virtualization of the Encryption Card for Trust Access in Cloud Computing

Followed by the introduction of IoT and new sustainable technologies, energy management, Quality of Service and decrease of communication costs become important and complex for enterprise systems at airports. The aviation authorities’ reports reveal that the airport ICT investments are mainly focused on travel safety, mobile commerce, and new technologies. The main idea behind a smart airport is to deploy IoT network managed through a Cloud-Fog-Edge paradigm for a smart platform and optimize the airport’s efficiency. An IoT cloud-based platform solution supports multiple types of data, advanced analytics, artificial intelligence, and machine learning techniques. However, cloud computing has certain limitations such as increased delay in data reporting, increased latency in accessing user network, limited customization, increased reliance on external network and data privacy. Fog-Cloud and Edge-Cloud paradigms can overcome the weaknesses of cloud computing architectures. Therefore, to understand the organizational impact of combining the usage of cloud, fog, and edge computing, we created an enterprise architecture that can be applied in a smart airport demonstration study. The enterprise architecture modelling was done by using ArchiMate and validated by means of an expert assessment and prototype implementation.

This paper introduces cloud computing and security situation, studies the main security problems of cloud computing, and comes up with a cloud computing security framework which can effectively solve these security problems, and points out that only to solve the security problems, cloud computing can unceasingly expanded, and the application will be more and more widely.KeywordsCloud computing securityFirewallData security

Accessing data from social networks using cloud computing has been adopted by many IT enthusiasts. It allows easy access to data and easy sending of data for communication purposes. For many social network users, cloud computing can simplify processes and save time and money. This article defines cloud computing and shows how one can quickly, safely and easily access data. It also discusses how cloud computing solutions could be beneficial to libraries in these basic areas: technology and acquisition.Today’s more libraries and social networks are joining the cloud. But despite the numerous social networks and data acquisition sites demand for data are still escalating—as they always will. To be able to access data conveniently today’s data competitiveness users of search engines must carefully scrutinize various libraries as well as social media to ensure that they match key data and communication needs and deliver intended results in the most efficient and cost-effective way. To meet these challenges, IT organizations are increasingly moving away from a device-centric view of IT, to a view that is application-, information- and people-centric. Cloud computing aligns with this new world view. Cloud computing technology is enabling IT to do more with the infrastructure that already exists, as well as adding new ways to expand capacity quickly and economically by using external cloud computing resources. This technology is enabling IT managers to treat infrastructure as a common substrate on which they can provision services to users faster in a much more flexible and cost-effective way –without having to re-design or add to the underlying infrastructure. Given the benefits of cloud computing, its broad appeal is not surprising. However, this new approach does raise some concerns. Chief among them is securing data in the cloud. This white paper will briefly review the basic fundamentals of cloud computing and describe how virtualization are enabling enterprises to move toward a flexible, federated computing model with a cohesive mix of private external and internal cloud environments. It then discusses the security implications of cloud computing and provides insights into addressing them, and offers a view of security best practices to adopt when considering cloud services.Cloud computing has become an increasingly popular means of delivering valuable, IT-enabled business services. Adopting cloud technology can be an affordable way to get access to a dynamically scalable, virtualized computing environment. Optimal IT hardware, software, expertise and infrastructure management resources that may not otherwise be available from a cost perspective can be rapidly deployed and easily scaled. Processes, applications and services can be available on demand, regard-less of the user location or device. The cloud provider is responsible for the environment, so organizations can make use of resources for short periods of time without having to maintain the environment when it is not being used. While cloud computing models are attractive because of their flexibility and cost effectiveness, certain challenges must be addressed in order to provide a viable option to traditional data services. First and foremost is the issue of security. The externalized aspect of outsourcing can make it harder to maintain data integrity and privacy, support data and service availability, demonstrate compliance, and secure highly available access to applications and information. In short, cloud computing can present an added level of risk. Organizations must therefore establish trust relationships with their cloud computing providers and understand risk in terms of how these providers implement, deploy, and manage security on their behalf. Whether delivered as part of the service or as specific components added in, your cloud provider should address the fundamentals of security and risk management through a comprehensive approach.

Cloud computing has garnered increasing attention from researchers who have presented much work on performing massive computing tasks efficiently. Many security vulnerabilities have simultaneously occurred; therefore dealing with security problems in cloud computing has become an urgent issue. The purpose of this paper is to create a cloud computing framework based on the Map Reduce platform, a Google cloud-computing platform, and solve some security problems in the process of distributed computation. Inspired by SMC (Secure Multi-Party Computation), a protocol naturally suitable for distributed computation, we adopted homomorphic encryption, which could be used for processing a large amount of data securely in cloud computation. We also find that order preserving encryption(OPE), an encryption algorithm put forward in 2004, can be used in our secure framework. Cognizant of the applicability of SMC and OPE in cloud computing, we combine them with Map Reduce to design a security framework of distributed computation. Our major contributions consist of designing an innovative cloud computation framework in security based on Map Reduce, applying the order preserving encryption(OPE) algorithm, homomorphic encryption, and constructing a real distributed computation platform.

Cloud computing is the new bending curve in the line of Information Technology and computing paradigm. Cloud computing has simultaneously revolutionized business and government sectors by stretching its arms in every possible field, from not only to Information communication technology to medical advancements to a more diverse agriculture field which was untouched by technology for a decade. Cloud computing enlightens path for another dimension of computing which is expected to rise even more than mobile computing, i.e., Internet of Things (IOT) or internet of everything. As new dimensions are being added up to the cloud domain every day this gives a window to hackers and intruders to breach the doors. The security problem is amplified under cloud computing as it introduces new problem domains. One of the major problem domain identified is data security, where security of user’s data is the utmost priority. Providing privacy to the user and the data stored by the user is to be ensured by the cloud service provider. This paper aims at the security model for cloud computing which ensures the data security and integrity of user’s data stored in the cloud using cryptography.

With the idea of new developing technologies and the rapid change in our technical environment, there is a need for smarter, more efficient technology to keep up with the needs of today's world. Thus, the idea of smart cities has come into being. The purpose of this chapter is to promote the idea of building a smart city and providing a framework for future development of the same. We are moving towards a more futuristic world where everything is connected and done over the internet, which will create more network dependency. The problem with the concept of smart cities is the need for better technologies to improve the system of data transfer to address the problem of trust in the system, as massive amounts of people's private data is at stake with bad actors trying to hack the system to gain access to it. There is also the problem of the massive amounts of data produced in smart cities, so there is a need to provide a framework to efficiently store all the data. These problems can be solved with the help of technologies such as blockchain and cloud computing. Cloud computing can be seen as a way of sharing resources offering compute, storage, databases, and network services that can be used on a larger scale. Cloud computing stores massive amounts of data, it can also be used to share and transfer data between networks in a cloud, it is cost-effective, and you can also retrieve lost data or backup data when needed. Despite cloud computing being so great, it also has its own drawbacks. The problem of security in cloud storage is ever-increasing; since cloud storage, centralized systems have been a major target for hackers and data breaches, and the data in the cloud can be tampered with and accessed by unauthorized users. If data is being transferred through the cloud it can be intercepted during transmission because of the problem of encryption. These problems can be solved as well as the system being improved and made faster with the help of blockchain. Blockchain is a database or ledger that is shared across a network. The ledger is encrypted so that only people who are authorized can access the data. Blockchain will decentralize the data stored, which will improve the security of the data immensely. If a hacker targets a single block in a node, it will not have much effect and will continue to function. Block chain works by breaking the data into smaller chunks, and the chunks are distributed in a way that even if the network is down the data will still be available. While a file is being shared it is broken into smaller pieces and sent in a way that the file transfer is quicker. The files are encrypted using a cryptographic hash table and each individual shard or part of the file is also encrypted, making the security even tighter. With the help of blockchain, the storage of files will become much cheaper and more secure. A framework is provided to manage and secure the data acquired from IoT devices through encryption using Advanced Encryption Standard (AES) algorithm and storing the data in a private or public cloud depending on the data; and then decrypting the data and sending it to the users who requested the data or for further analysis. This chapter provides a framework for a smart city storage and security model and can be used as a prototype model for future development in the field.

Cloud computing and big data: Technologies and applications

The article presents the concept and technical aspects of the development of a corporate educational information system using machine learning methods and modern approaches to ensuring information security. The proposed solution is aimed at educational institutions and provides adaptive management of the educational process, optimization of resources and increased information security. The main emphasis is on the development of the system architecture, which includes the efficient placement of servers, the use of containerization technology, system monitoring, version control, and the application of security protocols to protect data and the system as a whole. The use of two servers is proposed: one for basic computing tasks, data storage and support of basic services, and the other for backup, monitoring and protection against unauthorized access. To increase the flexibility and scalability of the system, Docker containerization technology is used, which allows isolating processes and simplifies integration with cloud services. An important component is the integration of external monitoring, which provides control over the availability of services in real time. Emphasis is also placed on the use of reinforced firewalls and backup Internet connections to increase the system's resistance to cyber threats and cyber attacks. Functionality of the system includes an intuitive interface with a number of interactive widgets, such as information about recently registered courses, uploading learning materials, an integrated calendar, displaying performance graphs and task lists. Users can quickly receive information about their progress and plan the next steps in the educational process. An important decision was to abandon the creation of our own corporate chat in favor of implementing ready-made solutions with a high level of security and support for teamwork. This allows you to significantly optimize the use of resources and focus on the development of the main functions of the system. In addition, the use of version control systems for effective project management is proposed, which allows isolating different stages of development and minimizing the risk of errors. The proposed concept of the corporate educational information system provides a comprehensive approach to the management of the educational process taking into account the requirements of modern technologies, increases the effectiveness of education and guarantees a high level of data security.

The concept of the digital divide is becoming more and more complex as access to computers and the use of computers, changes over time. When the existence of a “digital divide” first emerged, it revolved around access to computers and related technologies. The high cost of computers and related technologies creates a large divide between people who could afford them, and who had access to all the advantages of Information technology in general, and those who could not. ICT (Information and Communication Technologies) have become an indispensable tool for businesses. Competitiveness and productivity depend on them. Cloud Computing has also generated new business opportunities for companies that have understood the key to this new social and commercial space. Cloud Computing on education can bridge the knowledge divide, the resource divide and the digital divide, teachers could be empowered under the cloud warning. It can be on devices, notebook, e-book and cell-phone. Cloud Computing in order to reduce digital divide has come as a friendly way to provide computer applications to users without the need for those users to purchase, install or support software on their local computers and/or servers. This research will cover the facts and issues discovered into the Digital Divide, after exploring details and points of views from experts. Also, this research will provide two models and one framework to describe, explain and finally reduce the gap or as most of the researchers has been looking for building a bridge in order to reduce the digital divide. Since computers and, later, the Internet became popular and came to our business, there has been a different degree of acceptance thereof by the people. The variety of profiles ranging from the 'early adopter', that is one that is to last forever in this new technology, to the 'allergic' to the computer, because they do not know how to use password to login and/or prefers to work as they always have done. Is not the first time we hear about people who cannot make simples actions in a computer because their capabilities are very low. I'm talking about everyday situations, rather than more complex ones such as maintenance of machinery. This research will treat the Cloud Computing concept as a tool to Reduce Digital Divide; the digital divide will be related to issues of educational access to the benefits of digitalization and the capabilities of a group of students in three different high school centers to use ICT appropriately and contribute to sustainable development.

Cloud computing enables the on-demand delivery of resources for a multitude of services and gives the opportunity for small agile companies to compete with large industries. In the telco world, cloud computing is currently mostly used by mobile network operators (MNO) for hosting non-critical support services and selling cloud services such as applications and data storage. MNOs are investigating the use of cloud computing to deliver key telecommunication services in the access and core networks. Without this, MNOs lose the opportunities of both combining this with over-the-top (OTT) and value-added services to their fundamental service offerings and leveraging cost-effective commodity hardware. Being able to leverage cloud computing technology effectively for the telco world is the focus of mobile cloud networking (MCN). This paper presents the key results of MCN integrated project that includes its architecture advancements, prototype implementation, and evaluation. Results show the efficiency and the simplicity that a MNO can deploy and manage the complete service lifecycle of fully cloudified, composed services that combine OTT/IT- and mobile-network-based services running on commodity hardware. The extensive performance evaluation of MCN using two key proof-of-concept scenarios that compose together many services to deliver novel converged elastic, on-demand mobile-based but innovative OTT services proves the feasibility of such fully virtualized deployments. Results show that it is beneficial to extend cloud computing to telco usage and run fully cloudified mobile-network-based systems with clear advantages and new service opportunities for MNOs and end-users.

The concept of cloud computing has recently changed how hardware, software, and information are handled. However, security challenges and credibility requirements have never changed and may have increased. Protecting cloud computing and providing security for its resources and users is one of the critical challenges. As a result, most users are afraid to use their resources, because many security problems must be met. For example, authentication and reliability are major security constraints and must be provided in a cloud computing environment. There is a wide range of authentication protocols in use, but the researcher has recommended the Kerberos protocol to represent and test it in a complex environment such as a mixed cloud environment. A model has been developed to implement Kerberos authentication in a hybrid cloud computing environment to securely access the cloud computing services provided. This model is represented using the OPNET Modeler 14.5 simulation system. The network efficiency was measured before and after the hacker. Findings presented in this research are supporting the ability of the Kerberos protocol to prevent illegal access to cloud computing services, whether from within the private cloud or the public cloud. While maintaining the efficient performance of the network.

In the world of computer networking, cloud computing makes a technical shift of computing services being provided locally to being provided remotely by third party service providers. The data which was previously kept under control of users now under the control of service providers cloud computing brings many financial and functional benefits as well as serious security concerns that may threaten business continuity and corporate reputation. The definition of cloud computing is still blurry in a large part, because of the magnitude of the security risks and the virtually unlimited amount of information being published over the unsecure platform. The purpose of this paper is to assess how security risk factors are affecting the existing and prospective cloud users’ cloud usage strategies. Are they simply betting that financial benefits will surpass security risks, or are they confident that cloud providers are capable of assuring an equal or higher level of security than on-premise systems? This survey, through the examination of published materials and studies, analyzes existing issues along with available countermeasures in order to evaluate the overall assurance level of cloud security. The primary goal of the survey is to assess how security concerns have affected or will affect the respondents’ decision on adopting cloud and its services. This study includes basics of cloud computing by adding its characteristics, models and their categories. Analysis also embraced the existing security concerns faced by researchers and their imposed methodologies.

IT sector is growing day by day, its data and energy costs are also increasing, which needs to access the high-end computing capabilities. To fulfill these requirements, there is a need to shift from traditional computing practices to new computing practices that give access to a broader network, unlimited resources, and enables self-service on demand at a reasonable cost using pay per use method. All these requirements can be fulfilled with cloud computing. Cloud Computing has a number of advantages as well as disadvantages. Security is a major threat to the cloud computing because the data placed on cloud servers is always vulnerable as there are lots of attackers on the internet who tries to compromise the security of the cloud. To overcome this issue, we use security appliances in the form of physical machines or by virtualization. A significant amount of power is consumed by security appliances which not only leads to the high energy costs but also a major threat to the environment as carbon-dioxide is released. So there is a need to find optimal solutions for providing security in cloud computing environment in an efficient manner. In this paper, a comprehensive survey on existing cloud security frameworks has been done. Based upon the limitations on existing frameworks a new framework has been proposed to provide security in virtual networks that is based on Intrusion Detection and Prevention System (IDPS) and its prototype implementation has also been done.
