The emerging rapid increase in the connectivity of computer networks and their usage has drawn the attention of organizations and data science researchers towards a secure data storage architecture, where it can be protected from unauthorized entities. In this paper a novel methodology "Image Encryption with Modified Diffie Hellman" (IEMDH) is designed and developed to address the suitability of encryption algorithms for low powered de vices and to offer a better security than existing approaches to contribute towards the Intelligent Enterprise security and sustainability. Here, the symmetric AES algorithm and Modified Diffie Hellman (MDH) algorithms are combined to enhance the overall security and it also eliminates the key exchange drawback in symmetric key techniques. Later, a performance evaluation is carried out between the proposed IEMDH approach and IERSA (Image Encryption with RSA algorithm) to check the suitability on low power devices.

The Classic Diffie-Hellman (CDH) algorithm encounters several security problems. The algorithm security depends on the complexity of solving the discrete logarithm and the integer factorization problem. The security also depends on the length of bits keys used. In this paper, we proposed a hybrid algorithm, the combination of Modified Diffie Hellman (MDH) with the Rivest, Shamir, and Adelman (RSA) algorithm. The MDH will not use primitive root (g). Instead, it will use two prime numbers (P and Q) for key exchange. It reduces the possibility of a man-in-the-middle attack. Furthermore, the MDH has an authentication mechanism. If both shared keys are equal, the communication will continue. Otherwise, it will stop because it is compromised. Also, the RSA algorithm will use the two prime numbers generated by MDH (P and Q). The RSA algorithm will perform the encryption and decryption message. The Diffie Hellman (DH) and the RSA Algorithms are the basis of several security standards and services on the internet, especially TLS and SSL. If the security of both algorithms is compromised, such systems will collapse. In this proposal, the combined cryptography system aims to achieve secret message exchange; it uses random prime numbers after multiplication and eventually shared with the other end of a communication. The proposed algorithm secretly generate a value so that the security level increases

Nowadays, the development of information technology can be described as extremely rapid, especially with the widespread use of the Internet; the security of communications in the network has become an important issue we are facing. The purpose of this article is to solve the problems in today’s network security data encryption algorithms. Starting from the computer network communication security data encryption algorithm, we discuss the effects of several different encryption methods on improving network security. The research results show that it is known that the application of link encryption algorithm in network communication security encryption algorithm can increase the security index by 25%, the node encryption algorithm can increase the security index by 35%, and the end‐to‐end encryption algorithm can make the cyber activity safety index to increase by 40%. Among them, RSA algorithm and DES algorithm are two very representative algorithms; they represent different encryption systems. From the perspective of network data link, there are three methods of encryption algorithm, namely, link encryption algorithm, node encryption algorithm, and end‐to‐end encryption algorithm.

In modern edge scenarios, the security of sensor networks plays a pivotal role in ensuring the safe communication of IoT data. Therefore, deploying encryption algorithms among edge devices is of paramount importance. However, most existing research predominantly emphasizes the efficiency of data transmission while often overlooking critical aspects of data integrity and confidentiality. The communication between sensor nodes and from sensors to end nodes necessitates additional robust security measures.This paper presents an enhanced approach to the RSA and AES algorithms, tailored for deployment on low-energy IoT devices commonly found in edge environments. The improved AES algorithm transitions from a single-threaded encryption and decryption process to a three-threaded design, reducing the ten-round operation to seven rounds to enhance both speed and energy efficiency. The enhanced RSA algorithm replaces the traditional dual-prime system with a triple-prime system, increasing the number of primes while reducing the bit length of each prime. This modification optimizes computational efficiency and strengthens security.Furthermore, we investigate the feasibility of integrating the RSA and AES algorithms and propose a novel RSA-AES hybrid algorithm MRA. This fusion approach leverages the strengths of both algorithms, encrypting the AES key using the improved RSA algorithm to bolster data security while maintaining efficient transmission.Performance evaluations of the RSA-AES hybrid algorithm demonstrate its exceptional capability in securing data transmission within edge scenarios,and the security of this hybrid algorithm is analyzed. The experimental results highlight that this algorithm not only ensures robust data security but also achieves high transmission efficiency, offering a reliable and practical solution for secure communication in edge environments.

With the rapid development of internet technology and the increasing popularity of e-commerce, data encryption technology plays a very important role in data security. Information security has two aspects: security protocol and cryptographic algorithm and the latter is the foundation and core technology of information security. Advanced Encryption Standard (AES) encryption algorithm is one of the most commonly used algorithms in symmetric encryption algorithms. Such algorithms face issues when used in the context of key management and security functions. This paper focuses on the systematic analysis of these issues and summarizes AES algorithm implementation, comprehensive application and algorithm comparison with other existing methods. To analyze the performance of the proposed algorithm and to make full use of the advantages of AES encryption algorithm, one needs to reduce round key and improve the key schedule, as well as organically integrate with RSA algorithm. Java language is used to implement the algorithm due to its large library, then to show the efficiency of the proposed method we compare different parameters, such as encryption/decryption speed, entropies and memory consumption...) with a classic algorithm. Based on the results of the comparison between AES and the hybrid AES algorithm, the proposed algorithm shows good performance and high security. It therefore can be used for key management and security functions, particularly for sharing sensitive files through insecure channel. This analysis provides a reference useful for selecting different encryption algorithms according to different business needs.

Wireless Sensor Networks (WSNs), comprising of tiny nodes with limited energy, computational and communication resources, are being widely used in various application areas ranging from pollution and weather monitoring to military. Even though every application may not require data to be exchanged in a secure manner, few WSN applications may have certain security requirements. The data is encrypted by a sender and sent over the wireless links and the same is decrypted at the receiver. To meet this purpose, symmetric key cryptographic (SKC) algorithms may be used. Such SKC primitives require keys to be made available before carrying out the data transfer between the nodes. Alternately, Public Key Cryptographic techniques, such as RSA algorithm can be considered. Even though, RSA is a popular algorithm providing good security level, it is computationally intensive involving large key sizes. The RSA can not be used in WSNs, as the nodes have limited resources. Presently, it is infeasible to implement the RSA algorithm using any of the WSN nodes commercially available. Elliptic curve cryptography (ECC), another public key cryptographic (PKC) algorithm providing same level of security with smaller key size requirements, can be used as an alternative in order to provide security in WSN applications. ECC encryption and decryption use domain parameters, which includes the Generator point to be published. In most of the outdoor WSN applications, the deployment of the nodes is random and the nodes could be captured and an attacker could launch man-in-middle (MIM) attack, and break the public key thereby leading to security breach in the network. A technique to overcome such an attack is proposed in this work and the same is compared with two other similar approaches.

Ensuring information security in public sector information systems is now more important than ever. Advances in technology and information have not only made daily life easier, but also made the opportunities for cybercrimes vast and inevitable. This study aims to create a framework for evaluation that measure the maturity level of information security in information systems by integrating existing frameworks, NIST Cybersecurity Framework (CSF) and COBIT 2019. The result of this framework development is implemented in a public sector organization called PT XYZ, which has an information system as a tool to assist in the implementation of public services. The Capability Maturity Model Integration (CMMI) method is used to calculate the maturity level. The implemented approach resulted in information security maturity evaluation framework for information systems. This framework includes 118 activities which are divided into 23 categories. The distribution of the integration of the two frameworks contributes 61% activities, the NIST CSF contributes 8% and the COBIT 2019 framework contributes 31% activities. The measurement result of the information security maturity level in the information system at PT XYZ shows that all functions are at level 1 or the initial level. PT XYZ's low information security maturity reveals the critical need for stronger data protection and system resilience. This study introduces a novel approach to demonstrating a practical methodology for integrating two frameworks. The resulting framework enables public sector organizations to assess their security posture, identify areas for improvement, and enhance resilience against cyber threats, strengthening public service and safeguarding data.

In today's technology, ever increasing number of electronics applications require secure communication, for example the Internet of things devices. Elliptic Curve Diffie Hellman (EC-DH) Algorithm has emerged as an attractive and effective public-key cryptosystem. Elliptic curves are widely used in various key exchange techniques that include the Diffie-Hellman Key agreement scheme. When contrasted with conventional cryptosystems like RSA, ECC offers equivalent security with smaller key sizes, which results in lower power consumption, speedier calculations, and also lower memory and transmission capacity (bandwidth) reserve. This is particularly valid and helpful for applications like IoT gadgets, which are regularly constrained regarding their CPU processing speed, power, and area. This work includes the software and hardware implementation of Diffie-Hellman, Elliptic Curve Diffie-Hellman (ECDH) Key agreement algorithm, and RSA algorithm. The proposed work also involves analysis of power, performance, area, and their comparisons thereof. The comparison is based on metrics obtained, after implementing the algorithms in synopsys using 90 nm UMC Faraday library. The ECDH algorithm is found to be better than others as far as power and area are concerned.

To enhance the security of data transmission in Bluetooth communication, a hybrid encryption algorithm based on DES and RSA is proposed. The currently used encryption algorithm employed by the Bluetooth to protect the confidentiality of data during transport between two or more devices is a 128-bit symmetric stream cipher called E0. It may be broken under certain conditions with the time complexity O(2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">64</sup> ). In the proposed hybrid encryption algorithm, instead of the E0 encryption, DES algorithm is used for data transmission because of its higher efficiency in block encryption, and RSA algorithm is used for the encryption of the key of the DES because of its management advantages in key cipher. Under the dual protection with the DES algorithm and the RSA algorithm, the data transmission in the Bluetooth system will be more secure. Meanwhile, it is clear that the procedure of the entire encryption is still simple and efficient as ever. In addition, the confidentiality of the hybrid encryption algorithm is also discussed.

For implementing the data safe transmission in Internet, a safe transmission mechanism which base on RSA and triple DES algorithm is put forward. The mechanism makes full use of advantage of DES and RSA. Because encryption speed of triple DES algorithm is faster than RSA algorithm for long plaintext, and RSA algorithm distribute key safely and easily. Date encryption security of triple DES algorithm is far higher than DES algorithm. Digital abstract algorithm MD5 is adopted in this mechanism. Through comparing the digital signature which is transmitted by dispatcher and digital signature result of plaintext which is got by receiver through MD5 algorithm, data security can be guaranteed. This mechanism realizes the confidentiality, completeness, authentication and non- repudiation. It is an effective method to resolve the problem of safe transmission in Internet.

Data security is needed in terms of communication. To guarantee data security, a technique is needed to make data and information called Critography. This study aims to analyze the process of Super Encryption in symmetric and asymmetric criterias using the Triple DES Algorithm and the RSA Algorithm. This can improve data security so that data is more confidential. The method used in Triple DES which is also called the symmetric algorithm is the OFB (Output feeback) method, and the RSA Algorithm (Riverst - Shamir-Adleman) which is an asymmetric algorithm using a random number system so that when these two algorithms are combined in the Super Encryption process the more accurate the data security. Super DES Triple Encryption and RSA algorithm analysis shows that the data created by text will be encrypted into ciphertext using both methods and re-described, so that the security of the data is relatively safe. Super Encryption on the two methods Algorithm is done because the level of complexity is difficult to make Cryptanalysts to steal data and the Encryption process becomes slow but data security becomes safer and not easy to attack Cryptanalysts. The problem in this research is how to increase encryption security and speed up the encryption process by combining the RSA and Triple DES methods.

With the development of information technology, electronic data exchange to some extent takes the place of the traditional transaction based on paper contract, which challenged the legal system and the information security system while facilitating the transaction. This paper studied the typical procedures of signing e-commerce contract, found that there are some problems on legal and operation levels, especially on the trusted third party system, and this paper proposes improved ecommerce certification security using contract protocol based on RSA and DSA algorithm.

Now a days, as more and more information is communicated via computers, the need is to ensure that this information is secure and information can be secured by the means of encryption algorithms. Securing information refers to the methodologies that are implemented to protect sensitive information from misuse or disclosure as it causes risk. Encryption is the process of conglomerating or scrambling a message so that only the intended recipient can read it. With the fast progression of digital data exchange in electronic way, Information security is becoming much more important in data storage and transmission. With the evolution of human intelligence, the art of cryptography has become more complex in order to make information more secure. Various encryption algorithms are deployed to make information more secure. In this paper, a survey of RSA, DES and AES encryption algorithms are presented.

The primary operation performed by cloud computing is to provide dynamic storage capacity and security to its users.
