Sensor technology and signal analysis: High security encryption supervision

Security policies have different components; firewall, active directory, and IDS are some examples of these components. Enforcement of network security policies to low level security mechanisms faces some essential difficulties. Consistency, verification, and maintenance are the major ones of these difficulties. One approach to overcome these difficulties is to automate the process of translation of high level security policy into low level security mechanisms. This paper introduces a framework of an automation process that translates a high level security policy into low level security mechanisms. The framework is described in terms of three phases; in the first phase all network assets are categorized according to their roles in the network security and relations between them are identified to constitute the network security model. This proposed model extends the organization based access control (OrBAC) model to include not only access control policy but also some other administrative security policies like auditing policy. Besides, it enables matching of each rule of the high level security policy with the corresponding ones of the low level security policy. Through the second phase, the high level security policy is mapped into the network security model. The second phase could be considered as a translation of the high level security policy into an intermediate model level. Finally, the intermediate model level is translated automatically into low level security mechanism. The paper illustrates the applicability of proposed approach through an application example.

As smart interconnected sensing devices are becoming increasingly ubiquitous, more applications are becoming possible by re-arranging and re-connecting sensing and sensor signal analysis in different pipelines. Naturally, this is best facilitated by extremely thin services that expose minimal functionality and are extremely flexible regarding the ways in which they can be re-arranged. On the other hand, this ability to re-use might be purely theoretical since there are established patterns in the ways processing pipelines are assembled. By adding privacy and technical requirements the re-usability of some functionalities is further restricted, making it even harder to justify the communication and security overheads of maintaining them as independent services. This creates a design space that each application must explore using its own requirements. In this article we focus on detecting activities of daily life (ADL) for medical applications and especially independent living applications, but our setting also offers itself to sharing devices with home automation and home security applications. By studying the methods and pipelines that dominate the audio and visual analysis literature, we observe that there are several multi-component sub-systems that can be encapsulated by a single service without substantial loss of re-usability. We then use this observation to propose a design for our ADL recognition application that satisfies our medical and privacy requirements, makes efficient use of processing and transmission resources, and is also consistent with home automation and home security extensions.

This paper presents the implementation of biometric access control using a fingerprint for the safety and security system of Electric Vehicles (EV). The EVs play a vital role in the minimization of the emission of carbon footprint into the atmosphere. Right now, researchers are giving more attention to the design and development of advanced EVs with more safety and security systems. As the population is gradually increasing, there is a positive correlation between the number of road traffic accidents deaths. These road accidents are unpredictable. The main reasons for road traffic accidents are negligence in driving, drunk and drive also a minor cause is being on the stand and driving. At the same time, the vehicle owner has afraid more because day-by-day vehicle robbery is keep on increasing, which intends to develop anti-theft devices for EVs. In the next few years, with tremendous growth in the electric vehicle market, it is important to design EVs with high security and safety systems. In this paper, an advanced safety and security system is proposed for EVs which ensures the stand removing and vehicle owner through fingerprint recognition. The proposed safety and security systems are implemented and tested in E-Bike the efficacy of the system was found satisfactory.

The instantaneous frequency (IF) and envelope (IE) analysis of signals is very useful in various fields. In this paper, three examples of applications are presented. (1) Representing signals by IF and/or IE. Since signals before and after allpass filtering have the same frequency spectra, there is no way to distinguish them by the spectrum analysis. However, IF and/or IE may show clear differences between them. It is interesting that IF at the onset of a sinusoidal burst signal is twice the frequency of the sinusoid (JAES, September 1980). (2) Analyzing vibratos of violin sounds recorded in CDs in order to find out differences of playing styles of virtuosi such as Grumiaux, Oistrakh, Perlman, and Stern. Some results show clear differences in the speeds and depths of the frequency modulation (vibrato) (ISMA 2004). (3) Analyzing rotation fluctuations of automobile rotating shafts. An electromagnetic or electrostatic sensor located close to a rotating gear measures a quasi-sinusoidal signal. The IF analysis of this signal gives the rotation frequency and details of its fluctuation structure. Not only the steady state rotation, but transient rotation change analysis of a reciprocating engine at the sequence of idling stop and start (ISS) are also possible (https://www.aandd.co.jp/adhome/pdf/catalog/nvhanalysis/casra.pdf).

Coastal sites with typical lagoon features are extremely vulnerable, often suffering from scarce circulation. Especially in the case of shallow basins subjected to strong anthropization and urban discharges, it is fundamental to monitor their hydrodynamics and water quality. The proper detection of events by high performance sensors and appropriate analysis of sensor signals has proved to be a necessary tool for local authorities and stakeholders, leading to early warning and preventive measures against environmental degradation and related hazards. At the same time, assessed datasets are not only essential to deepen the knowledge of the physical processes in the target basin, but are also necessary to calibrate and validate modelling systems providing forecasts. The present paper aims to show how long-term and continuous recordings of meteorological and hydrodynamic data, collected in a semi-enclosed sea, can be managed to rapidly provide fundamental insights on its hydrodynamic structure. The acquired signals have been analyzed in time domain, processed and finally, correlated. The adopted method is simple, feasible and easily replicable. Even if the results are site-dependent, the procedure is generic, and depends on having good quality available data. To show how this might be employed, a case study is examined. In fact, it has been applied to a coastal system, located in Southern Italy, where two monitoring stations are placed in two interconnected basins. The inferred results show that the system is not wind dominated, and that the annual trends in the wind regime, wave spreading and current circulation are not independent, but rather reiterate. These deductions are of great interest as a predictive perspective and for numerical modelling.

CBC mode of 3DES encryption has a wider application and higher security than ECB mode. However, there is a bottleneck of 3DES with CBC mode due to an inherent feedback loop from output to input. In this paper, we propose a method to move XOR gates out of the critical path where two XORs in the junction between two adjacent rounds can be merged into a new XOR gate which then can be absorbed into the precomputation of S-box, thus all the XOR gates are eliminated from the critical path. Our ASIC implementation can achieve a throughput of 2.84Gbps at the cost of 5.84K gates which is superior to others.

As measures to prevent global warming, the needs for energy saving and environmental load reduction are increasing and the technology for efficient use of energy has been introduced into various fields of industry, public welfare and transportation. We propose the energy management system that predicts the demand for energy by the archived operational data, the weather forecast data and so on, and leads the optimal operation plan of equipments and the most effective combination of the energy such as electric power, gas, and heavy oil. This system not only achieves energy saving and environmental load reduction but also supports daily plant maintenance operation and an enhancement of operation management efficiency. This paper describes the function and the application example of our proposed energy navigation system named "Enemap"

UML sequence diagrams are widely used as a behavioral modeling language for interactive systems for their concise and intuitive expression, especially a few high security systems. However, UML sequence diagrams lack precise formal description of semantics when they are used in modeling of the interactions between objects. To solve the problem, this paper proposes a solution by translating the UML sequence diagrams into a formalization system ALCQI-CTL which combines the features of the description logics and computation tree logic, and then formalizing the static semantics and dynamic semantics of UML sequence diagrams. Finally, the example shows that the formalization method is feasible.

Vehicle to vehicle (V2V) communication is a current technological innovation that allows two vehicles to communicate with each other through ad-hoc networks. However, security issues in ad-hoc networks are very high, allowing attacks to take control of vehicles or stealing confidential messages by irresponsible third parties. Therefore, a high security system is needed in ad-hoc networks. The implementation of secret key generation by utilizing Received Signal Strength (RSS) between two vehicles can overcome this problem by generating random key bits. We use HPK (Hybrid Polynomial Regression and Kalman Filter) method to improve RSS correlation and Modified Multi-Bit (MMB) quantization combined with Level Crossing algorithm. Testing is conducted by comparing the performance between HPK method that proposed with another method to increase the reciprocity. The test results show that the HPK method and the combination of proposed quantization can increase the KGR value with a low KDR value. In addition, the secret key bits generated can meet the NIST statistical test.

Organic materials with attractive electronic and optoelectronic properties are in high demand for functional electro-optical device applications. Research on synthetic polymer and organic small molecules has gained a great deal of attention due to their potential applications in low cost, ultra-thin, and flexible products and are expected to have a revolutionary role in modern day life. Basically, organic semiconductors are imperative for a range of optoelectronic applications including organic photovoltaic devices, light-emitting diodes, organic light-emitting transistor and organic field effect transistor-driven photonics since they possess photoluminescence, electroluminescence, and nonlinear optical properties in addition to liquid crystalline, structural patterning, printing and solution casting abilities. Electronic devices based on organic materials can be fabricated by simple processing techniques and are under intense investigation in academic and industrial laboratories because of their potential for mass production of flexible and cost-effective devices models. Organic devices also possess light-weight and transparent advantages compared to silicon-based devices. Significant progress has been achieved in the development of novel materials and new device engineering in the last decade. In this regard, arylene diimide families have shown high promise as useful building blocks for the fabrication of next-generation electronic and optoelectronics devices, providing deeper insight into their transistor characteristics at the molecular scale to practical applications ranging from medicine to high end security systems. These organic compounds are being developed for improved resistance to thermal and environmental stresses, which is one of the major challenges in the field. Several other classes of compounds based on fullerene (C60) and chemically modified thiophenes are also being explored and developed for use in a plethora of devices encompassing interdisciplinary research areas. These devices, owing to their low-cost, ease of synthesis and processing, are expected to pave the way for next-generation electronics with energy-efficient security systems, sensors, photonics, and spintronic memories. In this chapter we present a brief review on the different types of organic devices, their fabrication processes, and recent applications by citing examples of oligomers and polymers.

A high performance lensless optical security system based on the discrete Fresnel transform is presented. Two phase-only masks are generated with what we believe to be a novel and efficient algorithm. Their position coordinates and the wavelength are used as encoding parameters in the encryption process. Compared with previous studies, the main advantage of this proposed encryption system is that it does not need any iterative algorithms to produce the masks, and that makes it very efficient and easy to implement without losing the encryption security.

In this paper, a recovery scheme for safe execution of untrusted programs is presented. In this scheme, when the effects of untrusted program execution is undesirable, system can be easily rolled back to the initial state where the checkpoint is set before the program executed. In high level security systems, only the trustworthy programs, whose names are listed in a whitelist, are allowed to execute. However forbidding all the anonymous programs is unacceptable. In order to reduce the risk of running the uncertified program, many solutions has been proposed to solve the problem, most of which can be categorized into three kinds: detection, protection or recovery. As a recovery scheme, the system doesn't change the program and its context at runtime, and just monitors the process of its execution, records the access it made to system resources, and simultaneously backs up the modification it made to file system. When the record shows the effect of the program is unexpected, the administrator can undo what the program has modified to the file system according to the record. We have implemented a prototype system for Linux operating system using Linux Security Modules (LSM), which can be integrated into other security modules seamlessly. Key advantages of our scheme are that it requires no changes to the untrusted programs or its execution context; it doesn't do anything to hinder the execution process, and only has negligible performance overhead.
