In the hostile environment, use of pseudo-random numbers in encryption algorithm has become difficult due to increased computing power of attackers. To overcome from the hackers true random number generator solving by giving unique random sequence Authors recommend based on experiment to add parameters dependencies of analog Phase-Locked Loop (PLL) based on TRNG, and it also tries to optimize few parameters using Genetic algorithm (GA). The proposed approach selects optimum values for different parameters and increases flexibility, resource utilization, throughput Digital architecture for optimized TRNG is obtained using Altera platform. Implementation the optimized TRNG on ALTERA QUARTUS-H DEO board gives enhancement R and S parameters by 42.18% and 38.67% respectively.

Wireless sensor networks are one of the pioneer technologies of the new century. The low cost of these networks makes them applicable to a variety of areas from battlefields and environment monitoring to health and house appliances. A sensor network is composed of a large number of low cost sensor nodes, which are densely deployed for a specific application inside a usually small environment [1]. Unfortunately their low cost restriction imposes a kind of conservative view on resource consumption. Network setup is one of the power consuming procedures in initialization of the network. In the setup stage, the base station constructs the routing table of all nodes. The total energy of network setup is just before the main function of the network, so decreasing this energy helps the network to perform more functions before its energy exhausts. The purpose of this paper is to decrease the overall energy of setup phase in two ways, first Tiny encryption algorithm (TEA) for security purposes, which are essential for any wireless network against adversaries and unauthorized accesses. This encryption algorithm decreases the amount of computations and memory consumptions. Further more, it defines some kinds of groups to decrease the number of message exchanges and amount of traffic and hence the energy consumed Simulation results show our proposed method decreases the total amount of energy consumptions in the setup stage and convergence time of the route table compared to the traditional setup method.

The paper presents a novel chaotic encryption algorithm which can be used to improve the communication security. An uncomplicated process of chaotic substitution permutation network (SPN) with variable control parameters is proposed to form a robust chaotic cryptosystem. A new chaotic generator, firstly proposed by Lozi, is used for this purpose. For the new cryptosystem, the results of the statistical NIST tests for pseudo-randomness showed to be successful. The system performances are significantly improved after a chaotic under-sampling of the output signal.

Masking is one of the major countermeasures against side-channel attacks to cryptographic modules. Nassar et al. recently proposed a highly efficient masking method, called Rotating S-boxes Masking (RSM), which can be applied to a block cipher based on Substitution-Permutation Network. It arranges multiple masked S-boxes in parallel, which are rotated in each round. This rotation requires remasking process for each round to adjust current masks to those of the S-boxes. In this paper, we propose a method for reducing the complexity of RSM further by omitting the remasking process when the linear diffusion layer of the encryption algorithm has a certain algebraic property. Our method can be applied to AES with a reduced complexity from RSM, while keeping the equivalent security level.

An algorithm of quantum image encryption based on a normal arbitrary superposition state (NASS) is proposed by using quantum geometric transform, phase-shift transform, and quantum Haar wavelet packet transform (QHWPT) in this paper. Firstly, to scramble an image, we design an implementation circuit of quantum image pixel exchanges along diagonal lines. Next, 2((n+1)) - 2 keys randomly distributed between 0 and 2 pi are encoded in the encryption algorithm by using phase-shift transform. The huge key space makes it difficult to attack encrypted images. Then, we store image information in low frequency using QHWPT to improve encryption effect. After that, the encryption algorithms of gray image and color image are simulated by using MATLAB, respectively. Meanwhile, evaluation indexes such as histogram, complexity and correlation of adjacent pixels are analyzed. Simulation experiments show that the proposed algorithm is valid.

We present a method and tool for examining an FPGA-based circuit, in particular an implementation of a cryptographic algorithm, subjected to a fault injection attack based on clock glitching. The proposed approach offers some unique features that allow us to thoroughly analyse the impact of injected faults on the operation of the circuit. In particular, through precise adjustment of the frequency of an external clock generator, the number of faults occurring at the output of the circuit under test can be observed and controlled. The effectiveness of the proposed approach has been assessed for the AES implementation, leading to a number of practical guidelines that may be essential when planning experimental studies on fault injection in FPGA-based circuits.

In general, all kinds of aircrafts have the flight data storage systems such as DTS, Black-box and etc. Data to be stored in such equipment contains very important information that is related to the flight performance and security. For effective storing of the critical information that is included in the flight data, the compression or encryption is essentially required. In present, the flight data is stored without compression unlike voice data, but the compression and secure processing are needed to the efficient storing and the security of flight data in case of the fighter. In this paper, we propose a real-time data storage system that is composed of the compression of the flight and voice data based on DPCM, the encryption of the compressed data using AES encryption algorithm and the re-arrangement of the encrypted data by shuffling technique. The proposed system is implemented in hardware using Verilog HDL and we tested the performance of the system with the simulation flight and voice data. As a result, we found that the proposed system compress the data efficiently and enhances security characteristics.

The recent rise in the popularity of mobile computing has brought the attention of mobile security to the forefront. As users depend more on tablets and smartphones, sensitive data is left to be secured using devices with vastly weaker resources than a typical computer. As mobile technology matures, the industry is starting to provide devices with multiple CPU cores in addition to other coprocessors such as GPUs. By using RenderScript, a new language technology on the Android platform, we hope to utilize the power of parallelism to increase the efficiency of the Blowfish encryption algorithm, while at the same time leveraging the power of RenderScript's heterogenous execution to cope with the quickly changing mobile architectures in order to make the use of data encryption more feasible on a mobile platform. Experimental results demonstrate the effectiveness of RenderScript.

Wired Equivalent Privacyis use to secure wireless networks specifically wireless LAN (Wi-Fi). The core of WEP protocol is the RC4 (Ron's Code-4) algorithm, this paper start with introductory section about description on the WEP protocol and RC4 algorithm. Section 2 briefly examine the security threats, weaknesses of WEP and RC4-Section 3;describe methodology where three important enhancements into the original WEP protocol is describe. First one is the modification to the original RC4 algorithm to make it more secure and even faster. Second one is a novel approach to increase the size of the initial vector without increasing the overall size of the 64 bit session key used in WEP. Third one is providing a provision to dynamically change the secret key before gelling any possibility to crack the secret key from the encrypted data packets. Last section, Results shows that our algorithm provides much better security as well as encryptiontime efficiency and less correlation between encrypted data than the previous works done on WEP or RC4.
