作者： Dariusz Burak West Pomeranian University of Technology Szczecin West Pomerania Poland

In this paper the results of parallelizing a block cipher based on a spatiotemporal chaotic system and a chaotic neural network are presented. A data dependence analysis of loops was applied in order to parallelize the algorithm. The parallelism of the algorithm is demonstrated in accordance with the OpenMP standard. The efficiency measurements of a parallel algorithm working in standard modes of operation are shown.

This article proposes a reversible information hiding algorithm based on chaos and histogram translation in ciphertext images to address the shortcomings of traditional algorithms such as separation of encryption and information hiding processes, small embedding capacity, and inflexible operation. This article first uses grayscale images as a carrier for digital images, analyzes and studies existing reversible information hiding algorithms in the ciphertext domain of grayscale images, and improves them to solve the problems of existing reversible in-formation hiding algorithms in the ciphertext domain. Secondly, the sender first encrypts the image and then embeds the information;The receiving end can either decrypt and extract information first, or extract and decrypt information first. Finally, we selected a Lena grayscale image with 513 pixels x 513 pixels for the experiment, dividing the image into 4 blocks (r = 4), and scrambling the pixel positions using DLKL transform for each block, with parameters k = 4, n = 7, q = 59. The simulation results show that the algorithm is easy to implement and can effectively improve the capacity of information embedding.

GPU Random Numbers via the Tiny encryption algorithm 10

GPU Random Numbers via the Tiny Encryption Algorithm

Conference on High-performance Graphics

Random numbers are extensively used on the GPU. As more computation is ported to the GPU, it can no longer be treated as rendering hardware alone. Random number generators (RNG) are expected to cater general purpose and graphics applications alike. Such diversity adds to expected requirements of a RNG. A good GPU RNG should be able to provide repeatability, random access, multiple independent streams, speed, and random numbers free from detectable statistical bias. A specific application may require some if not all of the above characteristics at one time. In particular, we hypothesize that not all algorithms need the highest-quality random numbers, so a good GPU RNG should provide a speed quality tradeoff that can be tuned for fast low quality or slower high quality random numbers. We propose that the Tiny encryption algorithm satisfies all of the requirements of a good GPU Pseudo Random Number Generator. We compare our technique against previous approaches, and present an evaluation using standard randomness test suites as well as Perlin noise and a Monte-Carlo shadow algorithm. We show that the quality of random number generation directly affects the quality of the noise produced, however, good quality noise can still be produced with a lower quality random number generator.

In this paper, a cryptographic algorithm design called Tiny encryption algorithm (TEA) is proposed in order to minimize the memory footprint and maximize the speed. The design was targeted for embedded and mobile systems which concern more on speed and space. In TEA, the plaintext is encrypted and decrypted using the operations from mixed (orthogonal) algebraic groups and a huge number of rounds to achieve security with simplicity. At sixty-four (64) Feistel rounds, a total of 2,883 gates are used in the TEA encryption process with 16.72ns delay time while 2,805 gates are consumed in the decryption process with 14.78ns delay time. With these outcomes, the design is possible to be implemented on mobile devices which require considerable extent of security.

Chaotic theory has been applied to image encryption as an effective and robust technique due to its unique properties. In this paper, we introduce a new combined chaotic system, which shows better chaotic behaviors than the traditional ones. Applying this chaotic system to image processing, a new image encryption algorithm is introduced based on the confusion and diffusion in encryption procedure. Experimental results show that the proposed algorithm has a higher security level and excellent performance in image encryption.

Smart Card is something that is used for data transactions quickly and practically. The definition of ”smart” is when a card has a chip implanted. The card is very helpful in the authentication and administration process even during emergencies, such as a patient healthcare record at the hospital. In this case study, patient data should only be accessed and known by people who have rights. So it is necessary for the security of data storage such as cryptography algorithms. The algorithm needed for patient cards is an algorithm that has fast processing capability and a high level of security. So the aim of this study is to implement the Tiny encryption algorithm on Smart Cards. Based on the results of testing in this study the time of encrypting patient data with a total of 600 lines of patient history measuring 30.6 Kb produces an average encryption time of 20.17 ms. While the decryption for the same data takes 17.21 ms which shows very little processing time and the tolerance for waiting time for accessing data. Furthermore, the Avalanche Effect test carried out in the TEA encryption process results 77%, where these results indicate that encrypted data has very random cipher-text results so that the data contents are kept confidential with a high level of security. The results of testing the processing time and AE can be concluded that TEA is an algorithm that has a fast data security process with high security and time that can be tolerated by users.
