,wherethegoalistoachieveareaandthroughputefficiencybyexploitingthestructural similarities of the ciphers at an algorithmic level. We present two case studies to support our idea. First, we propose the merger of SNOW 3G and ZUC stream ciphers, which constitute a part of the 3GPP LTE-Advanced security suite. We propose HiPAcc-LTE, a high performance integrated design that combines

PAcc-LTE, a high performance integrated de-sign that combines the two ciphers in hardware, based on their struc-tural similarities. The integrated architecture reduces the area overhead significantly compared to two distinct cores, and also provides almost double throughput in terms of keystream generation

proposals, including some eSTREAM candidates. As a result, we elaborate on the design criteria for the development of secure and efficient stream ciphers. The best-known building block is the linear feedback shift register (LFSR), which can be combined with a nonlinear Boolean output function. A powerful

In this paper we present a new class of stream ciphers based on a very simple mechanism. The heart of our method is a Feedback with Carry Shift Registers (FCSR) automaton. This automaton is very similar to the classical LFSR generators, except the fact that it performs operations with carries. Its

Chaotic and classical (binary) stream ciphers are compared with respect to their cryptographical properties. Possible synchronization schemes, algebraic and analytical properties as well as design and implementation aspects are discussed. For two example classes with similar system structures

In this paper, the hardware design of a recently proposed mode of operation for a block cipher, referred to as Statistical Cipher Feedback (SCFB), is investigated. Specifically, we examine a structure which employs serial transfer from the Plaintext Queue to the Ciphertext Queue. SCFB mode

that underlie on-going studies of electronic negotiations are identified. This provides a basis for integration of different theories and approaches for the specific purpose of the design of effective electronic negotiations. Drawing on diverse streams of literature in different fields such as economics

Similarly, technology plays an essential role in framing the relationships of experience: for instance, human reproductive technology frames family relationships and sexuality. Therefore, we must integrate technology, on its own ground, as a speci c layer of the social structure

the extracted clusters in real-time, we present an integrated computation strategy C-SGS, which piggybacks the generation of cluster summarizations within the online clustering process. Lastly, we design a mechanism to efficiently execute cluster matching queries, which identify similar clusters for given

For maximal efficiency, the integrity checks are implemented using instructions that will soon be hardware-accelerated on commodity x86-x64 processors. The approach
