On ZK-Crypt, Book Stack, and Statistical Tests
نویسندگان
چکیده
The algorithms submitted to the ECRYPT Stream Cipher Project (eSTREAM) were tested using the recently suggested statistical test named “Book Stack”. All the ciphers except ZK-Crypt have passed the tests. The paper briefly describes the essence of the test. Computer implementation of the test in C++ language is supplied.

Understanding the ZK-Crypts ─ Ciphers for (Almost) all Reasons
The ZK-Crypt combination compact hardware stream cipher engines each include a true random number generator, a stream cipher and a data authenticator based on a fast compact engine and proven "noise sources". The ZK-Crypt II 7.0 K gate and ZK-Crypt 8.2 K gate "engines" output a 32 bit word at each clock cycle with 128 and 160-bit keys, maximizing throughput with very low energy per enciphered b...
متن کاملSecurity Analysis of the ZK Crypt III Stream Cipher and Data Authenticator against Algebraic Cryptanalytic, Differential & Correlation Attacks
ZK Crypt III is a three function system (Stream Cipher, Data Authenticator and True Random Noise Generator) based on an extremely highdiffusion hardware number generator, with an orthogonal dual track feedback mechanism that precludes message modification. This device has only 8000 gates and is designed for simultaneous deciphering and data authentication with single or parallel concatenated un...
متن کاملA stack-based chaotic algorithm for encryption of colored images
In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...
متن کاملOn Efficient Zero-Knowledge PCPs
We revisit the question of Zero-Knowledge PCPs, studied by Kilian, Petrank, and Tardos (STOC ’97). A ZK-PCP is defined similarly to a standard PCP, except that the view of any (possibly malicious) verifier can be efficiently simulated up to a small statistical distance. Kilian et al. obtained a ZK-PCP for NEXP in which the proof oracle is in EXP. They also obtained a ZK-PCP for NP in which the ...
متن کاملModeling and experimental study on the sealing gasket of proton exchange membrane fuel cells
In this study cross section geometry and material of gasket in proton exchange membrane (PEM) fuel cells have been investigated to achieve optimized fuel cell in terms of energy efficiency. The role of gaskets in fuel cells is sealing of gas flow channels and preventing from combination of them. In a PEM stack, gasket with approved geometry that suffers more stress has better sealing. For this ...
