A statistical approach to cryptanalysis of a memoryless function of clock-controlled shift registers is introduced. In the case of zero-order correlation immunity, an algorithm for a shift register initial state reconstruction based on the sequence comparison concept is proposed. A constrained Levenshtein distance relevant for the cryptanalysis is defined… (More)

The recently proposed multiplicative masking countermeasure against power analysis attacks on AES is interesting as it does not require the costly recomputation and RAM storage of S-boxes for every run of AES. This is important for applications where the available space is very limited such as the smart card applications. Unfortunately, it is here shown… (More)

It is shown that the amount of true randomness produced by the recently introduced Galois and Fibonacci ring oscillators can be evaluated experimentally by restarting the oscillators from the same initial conditions and by examining the time evolution of the standard deviation of the oscillating signals. The restart approach is also applied to classical… (More)

A general linear iterative cryptanalysis method for solving binary systems of approximate linear equations which is also applicable to keystream generators producing short keystream sequences is proposed. A linear cryptanalysis method for reconstructing the secret key in a general type of initialization schemes is also developed. A large class of linear… (More)

The LILI-128 keystream generator is a LFSR based synchronous stream cipher with a 128 bit key. The design offers large period and linear complexity, and is resistant to currently known styles of attack. LILI-128 is simple to implement in hardware or software.

A new method for digital true random number generation based on asynchronous logic circuits with feedback is introduced. In particular, a concrete technique using the so-called Galois and Fibonacci ring oscillators is developed and analyzed both theoretically and experimentally. The generated random binary sequences may have a very high speed and a higher… (More)
