Some Attacks on the Bit-Search Generator
The bit-search generator (BSG) was proposed in 2004 and can be seen as a variant of the shrinking and self-shrinking generators. It has the advantage that it works at rate 1/3 usin...

A Side-Channel Analysis Resistant Description of the AES S-Box
So far, efficient algorithmic countermeasures to secure the AES algorithm against (first-order) differential side-channel attacks have been very expensive to implement. In this a...

Security Analysis of a 2/3-Rate Double Length Compression Function in the Black-Box Model
Abstract. In this paper, we propose a 2/3-rate double length compression function and study its security in the black-box model. We prove that to get a collision attack for the com...

Analysis of the Bit-Search Generator and Sequence Compression Techniques
Abstract. Algebraic attacks on stream ciphers apply (at least theoretically) to all LFSR-based stream ciphers that are clocked in a simple and/or easily predictable way. One intere...

An Improved Security Bound for HCTR
HCTR was proposed by Wang, Feng and Wu in 2005. It is a mode of operation which provides a tweakable strong pseudorandom permutation. Though HCTR is quite an efficient mode, the au...
