A Near-Practical Attack Against B Mode of HBB
Stream cipher Hiji-Bij-Bij (HBB) was proposed by Sarkar at Indocrypt’03. This cipher uses cellular automata (CA). The algorithm has two modes: a basic mode (B) and a self-synchronizing mode (SS). This article presents the first attack on B mode of HBB using 128 bit secret key. This is a known-pliantext guess-then-determine attack. The main step in the attack guesses 512 bits of unknown out of t...
متن کاملCryptanalysis of Hiji-bij-bij (HBB)
In this paper, we show several known-plaintext attacks on the stream cipher HBB which was proposed recently at INDOCRYPT 2003. The cipher can operate either as a classical stream cipher in the “B mode” or as an asynchronous stream cipher in the “SS mode”. In the case of the SS mode, we present known-plaintext attacks recovering 128-bit key with the complexity 2 and 256-bit key with the complexi...
متن کاملA Stream Cipher Based on Chaotic Permutations
In this paper we introduce a word-based stream cipher consisting of a chaotic part operating as a chaotic permutation and a linear part, both of which designed on a finite field. We will show that this system can operate in both synchronized and self-synchronized modes. More specifically, we show that in the self-synchronized mode the stream cipher has a receiver operating as an unknown input o...

متن کاملA Secure Self-synchronized Stream Cipher
We follow two main objectives in this article. On the one hand, we introduce a security model called LORBACPA for self-synchronized stream ciphers which is stronger than the blockwise LOR-IND-CPA, where we show that standard constructions as delayed CBC or similar existing self-synchronized modes of operation are not secure in this stronger model. Then, on the other hand, following contribution...
