Analysis of LFSR Based Snow Family against Guess and Determine Attack
Stream Cipher is a cryptographic primitive that is used to make sure privacy on a communication channel. SNOW family is a typical example of word oriented stream ciphers based on Linear Feedback Shift Register (LFSR). In this paper two versions of SNOW family have been analyzed against Guess and Determine (GD) Attack. Original SNOW 2.0 is an improved version of SNOW 1.0 claimed to be more secur...
متن کاملGuess-and-Determine Attacks on SNOW
This note presents a very simple guess and determine attack on Snow requiring 9 key stream words and about 2 computations.
متن کاملGuess and Determine Attack on Bivium
Bivium is a simplified version of Trivium, a hardware profile finalist of the eSTREAM project. Bivium has an internal state size of 177 bits and a key length of 80 bits. In this paper, a guess and determine attack on this cipher is introduced. In the proposed method, the best linear approximations for the updating functions are first defined. Then by using these calculated approximations, a sys...
متن کاملThe New Heuristic Guess and Determine Attack on Snow 2.0 Stream Cipher
SNOW 2.0 is a word oriented stream cipher that has been selected as a standard stream cipher on ISO/IEC 18033-4. One of the general attacks on the stream ciphers is Guess and Determine attack. Heuristic GD attack is GD attack that represents an algorithmic method to analysis the stream cipher with the variables of the same size. The results of HGD attack on TIPSY, SNOW 1.0 and SNOW 2.0 stream c...
متن کاملOn the computational complexity of finding a minimal basis for the guess and determine attack
Guess-and-determine attack is one of the general attacks on stream ciphers. It is a common cryptanalysis tool for evaluating security of stream ciphers. The effectiveness of this attack is based on the number of unknown bits which will be guessed by the attacker to break the cryptosystem. In this work, we present a relation between the minimum numbers of the guessed bits and uniquely restricted...
