Distinguishing Attacks on the Stream Cipher Py
The stream cipher Py, which was designed by Biham and Seberry, is a submission for ECRYPT stream cipher competition. The cipher which is based on two large arrays (one is 256 bytes and the other is 1040 bytes) is specifically designed for high speed software applications (Py is more than 2.5 times faster than the RC4 on Pentium III). The paper, for the first time, detects a weakness in the mech...
متن کاملAn Improved Attack on WG Stream Cipher
WG is a synchronous stream cipher submitted to the hardware profile of eSTREAM project. The main feature of this stream cipher is the use of WG transformation. WG uses keys and initial vectors (IVs) of the same lengths 80, 96, 112 and 128 bits. Moreover, IVs of the length 32 and 64 bits are admitted. The most important key recovery attack on WG was presented by Wu and Preneel and uses the weakn...
متن کاملResynchronization Attacks on WG and LEX
WG and LEX are two stream ciphers submitted to eStream – the ECRYPT stream cipher project. In this paper, we point out security flaws in the resynchronization of these two ciphers. The resynchronization of WG is vulnerable to a differential attack. For WG with 80-bit key and 80-bit IV, 48 bits of the secret key can be recovered with about 2 chosen IVs . For each chosen IV, only the first four k...
متن کاملNew Fixed Point Attacks on GOST2 Block Cipher
GOST block cipher designed in the 1970s and published in 1989 as the Soviet and Russian standard GOST 28147-89. In order to enhance the security of GOST block cipher after proposing various attacks on it, designers published a modified version of GOST, namely GOST2, in 2015 which has a new key schedule and explicit choice for S-boxes. In this paper, by using three exactly identical portions of ...
متن کاملDistinguishing Attacks on RC4 and A New Improvement of the Cipher
RC4, designed by Rivest in 1987, is the most widely deployed stream cipher in practical applications. In this paper, two new class of statistical biases inherent in RC4 are depicted and it is shown that the RC4 keystream is distinguishable from random no matter how many initial bytes have been dumped. RC4A, proposed by Paul and Preneel at FSE 2004 to strengthen the security of RC4, is also foun...
