New Linear Attacks on Block Cipher GOST
Defined in the standard GOST 28147-89, GOST is a Soviet and Russian government standard symmetric-key block cipher. GOST has the 64-bit block size and a key length of 256 bits. It is a Feistel network of 32 rounds. In 2010, GOST was submitted to ISO 18033 to become a worldwide industrial encryption standard. GOST 28147-89 has also been published as informational RFC 5830 with IETF. In this pape...
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 کاملImproved Integral Attacks on Reduced-Round CLEFIA Block Cipher
In this paper a new 9-round integral distinguisher of CLEFIA is proposed based on byte-pattern, which is proved in detail. Then by using the partial sum technique we improve the previous result on 11round CLEFIA and proposed integral attack on 12-, 13and 14round CLEFIA with the whitening keys. The 12-round CLEFIA-128/192/256 is attacked with data complexity 2 and time complexity 2, 13round CLEF...
متن کاملImproved Linear Cryptanalysis of SMS4 Block Cipher
SMS4 is a block cipher standard used for wireless communications in China. We analyze a reduced versions of SMS4 by the multidimensional linear cryptanalysis method. Our analysis shows that the 23-round of SMS4 can be attacked with 2 data complexity and time complexity less than exhaustive search.
