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 کاملAdvanced Differential Cryptanalysis and GOST Cipher
Differential Cryptanalysis (DC) is one of the oldest known attacks on block ciphers and there is no doubt that it has influenced the design of encryption algorithms very deeply, ever since the 1970s. DC is based on tracking of changes in the differences between two messages as they pass through the consecutive rounds of encryption. However DC remains poorly understood. In this paper we survey s...
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 کاملSecurity Evaluation of GOST 28147-89 in View of International Standardisation
GOST 28147-89 is is a well-known 256-bit block cipher which is a plausible alternative for AES-256 and triple DES, which however has a much lower implementation cost, see [31]. GOST is implemented in standard crypto libraries such as OpenSSL and Crypto++ [25, 45], and is increasingly popular and used also outside its country of origin and on the Internet [23, 24, 31]. In 2010 GOST was submitted...
متن کاملthe impact of morphological awareness on the vocabulary development of the iranian efl students
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
