چکیده

We present new attacks on key schedules of block ciphers. These attacks are based on the principles of related-key differential cryptanalysis: attacks that allow both keys and plaintexts to be chosen with specific differences. We show how these attacks can be exploited in actual protocols and cryptanalyze the key schedules of a variety of algorithms, including three-key triple-DES.

We present new attacks on key schedules of block ciphers. These attacks are based on the principles of related-key diierential crypt-analysis: attacks that allow both keys and plaintexts to be chosen with speciic diierences. We show how these attacks can be exploited in actual protocols and cryptanalyze the key schedules of a variety of algorithms, including three-key triple-DES.

Differential Cryptanalysis of GOST

GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 and triple DES, having an amazingly low implementation cost and thus increasingly popular and used [22, 23, 30, 24, 41]. Until 2010 researchers unanimously agreed that: “despite considerable cryptanalytic efforts spent in the ...

First Differential Attack on Full 32-Round GOST

GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 and triple DES, having an amazingly low implementation cost and thus increasingly popular and used [12,15,13,20]. Until 2010 researchers have written that: “despite considerable cryptanalytic efforts spent in the past 20 years...

Cryptanalysis and Design of Block Ciphers

This thesis focuses on cryptanalysis techniques and design of block ciphers. In particular, modern analysis methods such as square, boomerang, impossible differential and linear attacks are described and applied to real block ciphers. The first part of this thesis concentrates on the two most relevant modern cryptanalysis techniques: linear and differential cryptanalysis. These and related tech...

An Improved Differential Attack on Full GOST

GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 and triple DES, having an amazingly low implementation cost and is becoming increasingly popular [?,15]. Until 2010 researchers unanimously agreed that: “despite considerable cryptanalytic efforts spent in the past 20 years, G...
