Related-key cryptanalysis of 3-WAY, Biham-DES, CAST, DES-X, NewDES, RC2, and TEA

چکیده
We present new related-key attacks on the block ciphers 3WAY, Biham-DES, CAST, DES-X, NewDES, RC2, and TEA. Differential related-key attacks allow both keys and plaintexts to be chosen with specific differences [KSW96]. Our attacks build on the original work, showing how to adapt the general attack to deal with the difficulties of the individual algorithms. We also give specific design principles to protect against these attacks.

متن کاملThe Best Differential Characteristics and Subtleties of the Biham-Shamir Attacks on DES
In about every book about cryptography, we learn that the plaintext complexity of differential cryptanalysis on DES is 2, as reported by Biham and Shamir in [2]. Yet few people realise that in a typical setting this estimation is not exact and too optimistic. In this note we show that the two “best” differentials for DES used by Biham and Shamir [1, 2], are not the best differentials that exist...
متن کاملPerformance and Efficiency Analysis of Different Block Cipher Algorithms of Symmetric Key Cryptography
In the era of information technology, security is essential to transmit confidential information (like credit card details, banking transactions etc) over the unsecured network like internet. It is possibility that the information that is being transferred through network of computers or internet being read by other people. For this we need an efficient and secure way to protect our data. Crypt...
متن کاملConstructing Symmetric Ciphers Using the CAST Design Procedure
This paper describes the CAST design procedure for constructing a family of DES-like Substitution-Permutation Network (SPN) cryptosystems which appear to have good resistance to differential cryptanalysis, linear cryptanalysis, and related-key cryptanalysis, along with a number of other desirable cryptographic properties. Details of the design choices in the procedure are given, including those...
