A New Version of the RC6 Algorithm, Stronger against χ2 Cryptanalysis
نویسندگان
چکیده
We analyze the χ cryptanalysis, one of the most successful cryptanalysis technique against the RC6 algorithm. We apply this type of cryptanalysis as distinction cryptanalysis as well as key-recovery cryptanalysis. We present a modified version of RC6 by introducing a very simple data-dependent swapping function in its structure. The conclusions inferred by statistical experiments is that this modified version is stronger against the χ cryptanalysis technique.

MIYAJI and NONAKA : CRYPTANALYSIS OF REDUCED - ROUND RC 6 WITHOUT WHITENING
We investigate the cryptanalysis of reducedround RC6 without whitening. Up to now, key recovery algorithms against the reduced-round RC6 itself, the reduced-round RC6 without whitening, and even the simplified variants have been infeasible on a modern computer. In this paper, we propose an efficient and feasible key recovery algorithm against reducedround RC6 without whitening. Our algorithm is...
متن کاملTime and Space Complexity Reduction of a Cryptanalysis Algorithm
Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...
متن کاملConcurrent error detection of fault-based side-channel cryptanalysis of 128-bit RC6 block cipher
Fault-based side channel cryptanalysis is very effective against symmetric and asymmetric encryption algorithms. Although straightforward hardware and time redundancy based concurrent error detection (CED) architectures can be used to thwart such attacks, they entail significant overhead (either area or performance). In this paper we investigate two systematic approaches to low-cost, low-latenc...

متن کاملImpossible Differential Cryptanalysis of Reduced-Round Midori64 Block Cipher (Extended Version)
Impossible differential attack is a well-known mean to examine robustness of block ciphers. Using impossible differ- ential cryptanalysis, we analyze security of a family of lightweight block ciphers, named Midori, that are designed considering low energy consumption. Midori state size can be either 64 bits for Midori64 or 128 bits for Midori128; however, both vers...
