Search for Impossible Differential of E2
نویسندگان
چکیده
This paper studies the search for the impossible differentials of E2. We apply the Shrinking technique, the miss-in-the-middle technique, and a new search algorithm to E2. As a result, no impossible differential is found for E2 with more than 5 rounds. We conclude that E2 is secure against cryptanalysis using impossible differentials derived by the currently known techniques.

Automatic Search of Truncated Impossible Differentials and Applications
Finding the longest impossible differentials is an essential assignment in proceeding impossible differential cryptanalysis. In this paper, we introduce a novel tool to search the longest truncated impossible differentials for word-oriented block ciphers with bijective S-boxes. It costs polynomial time to return a flag indicating whether a truncated differential is impossible under several filt...
متن کاملA new method for accelerating impossible differential cryptanalysis and its application on LBlock
Impossible differential cryptanalysis, the extension of differential cryptanalysis, is one of the most efficient attacks against block ciphers. This cryptanalysis method has been applied to most of the block ciphers and has shown significant results. Using structures, key schedule considerations, early abort, and pre-computation are some common methods to reduce complexities of this attack. In ...
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...
متن کاملAutomatic Search of Truncated Impossible Differentials for Word-Oriented Block Ciphers (Full Version)
Impossible differential cryptanalysis is a powerful technique to recover the secret key of block ciphers by exploiting the fact that in block ciphers specific input and output differences are not compatible. This paper introduces a novel tool to search truncated impossible differentials for word-oriented block ciphers with bijective Sboxes. Our tool generalizes the earlier U-method and the UID-...
متن کاملRelationships among Differential, Truncated Differential, Impossible Differential Cryptanalyses against Word-Oriented Block Ciphers like RIJNDAEL, E2
We propose a new method for evaluating the security of block ciphers against di erential cryptanalysis and propose new structures for block ciphers. To this end, we de ne the word-wise Markov (Feistel) cipher and random output-di erential (Feistel) cipher and clarify the relations among the di erential, the truncated di erential and the impossible di erential cryptanalyses of the random output-...
