Algebraic precomputations in differential and integral cryptanalysis

摘要: Algebraic cryptanalysis is a general tool which permits one to assess the security of wide range cryptographic schemes. techniques have been successfully applied against number multivariate schemes and stream ciphers. Yet, their feasibility block ciphers remains source much speculation. In this context, algebraic mainly deployed in order solve system equations arising from cipher, so far with limited success. work we propose different approach: use Grobner basis compute structural features ciphers, may then be used improve "classical" differential integral attacks. We illustrate our Present Ktantan32.
