Hardware Architectures for Cryptanalysis

Popis výsledku v původním jazyce

In this work we explore the resistance of ciphers KeeLoq, Hitag-2, PRESENT and Cryptomeria against variants of brute-force attacks. The ciphers are dedicated for a Lightweight Cryptography, i.e. they find their application area in smartcards or car immobilizers. The ciphers KeeLoq, Hitag-2 and Cryptomeria are used in practice, while the cipher PRESENT has been designed as a replacement for outdated ciphers. We design hardware architectures for cryptanalysis of these ciphers. The architectures are implemented in FPGAs. Where possible, the Cost-Optimized Parallel Code Breaker COPACOBANA is used. The main contribution of this work will insist in (i) design of architectures supporting brute-force attack on individual ciphers and (ii) evaluation of the resistance against brute-force attacks for those ciphers.
