Although many strong cryptanalytic tools exploit weaknesses in the data-randomizinig part of a block cipher, relatively few general tools for cryptanalyzing on the other part, the ...
— In the present paper, we introduce high-performance hardware architectures for the 128-bit block cipher CLEFIA and evaluate their ASIC performances in comparison with the ISO/I...
Block ciphers are usually based on one top-level scheme into which we plug “round functions”. To analyze security, it is important to study the intrinsic security provided by t...
When the network is homogeneous, choosing the cipher type for a packet telephony application is simple. It is clear that stream ciphers perform better than block ciphers over land...
