WebAbstract. In this paper, we present techniques to protect bitslice block ciphers against power analysis attacks. We analyze and extend a tech-nique proposed in [14]. We apply the technique to BaseKing, a variant of 3-Way[10] that was published in [8]. We introduce an alternative method to protect against power analysis speci c for BaseKing. WebMost importantly, bitsliced code is immune to cache-related side channels (including timing). As a bonus, it is extremely linear, that makes efficient scheduling of data accesses easier, and there's no branching delay. On the downside of bitslicing: Most importantly, making w simultaneous operations do not match all workloads!
RECTANGLE: a bit-slice lightweight block cipher suitable for multiple ...
WebNov 19, 2015 · In this paper, we propose a new lightweight block cipher named RECTANGLE. The main idea of the design of RECTANGLE is to allow lightweight and fast implementations using bit-slice techniques. RECTANGLE uses an SP-network. The substitution layer consists of 16 4×4 S-boxes in parallel. The permutation layer is … WebJan 29, 2002 · A second-order DPA attack that is optimal under certain assumptions is also proposed.
