Single-Cycle Implementations of Block Ciphers

© Springer International Publishing Switzerland 2016. Security mechanisms to protect our systems and data from malicious adversaries have become essential. Strong encryption algorithms are an important building block of these solutions. However, each application has its own requirements and it is not always possible to find a cipher that meets them all. This work compares unrolled combinational hardware implementations of six lightweight block ciphers, along with an AES implementation as a baseline. Up until now, the majority of such ciphers were designed for area-constrained environments where speed is often not crucial, but recently the need for single-cycle, low latency block ciphers with limited area requirements has arisen to build security architectures for embedded systems. Our comparison shows that some designers are already on this track, but a lot of work still remains to be done.
