Block ciphers

From Ecrypt Lightweight

Jump to: navigation, search

This page summarizes the hardware performance for the smallest (in gate-equivalents) reported standard-cell ASIC implementation of each of the block ciphers considered. Note that the diversity of implementation scope, target technologies, and synthesis tools makes direct comparisons between different hardware implementations difficult. The more of these parameters agree, the more reasonable the comparison becomes.

The individual page of each block cipher provides links to the specifications and to a source code, when available.
