README NSA's VHDL Implementations of the Five Advanced Encryption Standard (AES) Candidate Finalists This tar file contains VHDL models for the five AES finalists. Unpacking the this file will create directories for each of the algorithm versions. Inside each version are the VHDL models, testbenches to exercise the models, vectors, and a sample SYNOPSYS simulator script which details the order in which the components are compiled/built. (hardcopy of the files is approx. 8 inches thick).
