Abstract

This contribution describes general considerations for evaluating the quality of a cryptographic implementation, with a strong focus on hardware implementation of stream ciphers. In particular, the features area e?ciency, power, and secure implementation are discussed. Even though the main target of the treatment here are stream ciphers, some of the thoughts presented are directly applicable to other crypto algorithms such as block ciphers.
