Abstract

This paper describes some software optimizations for the classical Data Encryption Standard (DES) cipher DES applicable for modern processor architectures that have SIMD instructions. Performance is gained by processing several messages in parallel, compared to processing single messages serially. An added value that the proposed optimizations offer is that the resulting implementations are also side channel protected, unlike other implementations that are found in open source libraries. For comparison, when measured on the latest Intel server processor (Architecture Codename Skylake), our side channel safe implementation is 3.2× faster than that of OpenSSL.
