Abstract

This paper describes some software optimizations for AES-GCM over short messages, applicable for modern processors that have dedicated instructions. By processing two (short) messages in parallel, we achieve better performance than by processing twice, back-to-back, a single (short) message. Additional performance is gained if the using application collects several messages, sorts them by order of length, and the feeds them (in pairs) to the two-message AES-GCM function. For example, our experiments carried out on the latest Intel processor (micro architecture codename Skylake), over a realistic distribution of message lengths, our optimization achieves up to 1.95x speedup, compared to OpenSSL.
