Topic: White Paper: Implementation and Performance of AES-NI in CyaSSL Embedd


yaSSL and Intel have jointly published a white paper describing how Intel’s AES-NI can be used with the CyaSSL embedded SSL library. This paper provides a brief overview of the Intel AES-NI instructions and demonstrates the performance gains realized when Intel AES-NI is used in place of a more traditional software-only based AES implementation. The CyaSSL embedded SSL library developed by yaSSL, is used as a test bed in the white paper to perform the comparison as it can be built with either traditional AES or AES-NI support at compile time. As a secondary goal to demonstrating Intel AES-NI performance, this paper explains how to determine if a pre-built SSL library (static or shared) offers built-in support for the Intel Advanced Encryption Standard New Instructions.
