Making AES Great Again: The Forthcoming Vectorized AES Instruction

摘要

6.1 Introduction AES is the most ubiquitous symmetric cipher, used in many applications and scenarios. A prominent example is the exponentially growing volume of encrypted online data. Evidence for this growth, which is strongly supported by the industry (e.g., Intel's new AES-NI instructions [1-3], and Google's announcement [4] on favoring sites that use HTTPS) can be observed, for example, in [5] showing that more than 70% of online websites today use encryption.
