Description
Summary:Since its acceptance as the adopted authenticated encryption algorithm, AES-GCM has been utilized in various security-constrained applications. This paper describes the benefits of adding key-synthesized property to AES-GCM using FPGAs. Presented architectures can be used for applications which require encryption and authentication with slow changing keys like Virtual Private Networks (VPNs). Our architectures were evaluated using Virtex4 and Virtex5 FPGAs. It is shown that the performance of the presented AES-GCM architecture outperforms the previously reported ones.
