Efficient AES-GCM for VPNs using FPGAs

Abstract

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.

Two-Layer Bus-Independent Instruction Set Architecture for Securing Long Protocol Data Units in Automotive Open System Architecture-Based Automotive Electronic Control Units

“…Many papers have optimized implementations of GCM, increasing its throughput and the speed of its internal operations in application-specific integrated circuit (ASIC)-based architectures [19][20][21][22][23] or field programmable gate array (FPGA)-based architectures [24][25][26][27][28][29][30][31]. GCM is also used in network-based systems to secure communication [32][33][34][35][36][37]. GCM has been used in automotive [38] and IOT domains [39,40] as well.…”
