Abstract

Authenticated Encryption (AE) schemes are key-based cryptographic algorithms that provide both goals of confidentiality of message and authenticity of the sender, simultaneously. Traditionally, Advanced Encryption Standard (AES) in Galois Counter Mode (AES-GCM), among several other approaches, has been employed for Authenticated Encryption. However, several lightweight cryptographic applications such as those used in sensor networks or RFID security can benefit from new AE schemes which can be constructed more efficiently. In this paper we provide evaluations for Deoxys, a third round candidate from the ongoing Competition for Authenticated Encryption: Security, Applicability, and Robustness (CAESAR). We describe simplified flow diagrams and a detailed summary on the timing performance, area, memory and energy requirements of AES-GCM and Deoxys, using our own implementations on Altera Cyclone V FPGAs. Our analysis shows that Deoxys requires 10% less energy per bit and 25% less LUTs as compared to AES-GCM.
