Advanced Fault Detection Scheme for AES Architecture

Cryptography is a method that has been developed to ensure the secrecy of messages and transfer data securely. The Advanced Encryption Standard (AES) is the newly accepted symmetric cryptography standard for transferring block of data securely. However, the natural and malicious injected faults reduce its reliability and may cause confidential information leakage. The objective of this paper is to find optimized fault detection schemes for reaching reasonable fault coverage in the high performance AES implementations. In order to provide low cost complexity signature, two sets of error indication flag is used. This structure can be applied to both look-up tables and logic gate for the implementation of S-box and inverse S-box and their parity predictions.
