TWO BIT ERROR DETECTION AND SINGLE BIT CORRECTION FOR AES
G Saranya Devi · 2013
The Advanced Encryption Standard (AES) is the private-key cryptographic standard for transferring block of data securely. The faults that accidently occur in the hardware implementation of this standard may cause invalid encrypted/decrypted output that results in losing the original message and/or leaking the secret key information. In order to reach a fault detection scheme capable of detecting faults occurring in the hardware implementation of the AES, the structures of the S-box and its inverse have been modified so that single faults lead to either zero or odd number of erroneous output bits. Thus, such errors can be detected and corrected using SECDED. Keyword: AES, S-box, secret key, fault detection, SECDED.
