Abstract
Cryptographic circuits are used in areas that require confidentiality and a secure information exchange. Thus, these circuits use cryptographic algorithms proven resistant to conventional attacks by certified organizations of the state.
For performance reasons, Advanced Encryption Standard (AES) is often physically implemented in cryptographic circuits. This implementation proves make these circuits susceptible to other types of attacks that exploit any kind of information from the system to obtain the secret key.
In this paper, the simulation results indicate that error coverage of our proposed countermeasure archive 99.993%. The comparison of our simulation results with those of the previously reported fault detection schemes shown that our proposed scheme have highest frequency overhead.
