C-testable S-box implementation for secure advanced encryption standard

We propose a C-testable S-box implementation which is one of the most complex blocks in AES hardware implementation. Only 12 constant vectors are sufficient to achieve 100% fault coverage in the S-box. C-testability is achieved with an extra hardware overhead of 8.2 percent.
