| Research Abstract |
Scan test has been widely adopted as a default testing technique among most LSI designs, including crypto cores. However, these scan chains might be used as a "side channel" to recover the secret keys from the hardware implementations of cryptographic algorithms. In this research, we propose SD-SFF(State Dependent Scan Flip Flop) which significantly improves the security with ignorable design requirements for crypto hardware implementations.
