| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a formal method for verifying whether Hardware Trojan (HT) exists or not (i.e., HT-freeness) in cryptographic hardware. The proposed method focuses on GF arithmetic circuits which are commonly used for a major part of modern cryptographic hardware. Since the functionality of GF arithmetic circuits can be given by a set of GF equations, the proposed method detects the existence of HTs or verifies HT-freeness by checking the equivalence between GF equations (i.e., circuit specification) and flattened gate-level netlist of a target circuit. In the proposed method, we first derive GF equations (i.e., circuit specification) over a representation of Boolean polynomial ring using the zero-suppressed binary decision diagram (ZDD). We then construct the ZDD representation of the target netlist, and finally check whether or not the two ZDDs are isomorphic, which make it possible to perform an efficient and complete HT-freeness verification. In this paper, we demonstrate the highest efficiency of the proposed method through the experimental verification of GF multipliers with various input length including practical ones used in elliptic curve cryptography, and 128-bit AES hardware datapath. | |
