| Abstract （English） |
Nowadays, it is pointed out that storing the secret in nonvolatile memory of the device has a chance to leak the secret because of physical attacks and side channel attacks. In order to solve this, Physical Unclonable Functions(PUF) were proposed. Recently, many encryption methods using PUF have been proposed, and one of typical example is authentication. In this paper, we de ne response to challenge of PUF as probability distribution, and we de ne error rate of authentication and success rate of impersonation attack by interpreting authentication using PUF as hypothesis testing problem. In authentication using PUF, we derive lower bound of success rate of impersonation attack when error rate of authentication is 0. And we de ne arbiter PUF which is one of silicon PUFs as probability distribution. In arbiter PUF, we simulate lower bound of success rate of the impersonation attack when error rate of authentication is 0, and discuss security of arbiter PUF. |
