Various cryptographic protocols are proposed for providing secure services on computer network. Some cryptographic protocols are insecure even under the assumption that used cryptographic algorithms are secure. In evaluating and redesigning an insecure cryptographic protocol, it is useful to analyze attacks against the protocol. We assume that the cost of each operation which can be excuted by the adversary is given. The cost of an attack is defined as the sum of costs of the operations included in the attack. We extend a formal method which verifies the security of a cryptographic protocol to find the lowest cost attack
when the protocol is insecure. |
