A Study on Fine-Grained Security Properties of Cryptographic Protocols for Formal Analysis Method with Reasoning

摘要

Formal analysis is used to find out flaws of cryptographic protocols. A formal analysis method with reasoning for cryptographic protocols has been proposed. In the method, forward reasoning is used to deduce flaws or situations related to flaws from formalized specifications of cryptographic protocols. Analysts of cryptographic protocols pick up deduced results related to flaws from results of forward reasoning according to some criteria. However, there is no study about the criteria for what are flaws that can be applied to various cryptographic protocols. This paper presents fine-grained security properties that cryptographic protocols should satisfy in order to clarify the criteria. The paper shows the enumerated security properties are correct and valid through analyzing some cryptographic protocols.
