New Security Concurrent Signature Design

英文摘要
The rapid growth of the Internet has accelerated e-commerce application development. Numerous problems involving Internet trade transaction security remain. Therefore, security and transaction fairness establishment in e-commerce applications is a crucial research topic. A fair exchange protocol enables users to securely obtain information from each other. This has become a widely applied research topic in e-commerce. A concurrent signature eliminates the need for a trusted third party (TTP) or substantial mutual communication between two parties, to provide fair exchange protocol with e-commerce ideas. The concurrent signature concept was proposed by Chen et al. in 2004 EUROCRYPT. Some researchers improved the concurrent signature susceptibility to the message substitution attack defect, but there are still identify authentication and information exchange procedure security issues. This paper proposes a concurrent signature scheme based on elliptic curve cryptography (ECC) that uses the same security strength shorter key length, reduces public storage costs and the calculation and management risks. We strengthen the identity authentication mechanisms to prevent the counterfeiting identity attacks and provide a more confidential protocol through a self-certified mechanism.
