摘要：Accountability and fairness are very important properties of electronic commerce security protocols. Some protocols are found that cannot achieve their desired security goals. In order to remedy the flaws of the CMP1 protocol, the paper proposes a new fair accountability protocol by adopting cryptographic hash function operation and introducing ftp transmission method. The proposed protocol is verified to satisfy accountability and fairness by utilizing the improved Kailar logic. The performance analysis of the proposed protocol shows that it is better in confidentiality and usability than the CMPI protocol. It can be widely used in electronic commerce applications, such as E-mail and digital contract signing, and so on.
