An accountability model for Internet transactions

Abstract

© 2015 IEEE. Internet transaction is increasing significantly due to very fast grown of mobile devices, electronic commerce, and electronic records. Many researchers proposed several protocols to analyze the accountability in Internet transaction. In this paper we propose accountability model and protocol in Internet transaction that have advantages over existing protocols and satisfies essential security properties: Confidentiality, Integrity, Authorization, Authentication, Non-repudiation, Liability and Responsiveness. The protocol is designed using asymmetric cryptography and hash function to ensure that it meets all above accountability properties. The proposed protocol is also analyzed and compared with existing accountability protocols.
