Abstract:

Interactive electronic signing is a kind of electronic signature application closely integrated with specific types of key carriers. In the case of attackers remotely controlling the key carriers by the way of hijacking the hosts, interactive electronic signing can effectively prevent attackers from using the legitimate users’ identities to trade or tamper with the information. This article explores the theoretical framework of interactive electronic signing about scheme design based on formal analysis, sums up the design essentials of interactive electronic signing through the investigation, points out that cheat on signing is one of the major security threats of interactive electronic signing, and provides the formal description of the problem. This article also provides the technology route selection of interactive electronic signing under the framework of cryptographic industry standards, and intercompares some interactive electronic signing schemes based on national cryptographic algorithms from the aspect of security risks.

Key words: interactive electronic signing, formal analysis, industrial standards
