T/WAPIA 035.3-2020 Information technology security technology entity identification Part 3: Mechanisms using digital signature technology
Basic Information
Scope
Scope: This document specifies an entity authentication mechanism using digital signatures based on asymmetric technology. Digital signatures are used to verify the identity of entities. This document specifies two types of mechanisms: the first type includes five mechanisms that do not introduce an online trusted third party, and the second type includes five mechanisms that introduce an online trusted third party. Among these two types of mechanisms, there are two mechanisms each that implement unidirectional authentication, and three mechanisms each that implement bidirectional authentication. Appendix A specifies the object identifiers assigned to the entity authentication mechanisms regulated by this document. Main technical content: This document defines entity authentication mechanisms using digital signature technology, which are divided into unidirectional authentication and bidirectional authentication. Among them, unidirectional authentication is further divided into single-transfer authentication, double-transfer authentication, and four-transfer authentication according to the number of message transmissions; bidirectional authentication is divided into two-transfer authentication, three-transfer authentication, five-transfer authentication, and seven-transfer authentication according to the number of message transmissions.
