Identity authentication and key agreement method suitable for electricity consumption information collection system

Abstract

The invention provides an identity authentication and key agreement method suitable for an electricity consumption information collection system. On the basis of a traditional identity authentication and key agreement method, a digital certificate identity identification mechanism, a signature authentication mechanism using an authoritative institution to inquire the validity of a digital certificate, and a challenge response mechanism based on a symmetric key are introduced to achieve the identity authentication and key agreement of a master station and terminals. The method can effectively resist attacks such as faking of the master station, communication service flow analysis, password analysis and the like, and enhances the safety of the electricity consumption information collection system.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to an identity authentication and key negotiation method suitable for an electricity consumption information collection system. Background technique [0002] The electricity consumption information collection system is a system that collects, processes and monitors electricity consumption information of power users in real time. The electricity, electricity charges, rates and other information involved in the system are related to the national economy and the people's livelihood, and the illegal use and leakage of information will cause national Security, social economy, and power grid operation pose great threats. Therefore, the electricity consumption information collection system should adopt relatively secure identity authentication and key agreement methods to ensure the confidentiality and integrity of transmitted data. At present, SSL communication pr...
