Scope

Scope: This document specifies the system architecture, system functions, system design, and technical requirements for communication protocols of the intelligent connected vehicle key management system, and also proposes security requirements for the operation and management of the key management system. This document applies to the design, construction, operation, and management of key management systems based on cryptographic technology in the field of intelligent connected vehicles, and standardizes the application of key management systems in the field of intelligent connected vehicles. Main technical content: All content related to cryptographic algorithms in this document shall comply with relevant national regulations. All content related to using cryptographic technology to meet the requirements of confidentiality, integrity, authenticity, and non-repudiation shall comply with relevant national and industry standards. This document partially references the People's Republic of China National Standard GB/T 25056-2018 "Information Security Technology - Certificate Authentication System Cryptography and Related Security Technology Specifications". Compared with GB/T 25056-2018, in addition to structural adjustments and editorial changes, the main changes are as follows: a) an introduction section is added; b) concepts and terminology related to intelligent connected vehicles and related acronyms are added; c) the original Chapter 5 "Certificate Authentication System", Chapter 8 "Certificate Authentication Center", Chapter 10 "Requirements for the Operation and Management of the Certificate Authentication Center", and Chapter 12 "Certificate Operation Process" are deleted; d) the original Chapter 6 "Key Management System" is changed to the present Chapter 5 "Overview of the Key Management System" and optimized. "Key backup" is no longer mandatory as a system function requirement, and the "Key destruction" function requirement is added; e) based on the busines
