Lightweight access authentication method for integrated electronic system

Abstract

The invention discloses a lightweight access authentication method for an integrated electronic system, comprising the steps of subsystem determination, a first authentication and a second authentication, wherein the subsystem determination comprises: determining whether it is the first time for the subsystem to access the integrated electronic system, if so, performing the first authentication after preprocessing, or otherwise, directly performing the first authentication; the first authentication comprises: sending the identity credential to a central control unit by the subsystem, performing the second authentication if the subsystem passes the first authentication of the central control unit, or otherwise, ending the authentication; and the second authentication comprises: after the subsystem passes the first authentication, generating random numbers and challenge credential by the central control unit to perform the second authentication on the subsystem. By considering the circumstance of limited resources of the integrated electronic system, the invention uses a lightweight operation to realize access authentication of the integrated electronic system, thereby ensuring the system security, and effectively defending against replay attack, desynchronization attack as well as forgery attack.

Description

technical field [0001] The invention belongs to the technical field of access authentication, and in particular relates to an integrated electronic system identity authentication with limited resources and an access authentication method capable of resisting replay attacks and desynchronization attacks.

Problems solved by technology

Due to the particularity of the operating environment of the space-borne integrated electronic system, its computing resources, storage resources and other on-board resources are very limited. The traditional access authentication technology with high computing load cannot be applied to the space-borne integrated electronic system. Comprehensive electronic system access authentication has not been studied
