A secret classified label control model based on the identity-based cryptography

摘要

Aiming at the defects of complex certificate management and high waste of resources in the traditional secure electronic file label management system, a secret classified label (SCL) control model was established based on the identity-based cryptography (IBC). In the secure controlling model of SCL, the digital signature method and the hierarchical access method of electronic documents based on the identity-based cryptography are used to digitally sign the confidential labels and encrypt the confidential documents respectively. Through the modeling of confidential clients, file servers, and key generation centers, the irreproachability of file-level identification and the hierarchical access to files are achieved. Finally, the feasibility, practicability and security of the model are verified by testing the system performance and analyzing the system security.
