Abstract:

The problem  lacking  privilege management still exits in the identity based encryption system. To solve this problem, a new scheme of the privilege management mechanism of identity based encryption system was put forward, which is named  privilege management of identity based encryption system based on trust service. In the scheme, the idea and algorithm of the threshold are used to manage the services of the domain. Trust inheritance is applied in the researches of privilege management mechanism to assign roles to users. The privilege management mechanism also uses concentration audit to maintain system reliability.
