Digital Tiger Symbol Authorization Method Based on PKI System

Under modern high-tech conditions, the importance of personnel authorization security is increasingly prominent. A set safe method can ensure that human resources are properly distributed to each unit, thus providing reliable guarantee for successful completion tasks. However, current still paper-based or verbal, prone errors inconsistencies, and difficult verify. In this paper, a digital Tiger Mark based on PKI system proposed, using cryptography technology provide support reliability authorization. This realizes fine authorization, be verified. The uses certificates assign people's identities their respective roles, encryption algorithms enforce access control policies prevent unauthorized access. feasibility verified by us in simulated cross-domain task environment.
