The complex data integration and interaction of the device and business systems of the security system within airport is the key guarantee of the future intelligent airport operation. The traditional security device management is decentralized and the real-time data monitoring performance is poor. Therefore, the airport has potential safety risks and is difficult to meet the development requirements. In this paper, the intelligent lock system is used to replace the traditional mechanical lock. Then, the airport security management processes based on security identification, intelligent authorization, integrated management and status monitoring have been designed. Using Elliptic Curve Cryptography for unlock code generation and advanced software development architecture, the airport security information management platform and mobile device APP based on intelligent locks has been developed, which achieved airport equipment management, authorization, patrol and unlock services. By this way, it can improve the security and efficiency of airport device security information management.
