Digital Sensors and Sensor Sysstems


Abstract: Due to the use of wireless transmission and open networks, mobile communications are faced with enormous security threats. This study focuses on security mechanisms of the civil air defense and disaster warning control system based on CDMA wireless access. The working principle and process of authentication and data encryption are presented in detail. Further we propose and develop a novel hybrid cryptosystem combining AES and ECC for this control system in order to achieve the convenience of a public-key cryptosystem and the efficiency of a symmetric-key cryptosystem. Providing high security and encryption efficiency as well as simple management of keys, the proposed cryptographic approach can meet the requirements for security and real-time-ness of data transmission in the wireless access control system.


Keywords: CDMA wireless access, Security mechanism, Data encryption, Hybrid cryptosystem.
