Application and Research of a Date Encryption in Monitor System

The paging transmitter is an important equipment in wireless paging system. To ensure reliable work and the safety of the paging transmitter, this paper offers a intelligent monitor system of the special purpose. This paper describes the work principle and the structures of hardware for intelligent monitor system., also analyzes the realization principle used for remote control and measurement from how to design the address codes and the remote control commands. In this paper, the key techniques of intelligent monitor system to ensure the security of data and system reliability such as IDEA (International Data Encryption Algorithm) cryptographic and decipher method, MD5(Message Digest 5) message authentication are illustrated here. Practical test verifies the validity of this intelligent monitor system in improving the security and the reliability of the paging transmitter.
