Design Of Wireless Monitoring Terminal Base On Short Message Service

With the improvement of modern communication technology, mobile communication networks are providing people with more and more quick and convenient service, at the same time, its opening bring obvious information security problem. For example, GSM network equipments in our country transmit voice information in plain text, which gives chance to attackers and invaders. So research of the encryption mobile phone over GSM network has become a hot spot. However, the self-security of the encryption mobile phone is also a problem. Because of its small volume and strong mobility, the encryption mobile phone is easily-lost and difficultly-monitored.The main purpose of this thesis is to design a wireless monitoring terminal base on short message service. It can monitor encryption mobile phone remotely through special short messages over GSM network. Considering the security of GSM network, the content of special short messages are encrypted and signed by the wireless monitoring terminal. In the concrete, the main work in this thesis can be summarized as follows:Introduce the design base of the monitoring terminal, include the basic knowledge of GSM network and short message, related cryptology theories.Design the wireless monitoring terminal total scheme.Finish hardware design of the wireless monitoring terminal.Describe software design process of the wireless monitoring terminal in details.
