Application Of Authentication In System Of Field Clear Cars' GPS Wireless Transmission

In this paper, we researched the security of position system based on the GPS of field clear cars which designed for the request of the army.According to the particular application of field clear cars in military and made a mature GSM technology of mobile communication as references, this paper presents a new identified authentication system which based on the existing GPS in order to improve the security. We illuminate and analyze in detail GSM authentication firstly in this paper, then adopt two kinds of mature secure algorithm MD5, AES while verify time efficiency and security of the whole authentication. Lastly we simulate the process of authentication by C++.We enhance the security of GPS position data transmission system, particularly improve greatly the security of military data in army and avoid disclosing all the information. It has significant to safeguard security of military communication maneuvers.
