A solution of secure communication in the current and future mobile network

The security of current mobile network is not provided. Anyone can easily eavesdrop any information in the mobile network if he wants. To secure wireless information between the mobile terminals, this paper provides a solution based on the abilities of the current mobile terminals. This paper also proposes a mechanism that can secure the communication between the current mobile terminals and the Internet web server. Yield to the capability of the current mobile terminals, the public key techniques cannot be used now. But in the future, the memory space and the computation ability of the mobile terminals will no longer be any puzzles, so certificate and Public Key Infrastructure (PKI) can be used to make wireless communication security. This paper also proposes PKI architecture in the future mobile network. Finally this paper makes an assumption of the network's development and its secure issues.
