Abstract
A method and system for authenticating an authorized user of a remote terminal attempting to interconnect with a computer network over a wireless modem is provided. An encrypted wireless communication channel is established between a remote terminal and a network server for facilitating the authentication process. An authorized user presents an authentication card containing credentials including a user identifier and an authentication encryption key to a remote terminal. The remote terminal establishes a wireless communication channel with a network server which provides a firewall between unauthenticated users and a computer network. The network server and the remote terminal then exchange encrypted information thus verifying the authenticity of each party. The remote terminal and the network server each independently generate a data encryption key for use in establishing a secure encrypted wireless communication channel therebetween.
