An ISP uses these resources to provide Internet services to subscribing customers or users. The ISP controls all aspects of the Internet service provided to the subscriber, including billing, bandwidth management, and e-mail. The ISP also ensures privacy for the subscriber by means of encryption. Leasing network resources from an existing network infrastructure frees the ISP from building an expensive access infrastructure itself while the infrastructure owner is given an opportunity to generate additional revenue from infrastructure. Importantly, neither the user, nor the ISP need to trust the access station (i.e.: the access station is untrusted) through which the access to the IP network is accomplished.
A method for performing mutual authentication and authorization of a user's terminal device (U) and an Internet Service Provider (P) in order to establish secure communication between the terminal (U) and a trusted network element (T) to the Internet via an untrusted access station (A) comprising:
