Abstract

A method of encrypting data, a telecommunications terminal and an access authorization card are described, which permit utilization of services of one or more service providers independently of a network operator or manufacturer of the telecommunications terminal. Encrypted data is transmitted between a service provider and the telecommunications terminal over a telecommunications network. Data to be transmitted over the telecommunications network is encrypted as a function of the service provider selected.
