Abstract

A method and system for anonymous authentication of a first user device, including sending R between first and second user devices, where R is a result of a one-way function performed on a random number r selected by the first user device, the second user device sending R to a service provider which stores R with a data string T and returns a digitally signed R and T to the second user device, the first user device receiving R and T from the second user device, thereby ensuring that the identity of the first user device remains unknown to the service provider, and the first device opening a communication channel with the service provider, sending the service provider R and T via the communication channel along with a request for the service provider to provide a service, and receiving the requested service from the service provider.
