Abstract
This invention relates to an authentication process with an access control and/or payment system that maintains anonymity of the customer towards a third party, characterized in that a single-directional authentication protocol is used to send an authentication sequence that is completely different for each transaction, so that it is impossible for a third party to determine the identity of this customer, or even to determine which transactions are sent by a particular customer.
