Abstract
A method is provided for authenticating one device to another device. In the method, a first device proves to a second device that a first credential comprising multiple first attributes is valid. The second device proves to the first device that a second credential comprising multiple second attributes is valid. The first device reveals a first attribute of the multiple first attributes to the second device. The second device verifies the first attribute and decides whether to continue revealing attributes. If continuing, the second device reveals to the first device a first attribute of the multiple second attributes. The first device verifies the first attribute of the multiple second attributes. The first device decides whether to continue revealing attributes. Attributes can be revealed until one of the first or second devices end the method or until no attributes of the multiple first and second attributes remain to be revealed.
