SYSTEM FOR ENABLING AUTHENTICATED COMMUNICATION BETWEEN ENTITIES

摘要

A system for enabling authenticated communication between a first entity and at least one other entity is provided. The system has a second entity and a processor. The first entity and the second entity share transport keys. The second entity has at least one variant key configured to be transported from the second entity to the first entity using the transport keys under control of the processor. The variant key is generated by applying a one way function to a base key and a first bit-pattern in the at least one other entity and is usable to enable the authenticated communication by the first entity with the at least one other entity.
