Abstract

See full text

A system for cryptographically authenticated communication, wherein an activation signal is sent from a communications device to a memory device (410). The memory device derives a random challenge from at least one physical property of the activation signal and sends it back to the communications device (420). A signature is computed using the received random challenge (440) and sent, together with a certificate, to the memory device (450).
