摘要

A method for execution by a device, which comprises: generating a first signature by encrypting an identifier of the device together with first additional data; generating a second signature by encrypting the identifier of the device together with second additional data that is different from the first additional data; releasing the first signature to identify the device on a first occasion; and releasing the second signature to identify the device on a second occasion. Also, a device, which comprises: a memory storing an identifier of the device; a processing entity configured to generate a plurality of different signatures encoding the identifier and to store the signatures in the memory; and a transmit/receive entity configured to identify the device on respective occasions by releasing individual ones of the signatures.
