Abstract:
A method for identification of a physical unit (M) storing a secret identity (SIMEI) and an open identity (IMEI) in memory in a physical unit (M); generating a first parameter (CHv) in the testing device (P); sending an identity request (IR) with the first parameter (CHv) from the testing device (P) to the physical unit (M); generating an electronic signature (SIGt) by use of a first cryptographic function (F3) from the secret identity (SIMEI) and at least the first parameter (CHv) in the physical unit (M), and sending SIGt and the open identity (IMEI) to the testing device (P); and identifying the physical unit (M) by a comparison of the electronic signature (SIGt) sent and a corresponding electronic signature (SIGv) in the generated testing device (P).
