Document Type and Number:
Japanese Patent JP5582663
Kind Code:
B2
Abstract:
The invention relates to a method for generating an identifier for identifying a pair, wherein the pair comprises a cryptographic device and a computer system (1, 2, . . . , i, . . . I), wherein the cryptographic device has a first secret key, wherein a second secret key (118.i) is associated with the computer system, wherein a blocking system (120) for accessing the second secret key of the computer system is provided, wherein the blocking system has a third secret key, and wherein the following steps are carried out for generating the identifier: generating a second public key (116.i) from the second secret key and a third public key (128) associated with the third secret key by means of the blocking system, transmitting the second public key (116.i) to the computer system (i), and generating the identifier from the first secret key and the second public key, using the cryptographic device.
