Abstract
Official abstract text for this publication.
The invention relates to a method for generating an identifier for identifying a pair, wherein the pair comprises a cryptographic device ( 100 ) and a computer system ( 1, 2 , . . . , i, . . . I), wherein the cryptographic device has a first secret key ( 102 ), 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 ( 126 ), 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for blocking a cryptographic device, the method comprising: storing, by the cryptographic device, a first secret key associated with a first public key, wherein the first secret key is also associated with the cryptographic device and held by the cryptographic device; storing, by a blocking system, a second secret key, wherein the second secret key is associated with the computer system and held by the blocking system; storing, by a blocki…
