<p>FIELD: computer engineering. SUBSTANCE: hardware unit is designed as integral circuit and serves for ensuring conformance to license agreement. It has volatile memory which stores unique allocated pair of encrypting keys, digital device certificate which provides authentication, and public encrypting key which is provided by manufacturer and is supplied with cryptographic algorithm. In addition device has processing unit which executes cryptographic algorithms for processing information that is entered into hardware unit and provides transmission of processed information to volatile memory. In addition device has random number generator which generates unique pair of keys. EFFECT: remote transmission of access rights for executing licensed software from one hardware unit to another similar unit. 16 cl, 9 dwg</p> |
