An integrated circuit component for enforcing licensing restrictions. Such enforcement is performed through remote transmission of access privileges for executing a licensed program from the integrated circuit component to another similar component. The integrated circuit component comprising a non-volatile memory for storing a uniquely designated key pair, an authentication device certificate and a manufacturer public key along with cryptographic algorithms, a processor for executing the cryptographic algorithms in order to process information inputted into the integrated circuit component and for transmitting the processed information into volatile memory and a random number generator for generating the uniquely designated key pair internally within the integrated circuit component.

A method for transferring a valid license token between a first and second nodes which allows execution of a licensed software program after the valid license token had been initially provided by a software supplier, the method comprising the steps of: establishing a communication link between a first cryptographic device of the first node and a second cryptographic device of the second node; authenticating said first and second cryptographic devices prior to transferring the valid license token there between; transmitting a query message from said first cryptographic device to said second cryptographic device in order to determine whether said second cryptographic device possesses said valid license token; generating a transfer request message from said first cryptographic device to said second cryptographic device if said second cryptographic device possesses said valid license token; transferring said valid license token from said second cryptographic device to said first cryptographic device; generating a token received message from said first cryptographic device to said second cryptographic device after receipt of said valid license token; and terminating said communication link.
