  • Patent number: 9214183
    Abstract: A system 100 for securely storing digital data includes a data storage 110 and a physical uncloneable function 120 (PUF), including an input (122) for receiving a challenge and an output (124) for producing a response to the challenge. Means 130 determine an identifier associated with the data storage. Means 140 supply a representation of the identifier to the PUF as a challenge and retrieve a corresponding response from the PUF. A cryptographic unit 150 performs a cryptographic operation for securing or verifying a digital content item stored in the data storage, where the cryptographic operation is performed under control of a cryptographic key derived from the received response.

  • Patent number: 8639949
    Abstract: A secure computing device includes a secure cryptographic module with a key generation unit for generating a cryptographic key in dependence on received input. A storage is used for storing a virtual machine that is executable on a processor and at least one program that is executable on the virtual machine. A virtual machine manager including a unit 132 for determining an identifier associated 5 with the virtual machine, a unit 134 for supplying a representation of the identifier to the secure cryptographic module and retrieving a cryptographic keyfrom the secure cryptographic module; and a unit 136 for, under control of the cryptographic key, decrypting at least a part of data input to the processor and encrypting at least part of data output from the processor when the processor executes the virtual machine.
