摘要:
A data storage unit can store an encrypted medium device key Enc (Kcu, Kmd_i), and a medium device key certificate (Certmedia). A controller can include an information recording unit to store a controller key (Kc) and first controller identification information (IDcu). A key generation unit executes a one-way function calculation based on the controller key and the first controller identification information to generate a controller unique key (Kcu). An identification information generating unit executes a one-way function calculation based on the controller key and the first controller identification information to generate second controller identification information (IDcntr). A key encryption unit encrypts the medium device key (Kmd_i) by the controller unique key (Kcu) to generate encrypted medium device key Enc (Kcu, Kmd_i). A key exchange unit executes an authentication key exchange process with a host device using the medium device key (Kmd_i) and the medium device key certificate (Certmedia).
摘要:
A method of operating a computer system includes: obtaining, at the computer system, verification-input information associated with each of multiple hardware components of the computer system; cryptographically processing, at the computer system, the verification-input information to obtain a cryptographic result; and determining, at the computer system, whether to allow or inhibit, depending upon a comparison of the cryptographic result with a verification value, further operation of at least one of the hardware components.

A semiconductor device in related art has a problem that security on confidential information stored is insufficient. A semiconductor device of the present invention has a unique code which is unique to a device and generates unique code corresponding information from the unique code. The semiconductor device has a memory region in which specific information obtained by encrypting confidential information is stored in a region associated with the unique code corresponding information. The specific information read from the memory region is encrypted with the unique code corresponding information to generate the confidential information.

An asset management system is provided, which includes a hardware module operating as an asset control core. The asset control core generally includes a small hardware core embedded in a target system on chip that establishes a hardware-based point of trust on the silicon die. The asset control core can be used as a root of trust on a consumer device by having features that make it difficult to tamper with. The asset control core is able to generate a unique identifier for one device and participate in the tracking and provisioning of the device through a secure communication channel with an appliance. The appliance generally includes a secure module that caches and distributes provisioning data to one of many agents that connect to the asset control core, e.g. on a manufacturing line or in an after-market programming session.
摘要:
A smartcard (30) having a state machine (380), such as a microcontroller kernel and a non-secure memory (312) capable of storing a Random-ID code, where the non-secure memory is electrically coupled to the state machine. A random number generator (330) may be used for generating a new Random-ID code or a new Random-ID code may be supplied by a card reader system (300) each time the smartcard interacts with the card reader system. A user interface may be electrically coupled to the random number generator (330) so that a user may initiate generation of the new Random-ID code by the random number generator for storage in the non-secure memory (312).
