摘要:
Methods and systems are disclosed for verifying the use of a client device by a host device in a secure system. In one aspect, a method for authenticating a client device includes receiving, by the client device, a message from a host device, accessing, by the client device, a private key and a unique code stored on the client device, where the unique code is different than the private key, generating, by the client device, a digital signature for the message using the private key and the unique code, and providing, by the client device, the digital signature to the host device for verification of the use of the client device by the host device.
摘要:
An integrated circuit device comprises a processor and a secure protection zone with security properties that can be verified by a remote device communicating with the integrated circuit device. The secure protection zone includes a persistent storage that is configured for storing cryptographic keys and data. The secure protection zone also includes instructions that are configured for causing the processor to perform cryptographic operations using the cryptographic keys. In addition, the secure protection zone includes an ephemeral memory that is configured for storing information associated with the cryptographic operations. The instructions are configured for causing the processor to perform the cryptographic operations on the data stored in the persistent storage and the information in the ephemeral memory as part of a secure communication exchange with the remote device.
摘要:
Systems and techniques for performing cryptographic operations based on public key validity registers are described. A described system includes a controller and a memory structure to store one or more public keys. The memory structure includes one or more validity registers that respectively correspond to the one or more public keys. The controller has exclusive write access to the validity register. The controller can be configured to perform an authentication of a public key, write an authentication status value to the corresponding validity register based on a result of the authentication, and perform one or more cryptographic operations using the public key that are conditional on the validity register indicating an authenticated status for the public key.

摘要:
Apparatus, systems, and methods send an interrogation command from an interrogation and timing apparatus to a timed identification (TID) apparatus. The TID apparatus receives the interrogation command, performs a series of logical operations to calculate a response, and returns the response within a maximum length of time established by the interrogation and timing apparatus. The interrogation and timing apparatus confirms that the length of time between sending the interrogation command and receiving the response is within the maximum length of time and that the response is correct. If so, the TID apparatus is authenticated. Additional embodiments are disclosed and claimed.

A tag for use in identifying and communicating with an electronic device such as a computer is disclosed. The tag is self powered from an RF interrogation signal when the electronic device is not operating. The tag is provided with DC power from the electronic device when it is communicating with the electronic device to which it is attached as a portion of memory of the electronic device.

摘要:
A method of asset control and workstation computer deployment that utilizes a dual port electronic memory identification RFID tag to hold serial number and hardware and software configuration profiles as well as user information. The RFID tag is mapped into the workstation computer memory space and can also be read and written by wireless radio frequency signalling. Serial numbers and MAC address is stored on the tag by the manufacturer. User information, workstation profile and software image information is stored onto the tag while the computer is being received for forwarding to the final workstation destination without the need to unpack and power up the computer. The information stored on the tag is used to allow automated system configuration and software downloading to the computer.
