摘要： A method and system for providing a client (102) with a copy of the authorization data that can be accessed and used by the client. The method is well-suited to key management protocols that utilize the concept of tickets. Two copies of the authorization data, a client copy and a server copy, are included within and forwarded to the client where the client is requesting a ticket for a specific application server (106). The client is capable of accessing the client copy of the authorization data such that the client can verify requests, and determine authorization of use for content and/or services requested.

摘要： The present invention reduces the exposure of keying material to intermediary devices in a communication channel between first and second servers. In one embodiment, a second server receives a first half of media stream keys from a first server. The second server uses a Kerberos-based Application Request and tickets to communicate the second half of the media stream keys to the first server. Using this approach, the exposure of the media stream keys is reduced to only the servers.

摘要： The present invention is a method and system for accessing digital content stored on a computing device. An agreement between a subscriber and a content provider allows the subscriber to lease the digital content from the content provider, and download the digital content from a content server operated by the content provider. The method retrieves a service ticket for the computing device, and retrieves content rights for the digital content. The service ticket includes authorization data, and a session key, where the authorization data include authorized subscription services for the computing device. The content rights include required subscription services for the digital content and are delivered authenticated with the session key. The method allows access to the digital content when the authorized subscription services included with the authorization data match the required subscription services included with the content rights.

摘要： A method, device and system for authenticating a programmable hardware device, such as a programmable hardware chip, and a command received by the programmable hardware device. A secure processor or other trusted source authenticates the programmable hardware chip by verifying, with the secure processor's own verification key, a random number sent to the programmable hardware chip and encrypted using a verification key embedded within the programmable hardware chip, since the nature of the encryption is such that only the original logic function that includes the verification key can encrypt the data correctly. A command received by the programmable hardware chip is authenticated by verifying that a command authentication token received by the programmable hardware chip is generated using the correct command authentication key and consequently verifying that the command is received from the secure processor, as only the party who has the command authentication key can encrypt the data correctly.

摘要： A system and method for securely distributing PKI data, such as one or more private keys or other confidential digital information, from a PKI data generation facility to a product in a product personalization facility that is not connected to the PKI data generation facility and is assumed to be a non-secure product personalization facility. The system includes a PKI data loader for securely transmitting the encrypted PKI data transferred from the PKI data generator to a PKI server at the product personalization facility. The PKI server then transfers the PKI data to the product of interest, typically via a PKI station acting as a proxy between the PKI server and the product. In each communication step, PKI data being transferred is encrypted multiple times and the system is designed such that if any intermediate node is compromised with all of its keys, the overall system has not yet been compromised.

摘要： A method of encrypting a unique cryptographic entity (UCE), where a client device receives a global-key (GK-) encrypted UKD comprising a GK-encrypted UCE and a GK-encrypted unit key number (UKN). The client device verifies that the GK-encrypted UKN is the same as a pre-provisioned value and then decrypts the GK-encrypted UKD using a global key (GK). The client device then re-encrypts the decrypted UKD using a device user key (DUK) to determine a DUK-encrypted UCE and a DUK-encrypted UKN. The DUK-encrypted UKN is verified as not equal to the GK-encrypted UKN. The DUK-encrypted UKN is then appended to the DUK-encrypted UCE to form a DUK-encrypted UKD and stored in a memory.

摘要： In one embodiment, a method includes receiving a revocation request for revoking a model type of a device. A first computing device determines a list of device unit identifiers (UIDs) that are associated with the model type from a database. The device UIDs are for devices of the model type manufactured by a first entity. The method adds the list of device UIDs to a device revocation list and outputs the device revocation list to revoke a validity of secure information associated with devices associated with the list of device UIDs.

摘要： A method and system for unlocking diagnostic functions in a hardware device for a user. The method obtains a signed permission object for the hardware device, and validates the signed permission object. A memory of the hardware device stores a device identifier and a last recorded sequence number. The signed permission object includes a sequence number and is associated with an expiration counter having an initial value that indicates a lifetime for the signed permission object. When the signed permission object is valid, the method updates the expiration counter to decrease the lifetime of the signed permission object, stores the sequence number associated with the signed permission object as the last recorded sequence number in the hardware device, and unlocks the diagnostic functions for the user based on the signed permission object.
