Patent application number | Description | Published |
20090292926 | System and method for controlling features on a device - Trust between entities participating in an upgrade or enablement/disablement process is established and, to facilitate this remotely and securely, a highly tamper resistant point of trust in the system that is being produced is used. This point of trust enables a more efficient distribution system to be used. Through either a provisioning process or at later stages, i.e. subsequent to installation, manufacture, assembly, sale, etc.; the point of trust embodied as a feature controller on the device or system being modified is given a feature set (or updated feature set) that, when validated, is used to enable or disable entire features or to activate portions of the feature. | 11-26-2009 |
20090323944 | METHOD OF PUBLIC KEY GENERATION - A potential bias in the generation of a private key is avoided by selecting the key and comparing it against the system parameters. If a predetermined condition is attained it is accepted. If not it is rejected and a new key is generated. | 12-31-2009 |
20100205433 | SYSTEM AND METHOD FOR REMOTE DEVICE REGISTRATION - A system and method for remote device registration, to monitor and meter the injection of keying or other confidential information onto a device, is provided. A producer who utilizes one or more separate manufacturers, operates a remote module that communicates over forward and backward channels with a local module at the manufacturer. Encrypted data transmissions are sent by producer to the manufacturer and are decrypted to obtain sensitive data used in the devices. As data transmissions are decrypted, credits from a credit pool are depleted and can be replenished by the producer through credit instructions. As distribution images are decrypted, usage records are created and eventually concatenated, and sent as usage reports back to the producer, to enable the producer to monitor and meter production at the manufacturer. | 08-12-2010 |
20100312791 | PARTIAL REVOCATION LIST - A partial revocation list and a system and method for using the partial revocation list for tracking the authenticity of replacement cartridges in a manufactured device to inhibit cloning of the cartridges is provided. A revocation pool is maintained by a manufacturer who chooses a partial revocation list from the revocation pool to store in the memory of the cartridge. The device stores its own revocation list, informs the manufacturer of cartridges which have been used and checks when a new device is installed to ensure a cloned replacement is not being used. The partial revocation list distributes enough revocation information to devices to statistically impair the cartridge yield of a cloning operation. | 12-09-2010 |
20110268270 | Method of Public Key Generation - A potential bias in the generation of a private key is avoided by selecting the key and comparing it against the system parameters. If a predetermined condition is attained it is accepted. If not it is rejected and a new key is generated. | 11-03-2011 |
20120084243 | Malleable Access Decision Processing And Ordering - An electronic device is provided. The electronic device comprises a memory, a processor, a rules data base stored in the memory, a context data base stored in the memory, and a rules engine stored in the memory. The rules data base comprises a plurality of access rules defined by different stakeholders. The context data base comprises contextual information comprising at least one of a relationship of the electronic device to a communication service plan owner associated with the electronic device, a work schedule associated with a user of the electronic device, a communication service account status, an entertainment service account status, and a gaming service account status. The rules engine application, when executed by the processor, grants access to a requested communication service based on applying the rules stored in the rules data base in accordance with the contextual information. | 04-05-2012 |
20120131322 | System and Method for Authenticating a Gaming Device - A method and system are provided for authenticating and securing an embedded device using a secure boot procedure and a full non-volatile memory encryption process that implements Elliptic Curve Pinstov-Vanstone Signature (ECPV) scheme with message recovery on a personalized BIOS and master boot record. The signature includes code that is recovered in order to unlock a key that is in turn used to decrypt the non-volatile memory. The use of ECPVS provides an implicit verification that the hardware is bound to the BIOS since the encrypted memory is useless unless properly decrypted with the proper key. | 05-24-2012 |
