| 20080222368 | Updating Memory Contents of a Processing Device - A method of updating memory content stored in a memory of a processing device, the memory comprising a plurality of addressable memory blocks, the memory content being protected by a current integrity protection data item stored in the processing device, the method comprising determining a first subset of memory blocks that require an update, and a second subset of memory blocks that remain unchanged by said updating; calculating, as parallel processes, a first and a second integrity protection data item over the memory blocks; wherein the first integrity protection data item is calculated over the current memory contents of the first and second subsets of memory blocks; and wherein the second integrity protection data item is calculated over the current memory contents of the second subset of memory blocks and the updated memory block contents of the first subset of memory blocks. | 09-11-2008 |
| 20080261561 | Secure Soft SIM Credential Transfer - The method and apparatus described herein transfers soft SIM credentials from a transferring mobile device to a target mobile device while ensuring that only one mobile device contains active soft SIM credentials at a time. Broadly, a transferring mobile device securely transfers the soft SIM credentials to a target mobile device either directly or via a network server. Before the target mobile device receives or activates the soft SIM credentials, the transferring mobile device deactivates the soft SIM credentials to ensure that only one mobile device contains the active soft SIM credentials. | 10-23-2008 |

| 20090007275 | Method and Apparatus for Protecting SIMLock Information in an Electronic Device - The teachings herein present a method and apparatus for protecting usage restriction data that governs usage of an electronic device. A cryptographic circuit supports secure and non-secure accesses. When non-securely accessed, it is operable only to verify the stored usage restriction data, and, when securely accessed, it is operable to generate a new message authentication code for changed usage restriction data, for subsequent authentication of that data. The usage restriction data may be stored in non-secure memory and may include static and dynamic parts. One or more embodiments include a secure circuit indicating whether the device has been initialized. The cryptographic circuit outputs a message authentication code for the static part using a permanent device key from the secure circuit, only if the device has not been initialized, and outputs a message authentication code for the dynamic part as needed to support authorized changes to the dynamic part. | 01-01-2009 |

| 20090259857 | System and Method for Efficient Security Domain Translation and Data Transfer - A mobile UE includes a CPU, a secure DMA module, a secure cryptographic module, secure memory, and non-secure memory. The secure cryptographic module and secure memory allow access only by secure processes, including the secure DMA module. The CPU manages cryptographic keys and initializes DMA transfers in secure mode. The CPU executes the DMA transfers in non-secure mode. A first DMA transfer moves data encrypted in a first security domain to the secure cryptographic module, and moves clear text data to the secure memory. A second DMA transfer moves the clear text data to the secure cryptographic module, and data encrypted in a second security domain out of the secure cryptographic module. The data encrypted in the second security domain are transmitted to an external device. The secure memory protects the clear text data from being copied; only encrypted data is accessible by non-secure processes. | 10-15-2009 |
| 20090276844 | Method and Apparatus for Secure Hardware Analysis - A Hardware Analysis Module (“HAM”) embedded in an integrated circuit (IC) implements a dedicated hardware-controlled access control procedure. The secure hardware analysis features are unlocked by a key unit subject to successful completion of an access control procedure. The access control procedure prevents unlocking of the secure hardware analysis features by an unauthorized or compromised key unit by including an embedded control command in an authentication challenge sent by the HAM to the key unit during the access control procedure. | 11-05-2009 |
| 20090307478 | PLATFORM BOOT WITH BRIDGE SUPPORT - A method for booting a processing device, the processing device comprising a first and a second processing unit, the method comprising: detecting by the first processing unit, whether at least one boot configuration parameter is accessible from a non-volatile storage medium of the processing device, the at least one configuration parameter being indicative of a boot interface; if said at least one configuration parameter is available, forwarding at least a part of the detected at least one configuration parameter by the first processing unit to the second processing unit; otherwise detecting by at least one of the first and second processing units whether a boot interface is available to the processing device; booting at least the second processing unit from the indicated or detected boot interface. | 12-10-2009 |
| 20110016319 | METHOD FOR RESTRICTING ACCESS TO MEDIA DATA GENERATED BY A CAMERA - A method for restricting access to media data generated by a camera comprising: setting a non-public initial user key, KICU, in the camera, providing a user client with the initial user key, KICU, establishing an authenticated relation between the user client and the camera by sending an authentication message including information based on the initial user key, KICU, from the user client to the camera, checking if an operational user key (K | 01-20-2011 |
