  • Patent number: 8239673
    Abstract: A device (200, 2200) for improved security includes a processor (200) and a secure writeable memory (2245) coupled to said processor (200) and including code (2240) to download a loadable security kernel to the processor (200), authenticate the loadable security kernel, and transfer the kernel so that the kernel begins at a predetermined address inside the secure writeable memory (2245) only if the authentication is successful. A process (2400) of manufacturing a target communication device (2310) having a memory space having a secure writable portion (2245) of the memory space, the manufacturing process (2400) using a host machine (2330). The manufacturing process (2400) includes downloading (2540) the loadable security kernel from the host machine (2330) to the memory space at the target (2310). The loadable security kernel has a flashing entry point.

  • Publication number: 20120110659
    Abstract: An integrated circuit (122) includes an on-chip boot ROM (132) holding boot code, a non-volatile security identification element (140) having non-volatile information determining a less secure type or more secure type, and a processor (130). The processor (130) is coupled to the on-chip boot ROM (132) and to the non-volatile security identification element (140) to selectively execute boot code depending on the non-volatile information of the non-volatile security identification element (140). Other technology such as processors, methods of operation, processes of manufacture, wireless communications apparatus, and wireless handsets are also disclosed.

  • Patent number: 8032764
    Abstract: An electronic device (1640) includes a non-volatile store (1620) holding a plurality of encrypted sub-applications (SubApp n), and application-specific identifications (ASIDs) to respectively identify the encrypted sub-applications (SubApp n), and at least one wrapper having a representation of code to call (2220) a function (KPPA2) and supply a said application-specific identification (ASID) to the called function (KPPA2) to determine a storage location (UU) and access (2250) the storage location (UU) for contents and to call (2260) for decryption of the encrypted sub-application (SubApp n) using the contents of the storage location (UU) as a key; and a processor (1660) coupled to said non-volatile store (1620) and operable to access the representation of code and execute the code (2220, 2260). Various electronic devices, information products, processes of manufacture, and apparatus are disclosed and claimed.

  • Publication number: 20110162082
    Abstract: An electronic circuit includes a more-secure processor having hardware based security for storing data. A less-secure processor eventually utilizes the data. By a data transfer request-response arrangement between the more-secure processor and the less-secure processor, the more-secure processor confers greater security of the data on the less-secure processor. A manufacturing process makes a handheld device having a storage space, a less-secure processor for executing modem software and a more-secure processor having a protected application and a secure storage. A manufacturing process involves generating a per-device private key and public key pair, storing the private key in a secure storage where it can be accessed by the protected application, combining the public key with the modem software to produce a combined software, signing the combined software; and storing the signed combined software into the storage space.
