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

Less-secure processors, integrated circuits, wireless communications apparatus, methods for operation thereof, and methods for manufacturing thereof

Systems and methods for providing a battery modulewith secure identity information and authentication of the identity of the batteryby a host. In one embodiment, the system for providing a battery module with secure identity information includes: (1) a tamper resistant processing environmentlocated within the battery moduleand (2) a key generator configured to generate a key based on an identity of the battery moduleand cause the key to be stored within the tamper resistant processing environment

Host/battery with public/private busses, public memory, processor, and private memory

Less-secure processors, integrated circuits, wireless communications apparatus, methods and processes of making

Authentication with battery and host programmed with shared identity key

An electronic circuitincludes 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 (). Other processes of manufacture, processes of operation, circuits, devices, wireless and wireline communications products, wireless handsets and systems are disclosed and claimed.

System and method for secure authentication of a 'smart' battery by a host

A device () for improved security includes a processor () and a secure writeable memory () coupled to said processor () and including code () to download a loadable security kernel to the processor (), authenticate the loadable security kernel, and transfer the kernel so that the kernel begins at a predetermined address inside the secure writeable memory () only if the authentication is successful. A process () of manufacturing a target communication device () having a memory space having a secure writable portion () of the memory space, the manufacturing process () using a host machine (). The manufacturing process () includes downloading () the loadable security kernel from the host machine () to the memory space at the target (). The loadable security kernel has a flashing entry point. The process also includes authenticating () the downloaded loadable security kernel received at the target (), moving () the loadable security kernel in the memory space provided the authenticating is successful (), wherein after the moving () the loadable security kernel is in the secure writable portion () of the memory space; and jumping () to a predetermined location in the secure writable portion of the memory space, the predetermined location coinciding with the flashing entry point of the security kernel as moved.
