Abstract
Apparatus and method load, authenticate, and/or execute authenticated code modules stored in a private memory.
Claims34
A method comprising
- transferring an authenticated code module to a private memory;
- and
- executing the authenticated code module stored in the private memory in response to determining that the authenticated code module stored in the private memory is authentic.
A computing device, comprising
- a chipset;
- a memory coupled to the chipset;
- a machine readable medium interface to receive an authenticated code module from a machine readable medium;
- a private memory coupled to the chipset;
- and
- a processor to transfer the authenticated code module from the machine readable medium interface to the private memory and to authenticate the authenticated code module stored in the private memory.
3 more elements
A computing device, comprising
- a chipset;
- a machine readable medium interface to receive an authenticated code module from a machine readable medium;
- and
- a processor coupled to the chipset via a processor bus, the processor to transfer the authenticated code module from the machine readable medium interface to a private memory of the processor and to authenticate the authenticated code module stored in the private memory.
1 more element
A computing device, comprising
- a memory;
- a chipset comprising a memory control that defines a portion of the memory as private memory;
- a machine readable medium to receive an authenticated code module from a machine readable medium;
- and
- a processor to transfer the authenticated code module from the machine readable medium interface to the private memory and to authenticate the authenticated code module stored in the private memory.
2 more elements
A machine readable medium comprising one or more instructions that in response to being executed result in a computing device
- transferring an authenticated code module to a private memory associated with a processor;
- and
- executing the authenticated code module stored in the private memory in response to determining that the authenticated code module stored in the private memory is authentic.
