Abstract
An electronic system with security functionality that optimizes performance of the electronic system during cryptographic operations. In one embodiment, the electronic system includes a chipset having circuitry to perform bulk cryptographic operations and a circuitry physically removed from the chipset to control and manage operations of the chipset.
Claims19
An electronic system comprising:
- a memory element to store a key recovered from a selected header portion of incoming information and a priority value associated with the key, the priority value establishing a priority for selecting to overwrite the key when loading a new key;
- and
- a chipset coupled to the memory element, the chipset including circuitry to perform a bulk cryptographic operation on a content portion of the incoming information based on the key recovered from the selected header portion of the incoming information.
An electronic system comprising:
- at least one peripheral device;
- a chipset in communication with the at least one peripheral device, the chipset including circuitry to perform a bulk cryptographic operation on a content portion of incoming information provided by the at least one peripheral device based on a key recovered from a header portion of the incoming information;
- and
- a first storage element coupled to the chipset to store the key and a priority value associated with the key, the priority value establishing a priority for selecting to overwrite the key when loading a new key.
1 more element
A chipset comprising:
- circuitry to decrypt a predetermined header portion of incoming information to recover a key;
- a first storage element to store the key, the first storage element including a plurality of storage entries, each of the plurality of storage entries including a key field to store a key and a priority field to store a priority value associated with the key, the priority value establishing a priority for determining which storage entries to overwrite when loading new keys;
- and
- a cryptographic engine to perform bulk cryptographic operations on a content portion of the incoming information using the key.
