SECURITY PROCESSING ENGINES, CIRCUITS AND SYSTEMS AND ADAPTIVE PROCESSES AND OTHER PROCESSES

摘要

An electronic circuit (200) includes one or more programmable control-plane engines (410, 460) operable to process packet header information and form at least one command, one or more programmable data-plane engines (310, 320, 370) selectively operable for at least one of a plurality of cryptographic processes selectable in response to the at least one command, and a programmable host processor (100) coupled to such a data-plane engine (310) and such a control-plane engine (410). Other processors, circuits, devices and systems and processes for their operation and manufacture are disclosed.

1. A packet-processing electronic subsystem comprising:
a first data interface having an input for accepting first streaming data and having an output; a second data interface having an input for accepting second streaming data and having an output; a third data interface having an output for egress of third streaming data and having an input; a fourth data interface having an output for egress of fourth streaming data and having an input, the first, second, third, and fourth data interfaces being separate from one another; scheduler circuitry having inputs coupled to the outputs of the first and second interfaces, having outputs coupled to the inputs of the third, and fourth data interfaces, and including a packet memory, the scheduler circuitry having a security context cache interface, a packet header processor interface, an authentication interface, and an air cipher interface; a security context cache coupled to the security context cache interface of the scheduler circuitry and including a cache controller and cache storage for a security context; a packet header processor coupled to the packet header processor interface of the scheduler circuitry; an authentication module coupled to the authentication interface of the scheduler circuitry; and an air cipher module coupled to the air cipher interface of the scheduler circuitry, the air cipher module including processor and control circuitry.
