Abstract
A security subsystem is provided with at least a first security engine, a first set of registers and a control portion to perform a first security operation for each of a first number of data blocks of each of a first number of data segments of a first data object. In one embodiment, the security subsystem is provided with two security engines and two sets of registers to respectively perform the first security operation and a second security operation for the first data object and a similarly constituted second data object. In one embodiment, the first and second security operations are DES and hashing operations. In one embodiment, the multi-method security subsystem is embodied in a multi-service system-on-chip.
