Abstract: An architecture and associated methods and devices are described in which a first selectable data path may be associated with a first port operating at a first data rate, a second selectable data path may be associated with a second port operating at a second data rate, and a third selectable data path may be associated with a third port operating at a third data rate that is higher than the first data rate and the second data rate. A plurality of security engines may be included which may be configurable to provide cipher key-based security for data associated with the first port and the second port using the first selectable path and the second selectable path, respectively, and configurable to provide cipher key-based security of data associated with the third port using the third selectable data path.
