Shared security transform device, system and methods

摘要

A shared security transform device is described as being usable to couple to a plurality of nodes via a common switch comprises control logic and memory coupled to the control logic. The memory may contain security information. The shared security transform device receives packets from any of the nodes via the switch and, using a value in the packets, retrieves security handling instructions to determine whether or not to apply a security transform to the packet. If a security transform is to be applied to the packet, the shared security transform device may determine which of a plurality of transforms is to be applied to the packet.
