A high-speed key exchange multi-core SoC architecture for IPSec real-time Internet traffic

This paper presents a scalable and flexible multi-core SoC architecture for high-speed key exchange for emerging IP security systems. Novel approaches are proposed for HMAC authentication block parallelization, distributed key handling and a pipelined block cipher design that allows feedback encryption modes. This improves upon previous state-of-the-art designs for IPSec, creating an architecture suitable for delivering emerging secure high-speed streaming applications via the Internet.
