TRANSPARENT IPSEC PROCESSING INLINE BETWEEN A FRAMER AND A NETWORK COMPONENT

摘要

A method and apparatus for transparent processing of IPsec network traffic by a security processor in line between a framer and a network processor. Security processor parses packet header and tail information to determine if encryption or decryption is required. After encryption or decryption is completed packet header and tail information is modified to reflect the changes in the packet such as length of the packet. The modified packet is then passed on to the network processor or framer.
