Abstract
A method and corresponding apparatus are provided to security encapsulate an original IP datagram received from a network. It is first determined whether an IP payload of the original IP datagram is a TCP segment, UDP datagram or packet of another type of network protocol. Based on this determination, a portion of the IP payload is encrypted resulting in an encrypted payload. A security encapsulated IP packet is then formed with source IP address, destination IP address, and IP protocol field from the original IP datagram, and the encrypted payload. The security encapsulated IP packet is then provided to the network.
