Patent ID: 7386723

Claim:
A method of securing and compressing a network packet, comprising: applying a first robust header compression scheme to the network packet, the network packet comprising a first packet header, a second packet header and a payload, the first robust header compression scheme being applied to the first packet header to generate an end-to-end compressed packet header, the end-to end compressed packet header, the second packet header and the payload together comprising an end-to-end compressed network packet; encrypting the end-to-end compressed network packet, by adding an encryption header to the end-to-end compressed network packet to generate an encrypted end-to-end compressed network packet, the encrypted end-to-end compressed network packet comprising the encryption header, the end-to-end compressed packet header, the second packet header and the payload; and applying a second robust header compression scheme to the encryption header, the end-to-end compressed packet header and the second packet header in the encrypted end-to-end compressed network packet to generate a hop-by-hop compressed network packet.
