Abstract
A decentralized method for IPSec processing in virtual environments includes assigning a unique identifier to each of a set of compute nodes. Each compute node can emulate one or more virtual machines that generate IP packets for forwarding over a network (e.g., the Internet). An IP packet, received from a trusted source at a compute node, is encrypted and a trailer is appended to the encrypted packet. The trailer includes the unique identifier of the compute node. The encrypted packet with appended trailer is forwarded to a secure gateway that can perform an anti-replay check using stored parameters corresponding to the unique identifier in the trailer. In inbound processing, the unique identifier is inserted into a trailer appended to an encrypted packet by the security gateway and a VPN server directs the incoming encrypted packet to the appropriate compute node for forwarding to the virtual machine.
