Abstract
Computational complexity, specifically, cryptographic operations, is removed from the IKE(Internet Key Exchange) process in a VPN gateway appliance, thereby enabling scaling of the number of datapaths that can be managed by a single IKE process. A two-tier cache configuration enables necessary cryptographic operations on packets in the gateway but does so without placing additional computational burdens on the IKE process. One cache containing security association data is local to the IPSec component of the datapath instance. The second cache is higher level and is populated by IKE with security association data upon completion of IKE Phase 2 negotiations. The local cache is searched first for security policy data and if found is used to encrypt/decrypt the data packet. If not found locally, the IKE centralized cache is searched and if found, the local cache is updated with the security association data.
