This paper describes a unique way to encrypt communications utilizing a multi-phase process that minimizes the complexity of key exchange. This solution also takes advantage of a co-processor within the encrypting Network Interface Card (eNIC) to perform the encryption, freeing the main processor for other tasks. It also utilizes a protocol between eNIC to eNIC which steers the message flow in a hierarchical fashion, such that a sender node only needs to know a narrow subset of gateway nodes public keys. In the current version of a three layer hierarchical implementation, we propose an intra-LAN, intra-WAN and inter-WAN gateway structure.
