Abstract
A point-to-point Virtual Private Network (VPN) tunnel is established for facilitating fully cloaked transmission of a data packet from a source endpoint device to a destination endpoint device. The data packet includes a payload portion, an inner header, and an outer header. An ‘end-to-end key’, a ‘next-hop-destination key’ and a plurality of ‘next-hop’ keys are calculated. The end-to-end key is used at the source endpoint device and the destination endpoint device respectively to encrypt and decrypt the payload portion. The next-hop keys are used to encrypt the inner header during the hop-to-hop communication from one intermediary node to another, along the incrementally constructed path connecting the source endpoint device with the destination endpoint device. The encryption of the payload portion is maintained throughout the hop-to-hop communication regardless of the number of intermediary nodes traversed by the data packet en route to the destination endpoint device.
