Abstract
The present disclosure relate to exchanging information between a start node and an end node. Based on the information session keys for a connection comprising the start node, the end node, and at least one intermediate node are established. The session keys include a data encryption session key and a Message Authentication Code (MAC) session key. The data is encrypted using the data encryption session key at the start node. MAC is generated using the MAC session key. The encrypted data is relayed, via the at least one intermediate node, from the start node to the end node without the at least one intermediate node re-encrypting the data.
