Link-by-link Encryption

Link-by-link Encryption is a stepwise protection of data that flows between two points in a network, provided by encrypting data separately on each network link, that is, by encrypting data when it leaves a host or subnetwork relay and decrypting when it arrives at the next host or relay. Each link can use a different key or even a different algorithm.
