link encryption
(I) Stepwise protection of data that flows between two points in a
network, provided by encrypting data separately on each network
link, i.e., by encrypting data when it leaves a host or subnetwork
relay and decrypting when it arrives at the next host or relay.
Each link may use a different key or even a different algorithm.
