link encryption

The decryption and re-encryption of confidential data at various router or switching junctions throughout the transmission path. For example, a transmission from Boston to Phoenix is encrypted in Boston, decrypted in Atlanta, re-encrypted (perhaps with a different algorithm) in Atlanta and decrypted in Phoenix. Link encryption creates a greater risk of a security breach. Contrast with end-to-end encryption.
