Link Encryption will encrypt the link on which data transmission is carried on, but the hacker can still hack your data once it's reached to your computer.

End to End communication encrypt data from source program to destination program thus its more secure.

Link encryption is an approach to communications security that encrypts and decrypts all traffic at each end of a communications line (e. G. A teleprinter circuit or the line between two network switches). It contrasts with end-to-end encryption where messages are encrypted by the sender at the point of origin and only decryption by the intended receiver. Link encryption offers a couple of advantages:

Encryption is automatic so there is less opportunity for human error.

If the communications link operates continuously and carries an unvarying level of traffic, link encryption defeats traffic analysis.

Its an approach that encrypts and decrypts all traffic at the end of communication line.

Can anybody explain what is link encryption ?
