Explanation

When using link encryption, packets have to be decrypted at each hop and encrypted again. Information staying encrypted from one end of its journey to the other is a characteristic of end-to- end encryption, not link encryption. Link Encryption vs. End-to-End Encryption Link encryption encrypts the entire packet, including headers and trailers, and has to be decrypted at each hop. End-to-end encryption does not encrypt the IP Protocol headers, and therefore does not need to be decrypted at each hop.
