What is Superencryption?

Superencryption is a way of securing data by combining two or more cryptographic algorithms; it is the act of encrypting an already encrypted message.


What is it: Superencryption, also known as cascade encryption, cascade ciphering, multiple encryption, or superencipherment, is the application of a series of multiple encryption processes to a text.

What it does: Superencryption re-encrypts results from an encryption algorithm to create a stronger, more secure ciphertext. This makes the original plaintext much harder and more time-consuming to decrypt.

Why it matters: The importance of data security cannot be overstated. Up-and-coming measures such as superencryption present an added layer of protection for securing data in a near-impenetrable manner.

What to do about it: Although superencryption appears more secure than standard, single-algorithm encryption, it is still being developed and tested. Organizations need to research new encryption approaches carefully, and consider how each may help protect against cyber threats, data theft, and other cryptographic attacks.
