Symmetric ciphers are generally acclimated
to accomplish added cryptographic primitives than aloof encryption
.
Encrypting a bulletin does not agreement that this bulletin is not afflicted while encrypted. Hence generally a bulletin affidavit cipher is added to a ciphertext to ensure that changes to the ciphertext will be acclaimed by the receiver. Bulletin affidavit codes can be complete from symmetric ciphers (e.g. CBC-MAC
).
However, symmetric ciphers additionally can be
acclimated for non-repudiation purposes by ISO 13888-2 standard.
Another appliance is to body assortment functions from block ciphers. See one-way compression action for descriptions of several such methods.
