An Application of Quasigroups in All-Or-Nothing Transform
Stelios I. Marnas, Lefteris Angelis, George L. Bleris · Cryptologia · 2007
All-Or-Nothing (AON) is an encryption mode for block ciphers with the property that an adversary must decrypt the entire ciphertext in order to determine any plaintext block. In this article, we present a new encryption scheme with the AON property, based on operations defined by quasigroups. The proposed procedure is a reliable and secure preprocessing step to any other common encryption mode, aiming to slow down the brute force searches against block ciphers.
