Abstract

All-or-Nothing Encryption is a useful technique which can heighten the security of block ciphers. It can also be used to design faster symmetric-key cryptosystems, by decreasing the number of required encryption operations at run-time. An open problem in the literature regards the speed of all-or-nothing encryption, which we address in this paper by combining two techniques from the literature, forming a new all-or-nothing mode of operation. Trade-offs in the implementation of this design are considered, and theoretical proofs of security are provided.
