Cryptographic Applications of the Duplex Construction

Mariusz Borowski

Abstract


Assured security is the desirable feature of modern cryptography. Most of moderncryptography primitives have no provably secure constructions. Their safety is defined on the basis ofwell-known in the given time cryptanalytic attacks. The duplex construction equipped with one idealpermutation and appropriate security parameters is suitable for building provably secure cryptographicprimitives. The constructions can be used for unclassified information of different sensitivity levelsprotection. Some of them can secure classified information up to the TOP SECRET level. Theapplications based on the duplex construction can be used for key wrapping, authenticated encryptionand can work as a pseudo-random bit sequence generator. They are not covered by any knownintellectual property.
