n-QUASIGROUP CRYPTOGRAPHIC PRIMITIVES: STREAM CIPHERS
نویسنده
چکیده
In this paper we present two new n-quasigroup stream ciphers based on new n-quasigroup encryption scheme. Also, we present a practical implementation of these ciphers that has very good cryptographic properties. The implementation is based on a design concept of mixing two ”incompatible” group operations on the set Z28 .

On some quasigroup cryptographical primitives
Using Vojvoda approach [34] we demonstrate that cryptographical primitives proposed in [26] are vulnerable relative to chosen ciphertext attack and chosen plaintext attack. We develop proposed in [31] modifications and add some new modifications of known quasigroup based stream ciphers [19, 26]. Systems of orthogonal n-ary groupoids are used. 2000 Mathematics Subject Classification: 20N05, 20N1...
متن کاملClassification of Quasigroup-structures with respect to their Cryptographic Properties
Computationally simple but cryptographically strong ciphers play an important role for efficient Computer Security tasks. It is suggested in (Knapskog, 2008) that there is a need for simple cryptographic primitives to implement security in an environment with end users connected with terminals having limited storage and processing power. Constructing ciphers using the algebraic structures of Qu...
متن کاملLightweight 4x4 MDS Matrices for Hardware-Oriented Cryptographic Primitives
Linear diffusion layer is an important part of lightweight block ciphers and hash functions. This paper presents an efficient class of lightweight 4x4 MDS matrices such that the implementation cost of them and their corresponding inverses are equal. The main target of the paper is hardware oriented cryptographic primitives and the implementation cost is measured in terms of the required number ...
متن کاملStream ciphers and the eSTREAM project
Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.
متن کاملRecent Developments in the Design of Conventional Cryptographic Algorithms
This paper examines proposals for three cryptographic primitives: block ciphers, stream ciphers, and hash functions. It provides an overview of the design principles of a large number of recent proposals, which includes the global structure, the number of rounds, the way of introducing non-linearity and diffusion, and the key schedule. The software performance of about twenty primitives is comp...
