On some quasigroup cryptographical primitives
نویسندگان
چکیده
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, 20N15, 94A60

Resistance to Statistical Attacks of Parastrophic Quasigroup Transformation
The resistance to statistical kind of attacks of encrypted messages is a very important property for designing cryptographic primitives. In this paper, the parastrophic quasigroup PE-transformation, proposed elsewhere, is considered and the proof that it has this cryptographic property is given. Namely, it is proven that if PE-transformation is used for design of an encryption function then aft...
متن کاملAn Application of Ternary Quasigroup String Transformations
One of the most popular current trends in cryptography is the research for new approaches for designing cryptographic primitives. Using the algebraic structures for constructing such primitives is studied by many researches. Our investigation is focused on finding ternary quasigroups with good properties for designing cryptographic primitives. In this paper we define ternary quasigroup transfor...
متن کاملn-QUASIGROUP CRYPTOGRAPHIC PRIMITIVES: STREAM CIPHERS
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 .
متن کاملStream cipher based on quasigroup string transformations in ZZp
In this paper we design a stream cipher that uses the algebraic structure of the multiplicative group ZZp (where p is a big prime number used in ElGamal algorithm), by defining a quasigroup of order p− 1 and by doing quasigroup string transformations. The cryptographical strength of the proposed stream cipher is based on the fact that breaking it would be at least as hard as solving systems of ...
متن کاملTesting Quasigroup Identities using Product of Sequence
Non-associative quasigroups are well known combinatorial designs with many different applications. Many cryptographic algorithms based on quasigroups primitives have been published. There are several classifications of quasigroups based on their algebraic properties. In this paper we propose a new classification of quasigroups based upon strings (product elements) obtained by a product of a seq...
