Public Key Exchange Using Matrices Over Group Rings

We offer a public key exchange protocol in the spirit of Diffie-Hellman, but weuse (small) matrices over a group ring of a (small) symmetric group as the platform. This“nested structure” of the platform makes computation very efficient for legitimate parties.We discuss security of this scheme by addressing the Decision Diffie-Hellman (DDH) andComputational Diffie-Hellman (CDH) p...

Public Key Protocols over the Ring E

In this paper we use the nonrepresentable ring E (m) p to introduce public key cryptosystems in noncommutative settings and based on the Semigroup Action Problem and the Decomposition Problem respectively.

COTORSION DIMENSIONS OVER GROUP RINGS

Let $Gamma$ be a group, $Gamma'$ a subgroup of $Gamma$ with finite index and $M$ be a $Gamma$-module. We show that $M$ is cotorsion if and only if it is cotorsion as a $Gamma'$-module. Using this result, we prove that the global cotorsion dimensions of rings $ZGamma$ and $ZGamma'$ are equal.

Key exchange protocols over noncommutative rings. The case of

In this paper we introduce some key exchange protocols over noncommutative rings. These protocols use some polynomials with coefficients in the center of the ring as part of the private keys. We give some examples over the ring End(Zp × Zp2), where p is a prime number. We also give a security analysis of the proposed protocols and conclude that the only possible attack is by brute force.

GENERALIZED GORENSTEIN DIMENSION OVER GROUP RINGS

Let $(R, m)$ be a commutative noetherian local ring and let $Gamma$ be a finite group. It is proved that if $R$ admits a dualizing module, then the group ring $Rga$ has a dualizing bimodule as well. Moreover, it is shown that a finitely generated $Rga$-module $M$ has generalized Gorenstein dimension zero if and only if it has generalized Gorenstein dimension zero as an $R$-module.
