Group ring cryptography

چکیده
Cryptographic systems are derived using units in group rings. Combinations of types of units in group rings give units not of any particular type. This includes cases of taking powers of units and products of such powers and adds the complexity of the discrete logarithm problem to the system. The method enables encryption and (error-correcting) coding to be combined within one system. These group ring cryptographic systems may be combined in a neat way with existing cryptographic systems, such as RSA, and a combination has the combined strength of both systems. Examples are given.

A Provably Secure Ring Signature Scheme in Certificateless Cryptography
Ring signature is a kind of group-oriented signature. It allows amember of a group to sign messages on behalf of the group withoutrevealing his/her identity. Certificateless public key cryptography wasfirst introduced by Al-Riyami and Paterson in Asiacrypt 2003. Incertificateless cryptography, it does not require the use of certificatesto guarantee the authenticity of users’...
متن کاملA New Ring-Based SPHF and PAKE Protocol On Ideal Lattices
emph{ Smooth Projective Hash Functions } ( SPHFs ) as a specific pattern of zero knowledge proof system are fundamental tools to build many efficient cryptographic schemes and protocols. As an application of SPHFs, emph { Password - Based Authenticated Key Exchange } ( PAKE ) protocol is well-studied area in the last few years. In 2009, Katz and Vaikuntanathan described the first lattice-based ...
متن کاملCertificateless Ring Signatures
Ring signature scheme is a cryptographic construct that enables a signer to sign on behalf of a group of n different people such that the verifier can only ensure someone in the group signed, but not exactly whom. Ring signatures are utilized in many security applications. It is tricky to deploy multi-user cryptographic construct due to the complexity involved by certificates. Specifically, rin...

متن کاملInsecurity of a Certificate-free Ad Hoc Anonymous Authentication
The ring signature scheme is a simplified group signature scheme for no manager while preserving unconditionally anonymous of the signer. Certificateless cryptography is introduced for eliminating the use of certificates in Public Key Infrastructure and solving the key-escrow problem in ID-based cryptogratography. Recently, Qin et al. proposed the first RSA-based certificateless ring signature ...
