– We have designed a new class of public key algorithms based on quasigroup string transformations using a specific class of quasigroups called multivariate quadratic quasigroups (MQQ). Our public key algorithm is a bijective mapping, it does not perform message expansions and can be used both for encryption and signatures. The public key consist of n(More)
The need of true random number generators for many purposes (ranging from applications in cryptography and stochastic simulation , to search heuristics and game playing) is increasing every day. Many sources of randomness possess the property of stationarity. However , while a biased die may be a good source of entropy, many applications require input in(More)
This document contains the Intellectual Property Statement and the technical description of the MQQ-SIG-a new public key digital signature scheme. The complete scientific publication covering the design rationale and the security analysis will be given in a separate publication. MQQ-SIG consists of n − n 4 quadratic polynomials with n Boolean variables(More)
Security is one of the issues in trend in networking domain. Obtaining a reliable method for providing secure communication is one of the basic tasks in this area. We implemented a solution by using a Quasigroup Enciphering method with almost public key as a new concept explained in detail in this paper. This Quasigroup Enciphering method is based on using(More)
SMS (Short Message Service) is a widely used service for brief communication. Occasionally the data sent using SMS services is confidential in nature and is desired not to be disclosed to a third party. In this paper an application for sending encrypted SMS messages using cryptographic methods based on theory of quasigroups is proposed. The encryption(More)
