MODEL OF E-MAILING SYSTEM USING POLYNOMIALS OVER NONCUMMUTATIVE DIVISION SEMIRING

[摘要] In this paper we show a model of e-mailing system using polynomials over non-commutative Division semiring for internet communication. It is the model of a real-life secure mailing system. In this model, a sender can send a secret message even to a unacquainted person in an anonymous way. The users of this model are assumed to be may or may not be the members of a closed organization.
