| Abstract(in English) | Oblivious automata evaluation is the protocol that allows two parties, a server holding a description of a finite state automaton M and a client holding a string x, to determine whether M accepts x, without revealing M or x to the other party. Oblivious Transfer (OT)-based constructions of the protocol which have been known so far have a drawback in terms of the message size transferred from the server to the client. In this paper, new approach to reduce the size of messages in the OT is presented by avoiding duplicated message transfer using structural characteristics of finite state automaton. |
