초록

이 논문에서는 래티스(Lattice)의 CVP (Closest Vector Problem)에 기반한 영지식 증명 기반의 인증프로토콜을 제안한다. CVP를 이용해서 암호시스템을 설계할 때 흔히 사용하는 길이가 짧은 기저벡터를 트랩도어 또는 비밀키로 사용하지 않는 프로토콜로서 의의를 가지며, 프로토콜의 설계가 단순하고 안전성 증명도 쉬워진다. 제안한 프로토콜의 안전성을 completeness, soundness, simulatability로 증명한다.

Abstract

In this paper, we propose a new closest vector problem based interactive proof that is useful for authentication. Contribution of this paper is that the proposed protocol does not use a special form of a lattice, but a general lattice, which makes the protocol design very simple and easy to be proved. We prove its security in terms of completeness, soundness, simulatability.
