Abstract

Mobile computing system requires both precise identification and secure authentication scheme on remote mobile entities, which is based on the distributed mobile node. In this paper, existing discrete logarithm based $Schnorr^{[7]}$ like entity authentication schemes are improved by the analysis of performance and security on the hi-directional interactive proofs. And $EIGamal^{[14]}$ like efficient authentication schemes are also proposed. Then, these are enhanced with oblivious transfer based mono directional authentication schemes based on trusted third party for applying to the mobile agent based computing systems. Therefore, proposed schemes provide compatible performance and safety on mobile entity authentication processes.

이동 노드와 같은 분산 이동 객체를 사용한 이동 컴퓨팅 시스템은 원격 이동 엔티티에 대한 정확하고 안전한 신분 확인 및 신원 검증 과정이 필요하다. 본 연구에서는 기존의 대화형 기반 이동 노드 인증 기법에 대한 성능 분석 및 안전성 분석을 통해 이산 대수 기법에 기반한 Schnorr형 인증 기법을 개선하고 ElGamal 기법을 변형 발전시킨 효율적 인증 기법을 제시하였다. 제안한 기법은 이동 노드 서버에 기반한 컴퓨팅 시스템에 적용하기 위해 불확정 전송 기반 비대화형 인증 기법으로 분산 이동 컴퓨팅 환경에서의 노드 인증에 적합한 성능과 안전성을 제공한다.
