Abstract

Wireless communications require the cryptography system which satisfies a opposite purpose as safety and efficiency. In this paper we proposed the efficient key distribution system satisfying in wireless communication using escrow in order to satisfy the requirements. We supplemented the key recovery function to prevent side effects of cryptography and it is possible to check verification. Also, transmitted information is a little so that the system is efficient. The proposed key recovery method can be applicable to various application fields.

무선 통신은 환경적인 특성 때문에 안전성과 효율성이라는 상반된 목적을 만족시킬 수 있는 암호 시스템을 요구한다 본 논문에서는 이를 만족시킬 수 있도록 위탁 방식을 이용하여 무선 통신상의 효율적인 키 분배 및 키 복구 시스템을 제안하였다. 제안하는 시스템은 암호의 역기능을 방지하기 위하여 요구되는 키 복구 기능을 추가하였으며, 키 복구 정보에 대한 유효성 검사가 가능하다. 또한 전송되는 정보가 적어 효율적이다. 본 논문에서 제안한 키 복구 방식은 송수신자 양쪽에서 동일한 방법을 사용하므로 다양한 응용 분야에 적용될 수 있다.
