개선된 `간단한 인증키 동의 (Simple Authenticated Key Agreement)` 프로토콜 = An Enhancement of Simple Authenticated Key Agreement Protocol

다국어 초록 (Multilingual Abstract)

The Diffie-Hellman Key Exchange scheme can produce a common session key between the two communicators, but its problem is that it makes a man-in-the middle attack possible. To solve problems like these, several protocols have been put forward, and the Simple Authenticated Key Agreement (SAKA) Protocol is among them. This protocol has been suggested by Seo-Sweeney, Tseng, and Ku-Wang, respectively. In this paper, we will put forward a new protocol that has been improved from all the original protocols mentioned above, but is still safe and quick to use. While the existing protocol divides the common session key production stage and the verification stage, the protocol suggested in this paper takes care of both of those stages simultaneously, therefore improving the processing performance.
