AKE(인증된 키 교환)는 여러 당사자 간에 공통 세션 키를 공유하는 암호화 프로토콜입니다. 일반적으로 PKI 기반 AKE 체계는 세션 키의 비밀성과 상호 인증을 보장하도록 설계되었습니다. 그러나 실제로는 Tor, Riffle과 같은 익명 네트워크에서는 상호 인증이 바람직하지 않거나 인터넷과 같은 사용자 수준의 인증서 관리로 인해 달성하기 어려운 경우가 많습니다. Goldberget al. 클라이언트만이 서버를 인증할 수 있도록 하여 클라이언트의 익명성을 보장하는 익명 일방적 AKE 모델을 공식화하고 구체적인 방식을 제안했습니다. 그러나 기존의 익명 일방적 AKE 체계는 무작위 오라클 모델에서만 안전한 것으로 알려져 있습니다. 본 논문에서는 무작위 오라클 모델과 표준 모델에서 각각 익명의 단측 AKE의 일반적인 구성을 제안합니다. 우리의 구성을 통해 표준 모델의 동질성으로부터 최초의 양자 후 익명 단방향 AKE 체계를 구성할 수 있습니다.

Abstract: Authenticated Key Exchange (AKE) is a cryptographic protocol to share a common session key among multiple parties. Usually, PKI-based AKE schemes are designed to guarantee secrecy of the session key and mutual authentication. However, in practice, there are many cases where mutual authentication is undesirable such as in anonymous networks like Tor and Riffle, or difficult to achieve due to the certificate management at the user level such as the Internet. Goldberg et al. formulated a model of anonymous one-sided AKE which guarantees the anonymity of the client by allowing only the client to authenticate the server, and proposed a concrete scheme. However, existing anonymous one-sided AKE schemes are only known to be secure in the random oracle model. In this paper, we propose generic constructions of anonymous one-sided AKE in the random oracle model and in the standard model, respectively. Our constructions allow us to construct the first post-quantum anonymous one-sided AKE scheme from isogenies in the standard model.
