Abstract:
The authentic key exchange protocol is widely used in secure transfer protocols such as TLS and SSL. Compared to explicit authentication, implicit authentication have significant advantages in terms of efficiency and bandwidth. Representative examples are HMQV, OAKE, NAXOS, Okamoto-AKE, and the like. However, the research of implicit authentication key exchange protocol is relatively independent and is not suitable for extension to anti-quantum security problems such as lattice and hyper-singular homology. In view of the problems, the speaker proposes a simple non-interactive dual-key encapsulation mechanism and provides an authentication key exchange protocol framework based on it, which not only summarized the existing well-known authentication key exchange protocol (AKE), but also leads to highly efficient AKE with post-quantum security.
