Non-Interactive Key Exchange from Identity-Based Encryption
Olivier Blazy, Céline Chevalier · 2018
Since the seminal work of Diffie and Hellman [19], Non-Interactive Key Exchange (NIKE) has become one of the fundamental problems of modern cryptography, but additional security requirements have led to elaborated ad-hoc constructions, which often lack simplicity in their design. In particular, Identity-Based NIKE is still a major problem with few available constructions, and those ad-hoc constructions do not give a lot of insight on what is required to be able to achieve such a NIKE scheme only based on the identity (and not relying on the public-key setting).
