On the Relations Between Non-Interactive Key Distribution, Identity-Based Encryption and Trapdoor Discrete Log Groups

Kenneth G. Paterson and Sriramkrishnan Srinivasan

Abstract

We investigate the relationships between identity-based non-interactive key distribution and identity-based encryption. We provide constructions for these schemes that make use of general trapdoor discrete log groups. We then investigate the schemes that result in two concrete settings, obtaining new, provably secure, near-practical identity-based encryption schemes.

Note: This is the final accepted version of the paper.
