Title:
Context-Dependent Threshold Decryption and its Applications
Authors: Dan Boneh, Benedikt Bünz, Kartik Nayak, Lior Rotem, Victor Shoup
Abstract:We initiate the study of high-threshold public-key decryption, along with an enhanced security feature called context-dependent decryption.
Our study includes definitions, constructions, security proofs, and applications.
The notion of high-threshold decryption has received almost no attention in the literature. The enhanced security feature of context-dependent encryption is entirely new, and plays an important role in many natural applications of threshold decryption.
