Threshold Encryption with Silent Setup

ePrint Report: Threshold Encryption with Silent Setup

Sanjam Garg, Dimitris Kolonelos, Guru-Vamsi Policharla, Mingyuan Wang

We build a concretely efficient threshold encryption scheme where the joint public key of a set of parties is computed as a deterministic function of their locally computed public keys, enabling a silent setup phase. By eliminating interaction from the setup phase, our scheme immediately enjoys several highly desirable features such as asynchronous setup, multiverse support, and dynamic threshold.
Prior to our work, the only …
