Original Abstract

Secure two-party computation allows two entities to securely calculate a common result keeping their private inputs secret. By applying this to the weak Boneh-Boyen signature, a trusted third party is able to sign the user's message (or a secret key) without knowing its content (or value). In this article, we present a C library that implements a two-party computation algorithm for generating a user's secret key that can be used in a group signature scheme. The library provides a structured output ready to be serialized and sent over a network. We also show the computational benchmarks of the implemented algorithms. The computations on the sender's side are relatively fast, which broadens the possibilities of deployment on constrained devices.
