ePrint ReportIn this work, we show that there is a more direct and more efficient way to prove that the coefficients of $s$ have a small $\ell_2$ norm which does not require an equivocation with the $\ell_\infty$ norm, nor any conversion to the CRT representation. We observe that the inner product between two vectors $ r$ and $s$ can be made to appear as a coefficient of a product (or sum of products) between polynomials which are functions of $r$ and $s$. Thus, by using a polynomial product proof system and hiding all but one coefficient, we are able to prove knowledge of the inner product of two vectors modulo $q$. Using a cheap, approximate range proof, one can then lift the proof to be over $\mathbb{Z}$ instead of $\mathbb{Z}_q$. Our protocols for proving short norms work over all (interesting) polynomial rings, but are particularly efficient for rings like $\mathbb{Z}[X]/(X^n+1)$ in which the function relating the inner product of vectors and polynomial products happens to be a ``nice'' automorphism.
The new proof system can be plugged into constructions of various lattice-based privacy primitives in a black-box manner. As examples, we instantiate a verifiable encryption scheme and a group signature scheme which are more than twice as compact as the previously best solutions.

Job PostingProject 1: (A*STAR) Developing Privacy Enhancing Digital Health Data Sharing
Supervision team: Dr M Mustafa (UoM), Dr LC Cordeiro (UoM), Dr Khin Mi Mi Aung (I²R)
Project 2: (A*STAR) Secure Sharing of Dynamic Data via Privacy-Preserving Distributed Learning Framework
Supervision team: Dr M Mustafa (UoM), Dr LC Cordeiro (UoM), Dr Teo Sin Gee (I²R)
Both projects will advance the state-of-the-art machine learning techniques by developing advanced privacy enhancing technologies utilising the properties of differential privacy, secure multiparty computation and homomorphic encryption. They are part of the joint PhD programme between University of Manchester (UoM) and A*STAR institutions in Singapore, e.g., Institute for Infocomm Research (I²R). The successful applicants will be hosted by both organisations: Year 1 & 4 at UoM in the UK and Year 2 & 3 at I²R in Singapore.
Application Deadline: 01 April 2022
