Lattice-based Cryptography for IoT in A Quantum World: Are We Ready?
Quantum Safe cryptography Post quantum cryptography IoT security
2019/6/12
The impending realization of scalable quantum computers has led to active research in Post Quantum Cryptography (PQC). The challenge is harder for embedded IoT (edge) devices, due to their pervasive d...
Concretely-Efficient Zero-Knowledge Arguments for Arithmetic Circuits and Their Application to Lattice-Based Cryptography
zero-knowledge lattice cryptography MPC
2019/5/23
In this work we present a new interactive Zero-Knowledge Argument of knowledge for general arithmetic circuits. Our protocol is based on the ``MPC-in-the-head''-paradigm of Ishai et al. (STOC 2009) an...
