Abstract
Most lattice-based cryptographic schemes with a security proof suffer from large key sizes and heavy computations. This is also true for the simpler case of authentication protocols that are used on smart cards as a very-constrained computing environment. Recent progress on ideal lattices has significantly improved the efficiency and made it possible to implement practical lattice-based cryptography on constrained devices. However, to the best of our knowledge, no previous attempts have been made to implement lattice-based schemes on smart cards. In this article, we provide the results of our implementation of several state-of-the art lattice-based authentication protocols on smart cards and...
On Lattice-Based Provably-Secure Authentication

Abstract
Lattice-based cryptography, as one of the main candidates for post-quantum cryptography, has attracted much attention along with cryptography researchers. That is mostly due to the fact that building large-scale quantum computers is possible within coming decades, which leads to a break-down in widely-used number-theoretic cryptographic schemes. Vulnerable cryptosystems include RSA, ECDSA, and ECDH, which are currently utilized everyday to secure cyberspace and digital communications. In this thesis, we focus on lattice-based and provably-secure authentication. Firstly, we propose three lattice-based authenticated encryption (AE) schemes. To the best of our knowledge, these are the first...

Abstract
The Internet of Things (IoT) technology enables numerous things with different processing power and storage capacity to communicate and share data with each other. Considering the constrained devices of the IoT network in terms of processing and storage, designing a lightweight authentication scheme is quite important. So in this paper, we propose a lightweight authentication scheme based on Chebyshev Chaotic Maps. In the proposed scheme we apply a hierarchical structure to define different access controls for various entities. We then provide a formal analysis via the BAN logic to show the security of our scheme. Moreover, we compare our proposed scheme with previous ones in terms of...
