Advanced functionalities and post-quantum security through the lens of lattice-based cryptography

Willy Quach

Over the last twenty years, lattice-based cryptography has quickly become a central component of modern cryptography. Its most prominent characteristics are (1) its capacity to build cryptographic primitives with powerful functionalities, famously including fully-homomorphic encryption, and (2) its widely-believed resilience against quantum attacks, leading to the currently most prevalent family of candidates for post-quantum cryptography. In this thesis, we further study these two fundamental features of lattice-based cryptography. First, we introduce a new advanced cryptographic primitive, that we call laconic function evaluation, which captures general sender-optimized two-party computation. We build laconic function evaluation from lattice-based assumptions, and show applications to efficient secure multi-party computation. Second, we take a systematic approach to studying post-quantum security of cryptographic protocols. We show that, perhaps surprisingly, post-quantum resilience of a computational assumption does not automatically imply post-quantum security of cryptographic primitives built upon it, including encryption and signature schemes. We do so by exhibiting counter-examples based on lattices. Last, we show that natural interactive protocols from lattices shed light on cryptographic arguments systems, and more specifically the so-called Fiat-Shamir transform. As a byproduct, we uncover a conceptual connection between two families of practical lattice-based signatures.--Author's abstract

Benchmarking Speed of Post-Quantum Lattice Based PKE/KEM Schemes Using Liboqs

Recent advances in quantum computing have high-lighted the vulnerabilities in contemporary RSA encryption. Shor's approach for factoring numbers is becoming more tractable as quantum computing advances. This jeopardizes the security of any cryptographic system that is based on the complexity of factorisation. Many other crypto-systems based on theories like Elliptic Curve Cryptography are also vulnerable. To keep a cryptographic system safe against a quantum adversary, we must develop approaches based on a hard mathematical problem that is not vulnerable to quantum computer attacks, and we must develop Post Quantum Cryptography (PQC). One potential option is the use of lattices in a system called ring Learning with Errors (rLWE). Several techniques for postquantum encryption have been submitted to NIST. This paper studies the different speeds of different lattice-based protocols.

A Practical Implementation of Post-Quantum Cryptography for Secure Wireless Communication

Babatunde Ojetunde, Takuya Kurihara, Kazuto Yano +2 more

Recent advances in quantum computing have prompted urgent consideration for the migration of classical cryptographic systems to post-quantum alternatives. However, it is impossible to fully understand the impact that migrating to current Post-Quantum Cryptography (PQC) algorithms will have on various applications without actual implementation of quantum-resistant cryptography. On the other hand, PQC algorithms come with complexity and long processing times, which may impact the Quality of Service (QoS) of many applications. Therefore, PQC-based protocols with practical implementation across various applications are essential. This paper introduces a new framework for PQC standalone and PQC-AES (Advanced Encryption Standard) hybrid Public Key Encryption (PKE) protocols. Building on prior results, we focus on securing applications such as file transfer, video streaming, and chat-based communication using enhanced PQC-based protocols. The extended PQC-based protocols use a sequence number-based mechanism to effectively counter replay and man-in-the-middle attacks and mitigate standard cybersecurity attack vectors. Experimental evaluations examined encryption/decryption speeds, throughput, and processing overhead for these standalone PQC and PQC-AES hybrid schemes, benchmarking them against traditional AES-256 in an existing client-server environment. The results demonstrate that the new approaches achieve a significant balance between security and system performance compared to conventional deployments. Furthermore, the comprehensive security analysis confirms the robustness and effectiveness of the proposed PQC-based protocols across diverse attack scenarios. Notably, the PQC-AES hybrid protocol demonstrates greater efficiency for applications handling larger data volumes (e.g., 10–100 KB) with reduced latency, underscoring the practical necessity of carefully balancing security and operational efficiency in the post-quantum migration process.
