High-Performing Quantum-Safe Password-Authenticated Key Exchange for Mobile Devices

Peixin Ren, Xiaozhuo Gu, Kaibo Liu

The Password-Authenticated Key Exchange (PAKE) protocol is a useful tool for establishing secure remote communication between users, especially given the prevalence of amplifying a human-memorable password into a strong session key in the age of hand-held devices. Recent advances in quantum computing have stimulated interest in quantum-safe cryptographic schemes. Therefore, we propose QSPAK and QSPPK, two post-quantum and efficient PAKE protocols which are parallel extensions of PAK and PPK, but based on the hardness assumption over module lattices. Specifically, we make a comprehensive trade-off among multiple significant performance indicators such as the post-quantum security, the failure rate, the communication cost and the running time to guide optimal parameter choices. This rigorous instantiation has never been seen in previous PAKE papers. Additionally, utilizing the flexibility of module lattices, we provide three parameter sets (#1, #2, and #3) matching different security scenarios. We implement and benchmark QSPAK and QSPPK against other competitive proposals. The performance results indicate that our QSPAK and QSPPK, besides being more efficient, exhibit the flexibility and security advantages over the latter schemes. Furthermore, we construct a post-quantum password-authenticated TLS 1.3 framework, aimed towards provide a further suggestion for IETF standardization of quantum-safe PAKE.

QT-PAKE: Secure Messaging via Quantum-Safe Threshold PAKE

Password authentication is a prevalent method of user verification across the Internet, and its use extends to scenarios where resources are limited. However, current password authentication protocols primarily rely on traditional password authenticated key exchange (PAKE) protocols (e.g., SRP, OPAQUE), which are vulnerable to attacks by quantum adversaries. To date, no efficient quantum algorithm has been found to solve the common challenges in lattice-based cryptography. Therefore, quantum-resistant PAKE protocols are generally built upon lattice-based cryptography. In this work, we propose a threshold verifiable oblivious pseudorandom function () protocol based on secret sharing. We then integrate it into a PAKE protocol and present an instantiation of a quantum-safe threshold PAKE protocol () based on the Ring Learning with Errors (RLWE) assumption. This integration gives our PAKE protocol resistance to precomputation attacks, similar to OPAQUE. Furthermore, by incorporating thresholding techniques into the PAKE protocol, we mitigate the risk of single points of failure on the server side. Our protocol not only preserves the security guarantees of traditional PAKE schemes but also resists attacks from quantum adversaries. We also provide a comprehensive security analysis and evaluation of, providing valuable insights for its practical implementation.
