Title:
SoK: PQC PAKEs - Cryptographic Primitives, Design and Security
Authors: Nouri Alnahawi, David Haas, Erik Mauß, Alexander Wiesmaier
Abstract:PAKE protocols are used to establish secure communication channels using a relatively short, often human memorable, password for authentication. The currently standardized PAKEs however rely on classical asymmetric (public key) cryptography. Thus, these classical PAKEs may no longer maintain their security, should the expected quantum threat become a reality. Unlike prominent security protocols such as TLS, IKEv2 and VPN, quantum-safe PAKEs did not receive much attention from the ongoing PQC integration efforts. Thus, there is a significant gap in awareness compared to PQC schemes that are subject to the official governmental and institutional standardization processes. In the work at hand, we provide a comprehensive overview of the existing PQC PAKEs focusing on their design rationales, authentication methods and used asymmetric key agreement primitives. We highlight their performance and properties as per their assumed security assurances and practical usage in applications. Moreover, we address PAKE designs that are still non-present in the PQC realm and discuss the possibility of their adaptation. Thus, we offer a detailed reference and derive future work for quantum-safe PAKEs.
