摘要

In the context of emerging quantum threats, traditional authentication mechanisms—particularly those based on one-time passwords (OTP)—are becoming inadequate. This paper introduces a post-quantum authentication model that combines an OTP scheme derived from an ML-DSA signature (from the PQClean project) with a Trusted Execution Environment (TEE). The TEE ensures the secure generation, storage, and usage of critical cryptographic elements, thereby strengthening resilience against both software and hardware attacks. This approach provides a robust response to modern security challenges. A security analysis and in-depth discussion position this model as a credible and scalable alternative for authentication in a post-quantum world.
