This invention discloses a quantum-resistant method and system based on stateless signatures and execution isomorphism, belonging to the field of quantum-resistant cryptography. First, the sender generates an mKEM broadcast payload based on a modulus error rounding algorithm and signs it using a stateless hash signature algorithm. The receiver performs microsecond-level verification of the signature at the network card driver layer; if verification fails, the signature is silently discarded. After successful verification, a dedicated PQC hardware engine decapsulates the signature, implicitly outputting a pseudo-random scrap key if verification fails. The operating system executes an I / O-aware microarchitecture with isomorphic execution, forcing subsequent processes to maintain physical isomorphism in system calls, memory accesses, and peripheral bus activities, regardless of whether the key is real or scrap. This invention eliminates the risk of private key leakage caused by cloud-based state management through stateless signatures and completely eliminates distinguishable side-channel fingerprints across the entire link through physical-level execution isomorphism, achieving system-level quantum-resistant security in high-concurrency scenarios.
