Abstract：With the popularization of electronic medical systems, electronic medical records have become important tools for hospitals to record and share patients\' medical information. Electronic medical records are not only of great value for clinical care and patient follow-up, but also serve as key evidence for medical insurance claims. However, problems such as medical record forgery and medical insurance fraud occur frequently, seriously affecting the credibility of the medical system. Although technologies such as cloud computing, big data, and artificial intelligence are widely used in the privacy protection of electronic medical records, most of the existing schemes focus on the data sharing process and pay insufficient attention to the security issues in the medical record generation process. To address this, this paper proposes a quantum-resistant electronic medical record generation scheme based on aggregate signature technology. DuriA Lattice Based Quantum-Resistant EMR Generation and Access Control Schemeng the medical treatment process, doctors and patients confirm the medical record content through dual signatures to ensure patients\' informed consent and approval of the treatment plan, preventing medical record tampering and subsequent disputes. In addition, in view of the potential threat of quantum computing to traditional cryptography, this paper designs a quantum-resistant access control scheme for electronic medical records by combining lattice cryptography technology, further strengthening the privacy protection ability of electronic medical records.
