随着信息技术的快速发展，数据安全和用户的隐私越发受到重视。本文提出了一种匿名认证密钥交换(Anonymous Key Exchange, AKE)协议，旨在为医疗场景下的医疗数据共享和患者身份隐私提供安全和隐私的保护。该方案通过使用累加器、零知识证明和关联数据加密等技术，实现用户匿名的认证和安全的会话密钥协商，有效防止敌手对于用户和医用物联网设备的攻击，还能抵御诚实且好奇的医疗机构对患者身份的猜测。相较于现有的方案提供了更强的隐私安全保护，并且很好地平衡了性能和安全性，具有重要的理论价值和意义。With the rapid development of information technology, data security and user privacy have been paid more and more attention. This paper proposes an Anonymous authenticated Key Exchange (AKE) protocol to provide security and privacy protection for medical data sharing and patient identity privacy in medical scenarios. By using accumulator, zero-knowledge proof and associated data encryption technology, the scheme realizes anonymous user authentication and secure session key agreement, which effectively prevents adversaries from attacking users and medical IoT devices, and can resist honest and curious medical institutions from guessing the patient’s identity. Compared with the existing schemes, it provides stronger privacy security protection, and a good balance between performance and security, which has important theoretical value and significance.
