摘要:
近年来,传染性疾病比如肺炎的大规模爆发给人们敲响警钟。 关于传染病患者及其密切接触者的发现以及隔离对于控制疫情异常重要。 传统的密切接触者身份追踪依靠被感染者的记忆来回忆他 / 她接触过的人的名单,并向医院工作人员报告。 这种方法不准确、效率低,也不是一种快速抑制病毒传播的方法。 针对传染病密切接触者的身份追踪及其隐私保护问题,该文设计了一个传染病密切接触者身份追踪系统,可以保证患者及密切接触者的隐私不被泄露。 系统中的身份认证协议,利用零知识证明,证明相遇认证双方公钥的正确产生,节约了公钥证书验证的开销。 系统中改进了带属性的群签名,认证患者确诊的事实的同时,隐藏患者的身份,保护了患者及密切接触者的隐私。 系统能将患者的密切接触者信息及时锁定并秘密通知本人,来达到疫情控制的目的。 从安全性分析和性能分析来看,该系统具有较好的灵活性、安全性、计算效率。
Abstract:
In recent years,large-scale outbreaks of infectious diseases such as pneumonia have sounded alarm bells. The detection and isolation of? patients with infectious diseases and their close contacts is extremely important to control the outbreak. Traditional contactidentity tracing? ? ? ?relies on an infected person’s memory to recall a list of people he / she has been in contact with and report it to hospital staff. This method is inaccurate,inefficient,and not a quick way to suppress the spread of the virus. Aiming at the identity tracking and privacy protection of close contacts of infectious diseases,we design an identity tracking system for close contacts of infectious diseases,which can ensure that the privacy? of patients and close contacts is not leaked. The identity authentication protocol in the system uses zero-knowledge proof to prove the correct generation of the public keys of the two parties that meet and authenticate,saving the cost of public key certificate verification. The group signature with attributes has been improved in the system,which verifies the fact that the patient is diagnosed,and at the same time hides the patient’s identity and protects the privacy of the patient and close contacts. The system can lock the patient’s close contact information in a timely manner and secretly notify the patient to achieve the purpose of epidemic control. From the security analysis and performance an alysis,the system has better flexibility,security and computational efficiency.
