匿名验证隐藏证书及其应用

Anonymously verifiable hidden credentials and their applications

在结合Holt等人的隐藏证书、IBE算法以及秘密共享这些方案的基础上,设计了一种新的匿名验证隐藏证书方案,在认证过程中可以保护用户的身份信息以及证书中的敏感信息,并且最后给出了一个医学方面的应用场景。分析证明:本方案能够避免攻击者通过收集用户的网络行为信息、利用数据分析等手段获取用户的敏感信息,因此该方案是安全有效的,能够更好地保护用户的隐私。

Basing on hidden credentials scheme designed by Holt et al,IBE scheme,and secret sharing scheme,this paper constructed a new anonymously verifiable hidden credentials scheme,which could protect the user＇ s identity information and sensitive information in the process of verification.Finally,it gave a medical application scenario.Analysis shows this scheme can resist an attacker who gets the user＇ s sensitive information by collecting the user＇ s network behavior information,utilizing data analysis,etc.So,this scheme is secure and effective,and can better protect the privacy of users.
