无线体域网中具有生物特征的基于身份的访问控制方案

Biometric identity-based access control for wireless body area networks

针对现有无线体域网(WBANs)中的安全和隐私性问题,为了充分利用生物特征的优势来确保WBANs内数据通信的安全性,首次提出了一种具有生物特征的基于身份的隐私保护技术,然后利用该技术在WBANs中提出了一种新的访问控制方法。在安全性方面,在随机预言机模型下是可证明安全的,并且具有机密性、认证性、完整性、不可否认性和匿名性;在性能方面,与现有方案相比,提出方案在计算开销和通信开销方面都具有优势。

Aiming at the problems of security and privacy in wireless body area networks(WBANs),in order to bring the advantages of biometric characteristics into full play to secure data communication within WBANs,this paper first proposed an identity-based privacy-preserving scheme based on biometrics,and then,presented a new access control approach for WBANs by the proposed design.From a security perspective,the proposed solution achieves confidentiality,authentication,integrity,non-repudiation and anonymity in the random oracle model.Performance analysis shows that the proposed scheme is the most efficient compared with other existing schemes in terms of computational cost and energy consumption.
