Loc-Auth:通过基于属性的加密实现位置认证

Loc-Auth: Location-Enabled Authentication Through Attribute-Based Encryption

Marcos Portnoi, Chien-Chung Shen

摘要:

传统的用户认证涉及将用户名和密码输入到系统中。强身份验证安全性要求,除其他要求外,长,经常难以记住的密码。双因素身份验证有助于提高安全性,尽管作为副作用,可能会恶化用户体验。我们描绘了一个移动登录方案,受益于用户的属性,用户希望利用的服务,和位置(用户在哪里,什么服务是可用的)作为认证因素之间的动态关系。我们展示了我们的计划采用蓝牙低功耗信标的位置感知和基于属性的加密的表现力,以捕捉和利用所描述的关系。低功耗蓝牙信标广播具有编码访问策略的加密消息。在信标的范围内,具有适当属性的用户能够解密广播消息并获得允许用户执行简短或简化登录的参数。

英文摘要:

Traditional user authentication involves entering a username and password into a system. Strong authentication security demands, among other requirements, long, frequently hard-to-remember passwords. Two-factor authentication aids in the security, even though, as a side effect, might worsen user experience. We depict a mobile sign-on scheme that benefits from the dynamic relationship between a user's attributes, the service the user wishes to utilize, and location (where the user is, and what services are available there) as an authentication factor. We demonstrate our scheme employing Bluetooth Low Energy beacons for location awareness and the expressiveness of Attribute-Based Encryption to capture and leverage the described relationship. Bluetooth Low Energy beacons broadcast encrypted messages with encoded access policies. Within range of the beacons, a user with appropriate attributes is able to decrypt the broadcast message and obtain parameters that allow the user to perform a short or simplified login.
