一种用于移动云计算的轻量级匿名验证和密钥协商方案
首发时间:2019-04-08
摘要:移动设备通过来自不同位置的不可信的无线网络与云服务器共享数据,这给移动云计算带来很多的安全风险。因此,安全性是移动云计算首要解决的关键问题。此外,由于移动设备的资源有限,无法执行过于复杂的计算。因此,本文提出了一种轻量级的匿名认证和密钥协商方案,以在移动设备和云服务器之间建立经过身份验证的通信会话。提出的方案仅使用散列函数,连接操作和按位异或运算。本文还采用自动安全验证工具ProVerif来验证所提方案的安全属性并进行非正式的安全性分析,然后将该方案的安全性和计算开销与其他相关方案进行比较,从而证明所提出的方案在这些方面具有更好的性能。

A lightweight anonymous authentication and key agreement scheme for mobile cloud computing
Abstract:Mobile devices share data with cloud servers through untrusted wireless networks from different locations, which leads to more security risks for mobile cloud computing. As such, security is the primary problem to be solved in mobile cloud computing. In addition, because the limited resources of mobile devices, they cannot perform too complicated calculations. Therefore, this paper put forward a lightweight anonymous authentication and key agreement scheme to establish authenticated communication sessions between mobile devices and cloud servers. The proposed scheme uses only hash functions, concatenate operations and XOR operations. This paper also uses the automatic security verification tool ProVerif to verify security properties and conduct informal security analysis, and compares the security and computer overhead with other related schemes to confirm that the proposed scheme has better performance in these aspects.
