摘要:

摘 要:研究了基于位置密码学中安全定位协议的可证明安全问题。在通用可组合安全框架下,提出了安全定位的可证安全模型。根据安全定位协议的需求,设计了安全定位的理想函数。同时,作为基于位置密码学的一种前提假设,设计了BRM模型的理想函数。此外,以1-维空间的安全定位协议为例,证明了该协议在BRM模型下能够实现安全定位的理想函数。

Abstract:

The provable security of secure positioning in position-based cryptography was investigated,and the provable secure model of secure positioning was established in the universally composable framework.According to the security requirements of secure positioning,the ideal functionality of secure positioning firstly was proposed.Then,the ideal functionality of bounded retrieval model was designed one of the set-up assumptions in position-based cryptography.Lastly,the secure positioning protocol in 1-dimension space,as an example,could securely realize the functionality of secure positioning in the bounded retrieval model.

Key words: position-based cryptography, secure positioning, UC secure
