摘要
数据可恢复性证明方案可以有效解决用户将数据存储在不诚实的服务器上时,需要对数据的完整性进行验证的问题。针对目前存在的大部分方案都是使用的基于身份的密码体制的问题,采用更直观灵活的基于属性的密码体制设计了基于属性的数据可恢复性证明方案。给出了方案的相关定义、安全模型和具体的构造,同时证明了方案的正确性和安全性。
When the user stores the data on a dishonest server,the integrity of the data needs to be verified,so the proof-of-retrievability(POR)system is proposed.Aiming at the problem of identity-based cryptosystem used in most of the existing solutions,a more intuitive and flexible attribute-based cryptosystem is adopted to design an attribute-based data recoverability proof scheme.This paper firstly proposed definition and model of an attribute-based proof of retrievability with public verifiability,then,constructed an attribute-based proof of retrievability with public verifiability,finally,it proves its correctness and security.
