摘要
为更安全、高效地共享智能电网中的数据,提出基于属性加密的安全数据共享(AEDS:Attribute-Based Encryption Secure Data Sharing)算法。AEDS算法采用属性加密策略实现安全数据共享,并通过模糊访问策略,提高接入数据的安全性。引用线性密钥共享策略,支持任意单调的访问结构,进而增强访问策略的可表述性。性能分析表明,提出的AEDS算法有效地提高了接入效率,增强了接入数据的安全性。
To share data in a smart grid safely and efficiently,AEDS(Attribute-Based Encryption Secure Data Sharing)algorithm is proposed.In AEDS,we propose a practical attribute-based encryption scheme for securing data sharing and data access in smart grid architectures with the added advantage of obfuscating the access policy.This is aimed at preserving data privacy in the context of competing smart grid operators.We build our algorithm on linear secret sharing scheme for supporting any monotone access structures and thus enhancing the expressiveness of access policies.The performance analysis shows that the proposed AEDS algorithm effectively improves the access efficiency and enhances the security of access data.
