智能电网作为一种技术创新,在物质性、经济性、效率性和可靠性方面提高了电力服务。这归功于双向通信特性,不仅使细粒度的能源使用数据可供不同实体使用,而且还促进了自动化电网管理。然而,与其他方分享该等能源使用数据可能会导致客户敏感资料泄漏。此外,数据很容易被任何内部或外部攻击者篡改,从而破坏数据的价值。因此,在与其他方共享能源使用数据的同时,保护客户的隐私并提供真实性和可验证性至关重要。本文提出了一种基于双线性映射累加器的可编辑签名方案(RSS-BMA),该方案在保证共享数据的可验证性的同时,还能保护用户的隐私。此外,我们设计的批数据块验证属性通过禁止对一批数据块进行额外的编辑,不仅提高了效率,而且提高了安全性。我们对所提出的方案的效率和安全性进行了广泛的分析,结果表明,我们的构造比其他方案更实用。
As a technological innovation, smart grid improves electricity services in terms of substantiality, economics, efficiency, and reliability. This owes to the bi-directional communication property which not only enables the fine-grained energy usage data to be available for different entities but also facilitates the automated grid management. However, sharing such energy usage data with other parties could potentially cause the leakage of customers’ sensitive information. In addition, the data are vulnerable to be tampered with by any internal or external attacker such that the value of data could be destroyed. Therefore, it is crucial to preserve customers’ privacy and provide authenticity and verifiability while sharing energy usage data with other parties. In this paper, we propose a bilinear-map accumulator based redactable signature scheme (RSS-BMA) which allows customers to safeguard their privacy while guaranteeing the verifiability of shared data. Furthermore, thebatch-data-block verificationproperty of our design enhances not only efficiency but also security by prohibiting additional redaction to a batch of data blocks. We analyze the efficiency and security of our proposed scheme extensively, and the results indicate our construction is more practical than others.
