针对在现有的可再生能源绿色证书(简称"绿证")交易模式下,因用户个人隐私没有很好地融入设计中,导致在竞价交易过程中存在投标消息可能被窃听、篡改、泄露等隐私问题,提出了一种能保护用户隐私且可监管的可再生能源绿色证书交易方案.首先,设计了一种基于SM9(商密第九号算法)的环签密算法.算法的完成仅需 4 次双线配对操作,计算开销较低;其次,将用户自身唯一的身份标识与监管机构共同生成用户参与交易的匿名身份,同时兼顾监管机构对违法用户的追溯,以实现隐私和监管的平衡.最后,理论证明了本方案的安全性,实验证明了本方案具有较低的计算成本.
A Renewable Energy Certificate Trading Scheme with User Privacy Protection and Supervision
Under the current renewable energy certificate(referred to as"REC")trading model,the inadequate integration of personal privacy into the design has led to issues such as bid information being susceptible to eavesdropping,tampering,and leakage and other privacy issues during the bidding process,a renewable energy certificate trading scheme with user privacy protection and supervision has been proposed.Firstly,a ring signcryption algorithm based on SM9(Commericial secret NO.9 algorithm)is designed.The algorithm requires only four bi-linear pairing operations,resulting in low computational overhead.Secondly,the user's unique identity is combined with the regulatory authority to jointly generate an anonymous identity for users to participate in the transactions while taking into account the traceability of the offending user by the regulator in order to achieve a balance between privacy and regulation.Finally,the theory proves the safety of this scheme,and the experiments demonstrate its low computational cost.
