摘要
为了提高加密与签名的耦合度,减少数字证书存储空间和计算开销,结合无证书签密技术,设计一种基于智能电网的数字签密安全方案,简单阐述密码技术在智能电网中的应用,分析智能电网数据传输中的安全问题。将可信第三方与智能节点共同产生的密钥对引入智能电网通信,提高了通信的安全性,将加密过程融入签名过程中,提高了通信的传输效率。与现有密码算法在安全上相比,该方案具有消息的保密性、完整性、抗否认性和抗伪造性等特点。测试结果表明,该方案不仅能够满足智能电网数据传输中的安全性需求,还能够满足智能电网数据传输的实时性要求。
In order to increase the degree of coupling for encryption and signature, and reduce storage space and computational requirement of the digital certificate, a digital signcryption scheme to smart grid is designed, combining with certificateless signcryption technology. It simply illustrates the application of cryptography in the smart grid and analyzes the security problem in data transmission. Then introduce the key pair produced by both the trusted third party and intelligent nodes into the communication of smart grid. The method improves the security of communication. It also integrates the encryption process into the sign process to improve the transmission efficiency of communication. Compared with the existing algorithm to smart grid in the security, this scheme has features of confidentiality, integrality, nonrepudiation and anti-forgery. The application test results show that the scheme can not only meet the requirements of data transmission security, but also meet the real-time requirements of data transmission in smart grid.
