Abstract

Abstract: In order to reduce storage space and computational cost of the digital certificate security system in smart grids and increase the coupling degree of encryption and signature, the mapping method of smart grid and certificateless signcryption scheme of role is put forward, and the application environment of certificateless signcryption on smart grids is constructed, which is based on the analyses of security of data transmission in smart grid. By using the elliptic curve cryptography, a digital signcryption scheme for smart grids is developed. In order to improve the communication security, the trusted third party is introduced into communication of the smart grid. Combined with the intelligent nodes, a key pair is produced. By taking encryption process into the signing process, this method improves the transmission efficiency of communication. Compared with the security of the existing algorithms, the proposed scheme has the advantages on confidentiality, integrity, nonrepudiation and antiforgery. The application test results show that the scheme can meet the requirements of real-time data transmission in smart grids.
