An Efficient Hybrid Encryption Scheme for Encrypting Smart Grid Business Data

The continuous development of smart grid based on 5G power communication network requires the adoption of data encryption to secure the power business data. In this paper, we propose an efficient symmetric cryptographic algorithm based on garbled coding, and combine it with ECC asymmetric cryptographic algorithm and SHA-256 hash algorithm to propose an efficient hybrid encryption scheme suitable for encrypting electric power business data. This paper also analyzes that the proposed hybrid cryptographic algorithm has sufficiently high security, and the simulation verifies that the proposed method has high encryption and decryption efficiency with appropriate data chunking ratio.
