Research on smart grid data encryption algorithm based on new complex chaotic system

Smart grid systems necessitate robust data encryption to safeguard sensitive data. Hardware limitations and computational complexity, however, restrict the real-time applicability of encryption in certain smart grid environments. This investigation proposes a novel encryption algorithm, the Genetic Algorithm-Enhanced 8-Dimensional Chaotic System (GA-8D chaotic system), based on a complex chaotic system enhanced by a genetic algorithm, to secure smart grid data. The data was collected from a simulated smart grid environment, comprising real-time grid load data and sensor inputs. The proposed GA-8D chaotic system technique integrates a Genetic Algorithm (GA) and an 8D chaotic system for strong key generation and encryption. This approach enhances encryption speed and security by evolving optimal parameters using genetic algorithms, thereby ensuring higher performance in smart grid applications. The 8D chaotic system encryption technique is utilized to securely encrypt data and sensor images within the smart grid, guaranteeing data integrity and confidentiality within the smart grid architecture. The proposed algorithm demonstrated superior performance in encryption speed (0.1 ms), training accuracy (0.98), security strength (98%), and computational efficiency (450 bits). The results indicate that the algorithm is scalable for smart grid data encryption. The GA-Enhanced 8D chaotic system encryption algorithm successfully addresses the security challenges in smart grid data transmission.
