Multimedia Wireless Sensor Network Platform Data Encryption Algorithm based on Blockchain Technology

This research presents a data encryption technique based on blockchain technology to address issues of inadequate encryption efficacy and information loss in multimedia platforms' data encryption algorithms. The study explores the DES encryption method, its symmetrical key algorithm and public key algorithm, electronic envelopes, and message authentication. It also investigates asymmetric encryption techniques using neural networks with chaotic attractors and sequences. The goal is to improve the efficiency of data encryption and ensure data correctness, requiring a blockchain-based data encryption system. The empirical evaluation shows that the proposed method can successfully encrypt multimedia data, providing excellent encryption results and ensuring data integrity. The findings provide a theoretical foundation for further research in this area.
