Due to the increased demand of intelligent edge applications, efficient computational offloading schemes and secure communication between edge and cloud server has become essential. This chapter presents an intelligent framework that integrates Blockchain technology and Generative AI to achieve intelligent computation offloading in an edge computing. The framework includes generative models to encode the sensitive data and blockchain based smart contract infrastructure. To ensure confidentiality, the generative adversarial network is used to encode the data into images or audio files. The smart contract is applied to log task metadata and verify the data integrity. The immutable execution logs are ensured by blockchain based infrastructure. The framework allows seamless computational offloading between edge and cloud server with end-to-end security. The experimental results depict the system overhead with respect to interception, latency and tampering. The fusion of AI-driven data masking provides a secure and intelligent computation offloading mechanism in the decentralized manner.
