Is it possible to detect Stealthy False Data Injection attack through chaotic cryptography? [migrated]

I am doing a research on detecting Stealthy False Data Injection (SFDI) attacks in a smart grid context (a related paper). Besides I am working on a chaotic cryptography (e.g. with Lorenz attraction) for encryption and decryption of the tr… Continue reading Is it possible to detect Stealthy False Data Injection attack through chaotic cryptography?
