In the data encryption standard,AES is a relatively advanced commercial encryption standard.In the AES algorithm,the finite field theory is the core of the algorithm,which has the characteristic of high security.Only using finite field operations can make the encryption speed significantly reduced.Based on this,it proposes an image encryption algorithm based on chaos theory and finite domain,which is combined with the chaotic mapping and binary finite field.Chaos theory has rapidity and security,as well as the finite field,so the image encryption has the character of security.Through the experimental analysis,the algorithm has good encryption effect,anti-attacking,anti-noise attack,and encryption speed,high degree of safety features.
