Abstract: An algorithm based on Arnold and RSA for optimal selection of large prime numbers in image encryption is proposed,including the Arnold transform and the RSA encryption algorithm.On the basis of the traditional RSA algorithm,this method proposed a scheme of the random selection of large prime numbers using the passage of time as the seed.Experimental results show that this method has high security,the decrypted image has a certain degree of robustness to additive noise attack.
