Image Encryption Decryption Using Chaotic Logistic Mapping and DNA Encoding
This addresses security for image data transmission, but it is incremental as it builds on existing chaotic encryption methods.
The paper tackled image encryption by combining chaotic logistic mapping with DNA encoding and a 32-bit ASCII key, resulting in better performance than using chaotic logistic mapping alone, as measured by metrics like Peak Signal to Noise Ratio and Structure Similarity.
In this paper we have proposed a method that uses chaotic logistic mapping and DNA encoding to encrypt the image. A 32 bit ASCII private key is used to diffuse the image. The results demonstrated clearly show that encryption algorithm based on chaotic logistic mapping and DNA encoding gives better result than encrypting only with chaotic logistic mapping. The proposed method also takes into account the possible parametric like Peak Signal to Noise Ratio and Structure Similarity.
