A heuristic approach for secured transmission of image based on Bernstein polynomial

Public key cryptosystem or the asymmetric crypto system is more secured than secret key method because a pair of related keys is being used at both sender and receiver's end. In this paper we propose an efficient Bernstein polynomial over Galois field GF(p). This public key cryptographic technique is used for secured transmission of image. This work considers compressing the original image using Bernstein image. The compressed image is encrypted at the sender's end and decrypted by the receiver using the proposed cryptographic algorithm. The decrypted image is decompressed to recover the parent image.
