Abstract:

Protection to the data over the open network is very important. Encryption is one of the ways out to make your data safe and secure. In this paper, the main objective is to present a modified image encryption technique, which does not only makes the image very difficult to retrieve by any other person except the recipient but also reduces the time for encryption. This proposed encryption technique is the combined technique of various methods of encryption such as: RSA algorithm, Bit Rotation method, Ex-Hill Cipher method, Bit Reversal method and Randomization using Permutation. First the pixels value of an image is converted into eight bit binary format. RSA algorithm is chosen to generate the passwords, encrypting key and decrypting key. After this above mentioned methods are applied to encrypt the image. After the generation of new 8 bit value, the binary values are converted back to decimal format and the new pixels values replace the older one.

Keywords:

RSA, Ex- Hill Cipher, Permutation, Bit Rotation and Reversal.
