Communication is the process of transmitting information from source to destination. The information exchanged between sender and receiver through the proper channel. The information should not be stolen by unauthorized parties like hackers while sending or receiving via channel. To avoid this stealing of the information cryptography techniques are used. The key is playing prominent role in cryptography. This paper proposes a novel method for key generation by using nearest primes. Further 2's complement and logical operations are used in encryption and decryption process. The final cipher text is generated by representing the intermediate cipher in matrix form and then read by column wise.Keywords

Steganography is the principles and techniques of embedding data within other data. Cryptography is the principles and techniques of changing the data one form to another form. Image Steganography is the process of hiding data within an image. Steganography along with encryption techniques provides an additional security to the data. Several techniques exist for image steganography, in this work, a new lossless image steganography technique along with cryptographic method is presented. Lossless compression is a class of algorithms that allows the original data to be perfectly reconstructed from the compressed data. Present work concentrates the lower nibble of pixels in the cover image for embedding the information; further encryption techniques will be applied. It is not possible for the hacker to retrieve the secured data from the cover image.Keywords
