ABSTRACT

The main objective of this project is to make a secure image data transmission over the network and protecting the data from the intruders.

To encrypt and decrypt the images using the keys generated by the RSA algorithm. It enhances the security of the multimedia data transmission over large networks.

SUB SYSTEM AND THEIR MODULES

METHODS

ENCRYPTION: This module encrypts the plain image which

was selected by the sender. The image is encrypted by merging the public

key value which was provided by the receiver and then the image will be send to the receiver.

METHODS

DECRYPTION: The encrypted image is merged with the

private key value to get decrypted image. Private key value is generated by seconds

value in date function , so it differs for each and every key generation event.

METHODS

KEY GENERATION: The receiver generates both public and

private keys. Public key is visible to both sender and

receiver. Private key is known only to receiver , which

is generated by RSA algorithm.

KEY GENERATION PROCEDURE (RSA)

Select p, q p, q values are system’s second’s value Calculate n = p x q Calculate (n) = (p-1) (q-1) Get integer e public key value entered by the receiver Calculate d d = e-1 mod (n) Public key KU = {e, n}  Private key KR = {d, n}

JAVA SWING

Swing uses ABSTRACT WINDOW TOOLKIT features to get access to GUI system.

Swing components are light weight. They are not platform native widgets.

ADVANTAGES

SECURE: Private Key is only known to Receiver.

DYNAMIC KEY GENERATION: Private Key generated by Systems Second’s Values.

SHUFFLING MATRIX: Original Image is Splitted and Shifted using the Shuffling Matrix.
