Secure Data transfer using tiny algorithm


Encryption of data plays a vital role in the real time environment to keep the data out of reach of unauthorized people, such that it is not altered and tampered and sending the in video format is most secured way to transfer the data through the network. The Video Stegnography is software, which tries to alter the originality of the file into some encrypted form and embed the file into an video file. The major task of the Video Stegnography is to provide the user the flexibility of passing the information implementing the encryption standards as per the specification and algorithms proposed and store the information in a form that is unreadable. The Application should have a reversal process as of which should be in a position to de embed the data file from video file and decrypt the data to its original format upon the proper request by the user.

The Entire application should strive to achieve a user friendly Graphical User Interface, which need to be in a self-learning mode for the end user. The System Should provide all the functional standards of proper navigation with in the environment, which makes it possible for the users to have a smooth flow while working under the environment. The Overall system should provide proper menu based navigation for easier navigation and operation. The Application should be designed in such a way that, as soon as it starts create a Buffer and associate this buffer to some homogeneous data environment, the application should ask the user for the Encryption Key details and should start its functionality upon the logistics that are provided with in this key. The key should be designed in such a way that it prevents the unauthorized persons from stealing the information at any point of time. This is some part of securing the data from third party people. And the other way of securing the data is using Steganography in which embedding the encrypted file in to a video file. If any one track that file they only see the video file not the data.

The application of De-embedding, Decryption should be a reverse process at the other end and should be translated only when the receiver of the data applies the proper reversal key. The Decryption process should have a log-based methodology that will take care of any errors that may be encountered while the system is under utilization and should record all those events, which are above the general standards of security.

This system basically uses the Tiny Encryption Algorithm to encrypt the passwords. This algorithm is a 64-bit block cipher with a variable length key. This algorithm has been used because it requires less memory. It uses only simple operations, therefore it is easy to implement.
