Hybrid Security Approach for Multilevel Security in Data Communication

Information Science and Engineering

NATIONAL CONFERENCE on VLSI, COMMUNICATION AND SIGNAL PROCESSING (NCVCS-2017)

In the age of multiple, growing connections and online transfers of data across networks, it has become increasingly necessary to secure sensitive data. To ensure that the access to information is private and only by authorized persons, it must be secured over the transmissions. A Hybrid Security Approach for multi-level data security will be beneficial in solving the existing problems of keeping data safe and secure over its transfers across networks - involving countless computer systems and users, a basic achievement of which is the deliverable of this project. By combining the functionalities of encryption from Cryptography and concealing of the information from Steganography, powerful security can be established for the data. A strong Cryptographic algorithm - AES (Advanced Encryption Standard) and an appropriate Stenographic method – LSB (Least Significant Bit) are identified and they are implemented to work together to raise the potent of the information security setup. The confidential information required to be secure is encrypted by the AES algorithm, and this encrypted data is concealed in an image by the Least Significant Bit algorithm of Steganography. This project proposes multi-level data security, which can be integrated into networks and online transactions in the world of Net Banking for tighter security and safer transactions and transmissions of sensitive data. It can also prove to be helpful in advancing crypto-economics and cryptocurrencies through other forms of Information Hiding as well.
