Towards A Novel Cross-Media Encryption-Cum-Obfuscation Technique

The safeguarding of sensitive information has always been the mission of researchers and cryptographers since time immemorial. People all around the world have always felt the dire need to establish and ensure information security, i.e., to ascertain that crucial and confidential information is kept secure from any unwanted access and/or attack. Moreover, it is also necessary to provide access to confidential data to legitimate and authentic users after confirming login credentials. Cryptography is a well-known technique for maintaining confidentiality, integrity, authentication, and non-repudiation of messages, whereby the sender encrypts the plain text to generate ciphertext, sends it across a communication medium which on the receipt is decrypted by the authentic receiver. This paper proposes a novel cross-media encryption-cum-obfuscation technique where the encryption technique will obfuscate itself by changing its media. To simulate the proposed obfuscation technique in the realworld, a specific hardware setup is requisite at both the terminals. So, the transmitter and receiver hardware circuitry is smartly designed to dynamically change the signatures and achieve enhanced security. Thus, it can be said that the proposed technique is robust against the traditional cryptanalysis methods and can ensure information security by obfuscating the data.
