“…The traditional methods of key management like master/session key scheduling approaches [2], [3] are sophisticated and costly. Here, we propose a simpler technique that derives the required secrecy for frame keys from secret bits delivered by Wyner secrecy encoder over the created wiretap channel.…”

“…T RADITIONALLY, end-to-end secrecy delivery relies on symmetric or asymmetric encryption residing in the upper layer of a communication system, as well as sophisticated key management schemes [2], [3]. Without requiring a secure cipher, Wyner-type secrecy encoding provides a completely different solution to link-wise secret message delivery by random binning tailored to some presumed wiretap channel models in physical layer [4], [5].…”

This paper considers the problem of end-to-end security enhancement by resorting to deliberate noise injected in ciphertexts. The main goal is to generate a degraded wiretap channel in the application layer over which Wyner-type secrecy encoding is invoked to deliver additional secure information. More specifically, we study secrecy enhancement of the Data Encryption Standard (DES) block cipher working in cipher feedback model (CFB) when adjustable noise is introduced into the encrypted data in an application layer. A verification strategy in the exhaustive search step of the linear attack is designed to allow Eve to mount a successful attack in the noisy environment. Thus, a controllable wiretap channel is created over multiple frames by taking advantage of errors in Eve's cryptanalysis, whose secrecy capacity is found for the case of known channel states at receivers. As a result, additional secure information can be delivered by performing Wyner type secrecy encoding over superframes ahead of encryption. These secrecy bits could be taken as symmetric keys for upcoming frames. Numerical results indicate that a sufficiently large secrecy rate can be achieved by selective noise addition.

Is the newly born quantum cryptography the ultimate solution for information security? A technique needs to be theoretically strong and also practically viable. But quantum cryptography comes to naught in the latter. We present here some of the quantum's theoretical weaknesses like lack of digital signatures (or any algorithm) along with its many real time implementation problems. We further pursue with the discussion about the potency of classical cryptography and its resplendent capabilities in providing security.
