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.

Bluetooth is undoubtedly one of today's most fancied ways of wireless communication. It operates in the ISM band and thus is freely available for general and industrial use. Being such a widely used way of communication it should be really promising when is comes to security and power consumption. However today's Bluetooth has not evolved to full its potentials in these areas and this paper is all about taking Bluetooth to its next level. This will promise greater security along with much efficient power consumption. The paper discussed about the present scenario of Bluetooth and about the possible improvements it can receive like adaptive range and encrypted hopping.
