Research Interests

My current focus in on quantum and classical cryptography, physics based and also pure mathematics based. I am continue to develop my previous KCQ (keyed communication in quantum noise approach) approach, versions of which have been implemented in the US and Japan. I introduce a new technique DBM (decoy bits method) on which patent appliction has been filed, but the details of which are yet to be released.
