Who would have thought of marrying knowledge from more than 60 years ago with modern communications – through the clever implementation of an unbreakable cipher from World War 2 into emails. The Vernam cipher was developed all the way back in 1917 by AT&T engineer Gilbert Vernam alongside U.S. Army Captain Joseph Mauborgne, where this cipher was used to protect relayed data in the second World War. Captain Mauborgne further strengthened the cipher through the implementation of genuinely random keys which will not repeat, and Singaporean company Rune Information Security Corp. decided to be inspired by his work by delivering an e-mail encryption system that they call Deadbolt.

The Deadbolt system comprises of a USB stick which will plug into your Mac or PC, where all that is required after that would be a few clicks in order to secure data, and it can be used with either the common OpenPGP encryption or the Vernam cipher. Email is not the only thing it secures, as your Facebook, Skype, Gmail and LinkedIn messages will also fall under a similar umbrella of protection.
