What The Most Secure Email In The Universe Would Look Like

 

 

Researchers develop covert optical communication system

 

 

 

” Say you wanted to send an email more secure than any message that had ever been transmitted in human history, a message with absolutely no chance of being intercepted. How would you do it?

  You may have encrypted your message according to the highest standards, but encryption doesn’t guarantee secrecy. The fact that you sent it is still detectable. An intercepting party in possession of just a few clues such as your identity, the receiver’s identify, the time of the message, surrounding incidents and the like can infer a great deal about the content of the message in the same way that the NSA can use your metadata to make inferences about your personality. You need to conceal not just what’s in the message but its very existence.

  The answer? Make your message literally impossible to detect. A team of researchers from the University of Massachusetts at Amherst and Raytheon BBN Technologies led by Boulat A. Bash have created a method for doing just that, cloaking electronic communications so that the communication can’t be seen. They explain it in a paper titled Covert Optical Communication.

  The question of exactly how secure any communication can be is of no small relevance either to national security watchers worried about losing secrets or to a public increasingly concerned about governmental invasion of digital privacy. The breakthrough shows that it is possible to send a message that can’t be intercepted, no matter how determined the National Security Agency is to intercept it. “
