Scientists are probing the eerie world of quantum physics in a quest to develop the elusive wonder weapon of espionage — an uncrackable code. The potential commercial and military applications of ...

When quantum computers become commonplace, current cryptographic systems will become obsolete. Scientists are racing to get ahead of the problem and keep our data secure.

While efforts in Europe focused on Enigma, the outcome of the Pacific War hinged on intercepting and breaking Japanese naval ...

Code-based cryptography is a promising branch of post-quantum cryptography that exploits the inherent complexity of decoding linear error-correcting codes. Traditional schemes, such as the McEliece ...

Ever since writing has existed, people have wanted to send secret messages to one another--and others have wanted to intercept and read them. This is the second installment of a blog series taking you ...

Two things jump to mind when it comes to encryption: It's a must-have for secure military installations, and it's a huge headache to implement among everyone else. Encryption's reputation as a ...

You might not have heard of OpenBSD, but the free operating system is at the root of many computers and virtual private networks worldwide. So too is the FBI -- that is, if you believe a new ...

Think about the humble envelope. For centuries this paper enclosure has shielded important information from prying eyes that might otherwise steal a glance at an unprotected note. Also, by placing ...
