I’m not often a fan of conspiracy theories, except for entertainment value. This one is interesting because it combines international intrigue, the elections, and our world of notoriously poor email security.
The conspiracy arises from foreigners trying to influence the United States election. They spy on unprotected emails and leak the contents to influence US public opinion. This isn’t limited to attacks on the Democratic candidate Hillary Clinton. Some suggest that Fox News and the Trump campaign have also been attacked this way.
We could be blocking this threat, except that pressure groups within the government want to leave as much information unprotected as possible, notably law enforcement and intelligence agencies. I think we face a greater threat from foreign exploitation of our unprotected emails than we face from impeded investigations or even a few terrorist bombs.

I’m a fan of Boak’s Lectures – they cover the fundamentals of military cryptography just before the information revolution.David Boak developed the lectures for the National Security Agency’s Cryptologic School.
Even though the lectures are from the ’60s and ’70s, they remain relevant to today’s cybersecurity threats. Cryptographic techniques that were classified Secret in Boak’s work are prominent in modern commercial cryptosystems. A sanitized version of Boak’s Lectures (Vol 1, Vol 2) was released in 2008.
I’m happy to report that the Interagency Security Classification Appeals Panel has released a more complete (less redacted) version. It’s available from the Government Attic.

Matthew Green published an entertaining rundown on the cryptographic back door in ANSI and NIST standards. He focuses on how it got there and why it’s still there, as opposed to its technical details.
The one-time pad is the only encryption technique that has been mathematically proven to be uncrackable. While hard to use, it has often been the choice for highly sensitive traffic. Soviet spies used one-time pads in the 1940s and -50s. The Washington-Moscow “hot line” also uses one-time pads. However, the technique is hard to use correctly.
