The Babington plot, which was the undoing of Mary, Queen of Scots, was one of several conspiracies against Elizabeth I that were uncovered. The Ridolfi Plot In 1571 a plot was discovered involving Philip II of Spain, Pope Pius V and the Duke of Norfolk, as well as Mary's advisor, the Bishop of Ross, and Mary herself.
This is a cryptography blogger's translation of Kerckhoff's article about military cryptography. He denotes that secret methods of communication are limited to higher officers due to potential leakage; but by limiting cryptographic use, are they potentially putting at risk the safety of lesser positions in order to keep the secrecy of their cipher methods? Is this just the inevitable nature of cryptography in general?
This resource provides access to articles, news, and blog posts regarding military embedded systems, often using cryptography. One article referenced the cryptography used to secure "Data at Rest" and the length at which this information should be held secure. Is it ethical to keep this information from the public when safety is no longer a concern? At what point should these well-kept secrets become accessible?
Embeddable cryptographic processors are enabling a host of new defense communications applications, such as smartphones and tablet computers for tactical use on the front lines, but should soldiers be using the same object for both secure and insecure communications? Or does this create a conflict of interests?
I'm just going to resubmit the bookmark directly to this page so I'll be sure it ends up publicly in the group.
This wasn't mentioned in Singh chapter 2, but it was created around the time period discussed in the chapter. (Plus, it's one of my favorite articles I've read in Wired so I really wanted to use it as a bookmark.) The article discusses the strategies used to break this cipher, some of which, such as frequency analysis, we have talked about in class. It's also just fascinating to read about the Oculists and their history.
A pre-WWII NSA document on advanced military cryptography which was declassified in 2014. This leads to the question of what impact disclosing these military secrets has on encryption and decryption of messages in future wars, and also why were these documents released in the first place.
