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.

This is a PDF file of a chapter taken from a book that contains essays on many issues that arise from "big data." This chapter specifically pertains to our privacy versus security debate because it provides reasons as to why bulk data collection does not work as well as alternative options to mass surveillance.

Researchers have applied the microdot principle described by Singh on page 6 to hide messages in DNA sequences.

A brief look at the science of cryptology and the simple encryptions found in the Old Testament. Has a couple of examples and explains the three main transformations used.

A useful document detailing the different substitution ciphers (including the Caesar Shift) and the application of Modular Arithmetic in modern day Cryptography.

This website has lots of great information on historical ciphers such as the Voynich Cipher and the Dorabella Cipher.

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.

Cryptanalysis and Frequency Analysis

An in depth summary about Mary, Queen of Scots, and the people she encountered.

This website details how the Spartan scytale was used in 500 B.C. Also features a program that encodes your own message according to the spartan scytale.

An in-depth description of Julius Caesar's shift cipher and how it works. Also shows how to use frequency analysis and chi-square values to quickly break the cipher.

A breach in supposedly secure keys given to employees by private companies vindicates previous warnings by cryptographers that companies should use more difficult keys, and that companies have not been cautious enough using such keys because of their assumed security.

Very interesting article that begins with the story of Mary, Queen of Scots, and continues to speak about different techniques of encryption that are harder and harder to break. It also deals with the fact that Mary's messages were being intercepted and the article speaks about secure encryption using photons where you would know if your message was intercepted.

Many interesting ones in this list. I like the Kryptos at the CIA headquarters. 

Here's a list of 10 unsolved cipher texts throughout history, #2 is the Beale Papers covered in the chapter, #8 is Kryptos (the background of our website). Some date back as far as 1400 BC and some are more recent like the Zodiac Killer.

This is the e-text of a book that discusses online network encryption and application. The chapters cover various encryption methods for the transfer of data online, as well as the application of wireless, email, IP network security

"Signage can be an important legal component in the use of video cameras in schools. As mentioned in the previous section, it is important that the presence of video cameras not lead a person to believe he or she will be rescued if attacked."
