Would you sacrifice one life to save a thousand? It is a morally stupefying question that has gone against our societies ethics. Do we favor the collective good over the good of the individual? However ambiguous the answer is during peace, I believe the answer is clear in wartime. The collective good takes precedent. Admiral […] Continue reading
As Singh deciphered the example of the Vigènere cipher on page 116, and also other ciphers previously, I contemplated just how simple he was making them. He makes a lot of assumptions, and he also never points out some flaws that I have seen in his messages. In the example on page 16, Singh uses […] Continue reading
Singh’s examples in book seem easy to comprehend. The methods are relatively straightforward and codes were broken within few pages of the book. However, in practice the process of cryptanalysis is usually much more complicated. I believe there are three reasons for that. First of all, the cryptanalyst has no idea what type of code […] Continue reading
Being completely honest, most of this talk went over my head. I tried to take notes as I was trying to take notes as I was listening, but they were speaking very quickly, and I couldn’t really comprehend what they were saying. This is my attempt at notes: First off, this talk has started out […] Continue reading
The strength of the Vigenère Cipher depends largely on the length of the keyword. If the keyword is just one letter, then it is nothing more than a simple shift cipher; if the keyword is the same length as the plain text, there will be little to no discernable pattern. However, Singh clearly demonstrates that even with […] Continue reading
I believe that the decision taken by Admiral William Hall was the right one, even though it was unethical. While it was morally wrong for him to let civilians die for a strategic gain, it was the right course of action to take for a man in his position. He was responsible for winning the […] Continue reading
Admiral William Hall decided to keep the information that the English broke the enciphered Zimmerman telegram a secret because he believed that the knowledge for decrypting the telegram would be an asset to the them in the near future. Those who were thoughtful of the future such as Admiral Hall would believe this choice to […] Continue reading
At the Brechley Manor, in addition to Knox, the deciphering community, there is also a mathematics wizard, Turing. He graduated from Cambridge University and relied on his research on cryptography after the war. He became one of the pioneers in the era of electronic computing. First of all, they started with the development of a […] Continue reading
In the movie “The Imitation Game,” there is a scene that Alan Turing and his team deciphered a message indicating that there is going to be an attack on the British Navy. After celebrating for finally able to beat the Enigma Machine made by Germany, they calmed down quickly and decided not to present the […] Continue reading
The former NSA and CIA director, General Michael V. Hayden, was interviewed by Chancellor Nicholas Zeppos and Professor Jon Meacham. Before going to the lecture, I thought that the interview’s going to be a debate of “Security versus Privacy.” However, it is more about political views and the current direction of the United States. During the […] Continue reading
