Ethics in Wartime

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

Is cryptanalysis really as easy as Singh makes it seem?

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

Why Cryptanalysis Seems Easier Than It Actually Is

Singh’s examples in book seem easy to comprehend. The methods are relatively straightforward and codes were broken within few pages of the book.

General Michael V. Hayden: The Assault on Intelligence

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.

Breaking (Almost) Unbreakable Ciphers

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

Ethics Versus Strategy

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.

How was the German cipher deciphered in World War II?

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

Insightful ideas provided by General Hayden

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
