Cryptography is just about as old as written communication itself, and mathematics has long supplied methods for the cryptographic toolbox. Starting in the 1970s, increasingly sophisticated ...

Introduction to ciphers and substitution. Alice and Bob and Carl and Julius: terminology and Caesar Cipher ; The key to the matter: generalizing the Caesar Cipher ; Multiplicative ciphers ; Affine ...

It all begins with mathematics really - the one true scientific language, so they say. Cryptography has been around as early as 4000 years ago, doing what it still does today - ensuring that secrets ...

"Large bureaucracies, with the power that the computer gives them, become more powerful," said New York Times reporter David Burnham in a 1983 C-Span interview about his book The Rise of the Computer ...

Mathematicians are often stereotyped as strictly logical, almost robotic, allowing no time for emotions to affect their work. For Daniel Larsen, this has never been true — in fact, it’s been the ...

In mathematics, proofs can be written down and shared. In cryptography, when people are trying to avoid revealing their ...

Two popular AES libraries, aes-js and pyaes, “helpfully” provide a default IV in their AES-CTR API, leading to a large number of key/IV reuse bugs. These bugs potentially affect thousands of ...
