Text

'An Introduction to Mathematical Cryptography', Hoffstein, Pipher and Silverman, Second edition.

PDF version available for free here with Brown University credentials

Homework policy

Homework comprises 20% of the course grade. It is posted on the course website and is due in class, at the beginning of class, on Fridays in general. No late HW will be accepted for any reason. Instead, I will drop your lowest two HW scores when computing your course grade.

Resources

Joseph Silverman has a mathematical cryptography calculator available here: it computes GCDs, inverses and powers modulo 'm', etc. Feel free to use this while doing homework assignments after Chapter 1, unless indicated otherwise on a problem.

Python for non-programmers if you want to learn to program
