Course information

• Lectures to date - grow with each class.
• Course information sheet. Please read it -  you are responsible for everything on it.
• Instructor: Viet Tung Hoang (Tung). Email: vhoang@fsu.edu. Office hours: Monday and Wednesday, 2:30 pm - 3:30 pm, virtual. See Canvas for Zoom link.  
  

Latex Resources

• Homework solution must be typed via LaTeX. LaTeX is the standard for typesetting scientific papers, and will likely come in handy outside CIS 5371.

• Homework template: Here's a Latex template (sample.tex, you need to right click the link and choose "Save link as") for typesetting homework and the pdf file (sample.pdf) that it produces. The file needs an image file ecb.pdf. The template also contains common notation  we'll see in class.

• Guides to using LaTeX: An introduction to LaTeX can be found here. Another guide can be found at Wikibooks.

• Online Environments: If you don't want to install LaTeX, ShareLaTeX and Overleaf are online environments which compile previews of your LaTeX documents as you type.

• LaTeX Editors: There are many LaTeX editors which allow you to use GUI to edit your LaTeX. LyX is a free one.

• Finding symbols: Detexify lets you draw the symbol that you are looking for and get LaTeX code. A static guide is here.

Online Crypto Resources

• Introduction to Modern Cryptography, accessible graduate lecture notes by Mihir Bellare and Phillip Rogaway.
• The Joy of Cryptography, undergraduate textbook by Mike Rosulek.
