Handouts

All handouts in the course will be available here.

General Information

• Course description.
• Instructions for talks.
• Rules for solving problems and handing in solutions.

• Example of compiled solution set and the corresponding LaTeX source. Note that this is an example that should not be used to typeset any real set of solutions. It is only used to illustrate what is expected from students. There will be a separate template for each homework.

Latex and Running Ubuntu on Windows

• The Not So Short Introduction to LaTeX (see also the template above).
• VM Ware Player (free for non-commercial use)
• Download Ubuntu ISO-file
• ubuntu.tar.gz

To install Ubuntu in your VM Ware player, start the player, create a new virtual machine, and browse for the ISO-file. All you need to do is enter your name and password, the rest is taken care of by VM Ware player. When this is done you open a browser inside your Ubuntu and download ubuntu.tar.gz from this page. Look inside the scripts and comment out the things you do not want, the script is reasonably well documented.

Homework

• Homework 1. The notion of pseudo-random permutation used in Problem 8d) is the one where the adversary has access to two oracles: one for evaluating the permutation and one for evaluating its inverse. This corresponds to a cipher for which we can mount both chosen plaintext attacks and chosen ciphertext attacks. If only the permutation-oracle is available (and not the inverse-oracle), then three rounds suffice, so the distinction is important.
  
  The AES problem is on the Kattis server, but it is not visible as part of the Krypto15 course. I am not sure why this is and will investigate it.
  
  We thank Bastian Fredriksson for pointing out these issues.

• Lecture 14. Guest lecture by Mats Näslund, Ericsson Research. This is always interesting and appreciated by the students. Mats describes several real world examples of issues and solutions found in real mobile networks and covered in the course. He also describes the security solutions found in next generations' mobile networks.
