• Emma's blog with a 1-page overview about crypto resources. This blog at Norton360Online is educational, and avoids – to our knowledge – any 'marketing'. https://www.nortonsecurityonline.com/security-center/cryptography-resource-guide.html

• Website with nearly all in the GDR used codes and encrytion mechanisms – (only German) http://scz.bplaced.net

• Good reading introductionary paper by Scott Aaronson: "The Prime Facts: From Euclid to AKS" http://www.scottaaronson.com/writings/prime.pdf

• The Spy Camp ("Spioncamp") – (German only) https://ddi.uni-wuppertal.de/website/index-ddi.html

  The "Spy Camp" of the University of Wuppertal offers learning stations for cryptography and cryptology. These include ready-made station sheets, worksheets, solutions and templates for printing, which teachers and pupils can use to start immediately. It is primarily intended for Sek I, but parts can also be used in the lower school and in Sek II (High school level classes and Junior high school level classes).

• Educational project: "Zahlentheorie in der Schule – Von Primzahlen zur Verschlüsselung mit RSA" – (German only) http://www.hydrargyrum.de/kryptographie

• Teaching series: E-mail (only?) for you (Gramm et al., 2011)

  Here, the topic of encryption is dealt with in the context of "electronic mail". The aim of the teaching unit is to enable students to deal consciously and securely with the medium of e-mail. The principle of RSA encryption is made plausible to the learners at secondary level I with a minimum of mathematics. The means for this are on the one hand an animation on asymmetric encryption (see link) and the RSA demo from CrypTool 1.4.30.
