Abstract

This article describes Demitasse, a cipher that is intended to be used by inexperienced students in a classroom setting. The cipher is based on the Tiny Encryption Algorithm, but the parameters have been reduced in order to allow the students to operate the cipher with paper and pencil rather than a computer. Nevertheless, students using the cipher should gain some understanding into the inner workings of a modern computer cipher. An example of the use of Demitasse in the classroom is also discussed.
