ABSTRACT

The Data Encryption Standard (DES) was one of the most widely used modern algorithms particularly in financial applications. DES is no longer considered a secure algorithm. However, DES remains important to study as it has similar encryption principles to its successors triple DES and the Advanced Encryption Algorithm (AES). One approach to help students learn the DES algorithm is through simulation. This paper aims to identify the effective type of attention cueing for DES simulation. Two mock-ups designed using color and animated arrows as cueing were demonstrated to students for feedback. The result shows that both color and animated lines cueing used in the mock-ups helped students understand one of the DES processes represented by the mock-ups. Although the students’ preferences split as half students prefer color cueing while the rest likes animated lines better, our observation indicates that animated lines were the better cueing at guiding the students in learning.
