A new cryptography learning module, NgeXTEA, has been developed and applied to enhance teaching on the Information Security course. The module, NgeXTEA, is intended to deal with the lack of easy-to-understand teaching aids particularly for symmetric cryptography, which requires students to have extensive mathematical skills. The module was assessed by experts in terms of the validity of the learning module and the validity of the associated manual. In addition, the module was also measured in terms of ease of use from the student perspective. Overall, both evaluations show that NgeXTEA meets standard requirements as an appropriate learning module and it is found useful in enhancing students’ understanding of symmetric cryptography.
