Abstract
This activity aimed to introduce the basic concepts of cryptography, particularly the Caesar Cipher and Vigenère Cipher, in a simple manner to fifth-grade students as an effort to raise awareness of the importance of personal data security from an early age. The implementation of the activity included the delivery of material, group work in creating and deciphering codes, and evaluation through observation and questionnaires. The results showed a high level of enthusiasm from the students and strong support from the school. The average assessment score was 3.6 (categorized as good), reflecting the effectiveness of the approach used. This activity made a tangible contribution to enhancing students’ digital literacy and opened opportunities for the development of follow-up programs, such as teacher training and the creation of learning media focused on digital security.
Keywords: cryptography; caesar cipher; vigenère cipher; digital literacy.
