“…As the platform is free for all, we note that it is also a financially Third, Scratch currently has several extensions related to educational modules such as Artificial Intelligence, Machine Learning, and Embedded Programming. Currently, these efforts have not yet included cybersecurity even though several works [42]- [48] demonstrate that we can effectively teach cybersecurity concepts through gamification and visual feedback (both features of Scratch). This work intends to address this gap by implementing the first Scratch extension for cybersecurity dedicated to cryptography.…”

The world continues to experience a shortage of skilled cybersecurity personnel. The widely accepted solution for reducing this gap is raising awareness about cybersecurity. In response, many schools are integrating cybersecurity into the K-12 curriculum. Also, educational initiatives from the National Initiative for Cybersecurity Education, GenCyber, and the CryptoClub project enable universities to provide enrichment to middle-and high-school students regarding the importance of cybersecurity. Unfortunately, there is currently an absence of visual and straightforward tools that limits the feasibility of hands-on practice during these initiatives. This paper presents the design, implementation, and evaluation of a new framework called CryptoScratch, which extends the Scratch programming environment with modern cryptographic algorithms (e.g., AES, RSA, SHA-256) implemented as visual blocks. Using the simple interface of CryptoScratch, K-12 students can study how to use cryptographic algorithms for services like confidentiality, authentication, and integrity protection; and then use these blocks to build complex modern cryptographic schemes (e.g., Pretty Good Privacy, Digital Signatures). In addition, we present the design and implementation of a Task Block that provides students instruction on various cryptography problems and verifies that they have successfully completed the problem. The task block also generates feedback, nudging learners to implement more secure solutions for cryptographic problems. An initial usability study was performed with 16 middle-school students where students were taught basic cryptographic concepts and then asked to complete tasks using those concepts. Once students had knowledge of a variety of basic cryptographic algorithms, they were asked to use those algorithms to implement complex cryptographic schemes such as Pretty Good Privacy and Digital Signatures. Using the successful implementation of the cryptographic and task blocks in Scratch, the initial testing indicated that ≈ 60% of the students could quickly grasp and implement complex cryptography concepts using CryptoScratch, while ≈ 90% showed comfort with cryptography concepts and use-cases. Based on the positive results from the initial testing, a larger study of students is being developed to investigate the effectiveness across the socioeconomic spectrum.
