Research of Combining Blockchain in the Course Reform of Cryptography by Experiential Teaching

Cryptography is the core of information security. Cryptography course is the central course in the construction of information security major. However, cryptography has a lot of theoretical knowledge, making students feel abstract and boring, and there is no suitable practical application, which leads to students' unsatisfactory learning effects. As the current advanced technology, blockchain is the perfect combination of cryptography and digital technology, but it is not integrated into the cryptography teaching. Therefore, in order to strengthen the training of information security talents, improve the effect of cryptography, and enhance students' interest in learning cryptography, this paper proposes a combination of blockchain technology for cryptography reform by experiential teaching, and the knowledge points in cryptography courses are targeted in learning in the blockchain. Taking the hash function in cryptography as an example, the “mining” of blockchain is experienced, and the important properties of the hash function, such as the antigenic image (unidirectional) and anti-collision, can deeply understood. At last, I hope to provide reference and new ideas for the construction of information security majors and training talent.
