Abstract: Cryptography is abstract and difficult to understand, more in teaching. The cryptography experiments website can reduce the understanding difficulties and achieves a telling effect. Based on the teaching reality of introduction to information security, this paper analyzes the existing problems from both teaching theory and practice, and introduces the development of a ASP.〖KG-*3〗NET website to address these issues. As well as take a RSA communication case to introduction the typical application of the system, the teaching effects based on the experiments website are also discussed.

Key words: information security, cryptography, experimental website, ASP.NET, experimental teaching
