摘要
ElGamal公钥密码算法在"密码学与网络安全"课程体系中占有重要的地位,本文提出了一种针对El Gamal密码算法的教学设计,充分挖掘Diffie-Hellman密钥交换协议在该算法中所扮演的角色,以问题导向为牵引,引发学生对El Gamal密码算法的思考,使得学生对El Gamal密码算法有了更加清晰的理解和深刻的认识,激发学生的学习兴趣。
El Gamal public key crypto algorithm plays an important role in cryptography and network security related curriculum. In this paper,we propose an instructional design for El Gamal cipher algorithm,which fully exploits the role of Diffie-Hellman key exchange protocol. Our design is problem-oriented,which causes students' thoughts on El Gamal algorithm,and makes the students have a clear and profound understanding of the cipher algorithm,thus arousing the students' interests in studying.
