构建密码安全体系是保障信息安全的重要手段。密码安全体系的构建可以抽象为特殊的数学模型。从密码学发展与数学的关系入手,分析古代、近现代数学研究对密码学发展的推动与促进作用,并从当代数学研究发展方向的角度来预测现代密码学的发展趋势。 Building password security system is an important means to ensure the security of information. The construction of password security system can be abstracted as a special mathematical model. Starting from the relationship between the development of cryptography and mathematics, this paper analyzes the promotion and promotion of the development of cryptography by ancient and modern mathematics research, and forecasts the development trend of modern cryptography from the perspective of the development of contemporary mathematics.
