1, computer network
Including the definition, composition and function of computer network, as well as the basic concepts such as the classification and topological structure of computer network. This paper introduces the basic concepts and protocols of physical transmission medium and physical layer of computer network. This paper introduces the basic concept of data link layer, error detection and correction technology, and data link layer protocols such as Ethernet and wireless LAN.
2. Mathematical basis of information security
Including prime numbers, modular operations, Euclid algorithm, extended Euclid algorithm, Euler function, etc. These number theory concepts play an important role in encryption algorithm. Discrete mathematics, including set theory, graph theory and logic. The concepts and methods of discrete mathematics are widely used in cryptography and network security.
3. Password system
Including the basic concepts of symmetric cipher and asymmetric cipher, encryption algorithm and decryption algorithm. It also includes basic cryptography knowledge such as message authentication code, digital signature and key exchange. Including random variables, probability distribution, conditional probability, statistical inference, etc. This knowledge plays an important role in cryptanalysis and security protocol design.
Introduction to Cyberspace Security;
1, culture target
The major of cyberspace security aims to cultivate professionals with good ideological and moral cultivation and social responsibility, master humanities and social sciences, and be able to engage in scientific research, design and development, service management and comprehensive application in cyberspace security-related fields such as politics, production, study, research and application.
2. Professional courses
Professional education focuses on programming, data structure, computer network, computer composition principle, operating system, database principle, cryptography and network security, and covers cryptanalysis. Through comprehensive practice and engineering practice, students' practical ability is strengthened and their comprehensive quality is comprehensively improved.
3. Employment direction
Cyberspace security professionals can engage in national defense undertakings such as electronic countermeasures and cyber countermeasures in government, military, public security, judicial and other state organs, and engage in education and other businesses in educational and scientific research industries such as schools, scientific research institutes and training institutions, with wide employment and many choices, and very broad career prospects.
