《信息安全數學基礎》課程介紹
信息安全是指信息系統（包括硬件、軟件、數據、人、物理環境及其基礎設施）受到保護，不受偶然的或者惡意的原因而遭到破壞、更改、洩露，系統連續可靠正常地運行，信息服務不中斷，最終實現業務連續性。信息安全主要包括以下五方面的内容，即需保證信息的保密性、真實性、完整性、未授權拷貝和所寄生系統的安全性。
《信息安全數學基礎》是網絡與信息安全專業的必修課。目的是學習和掌握信息安全所涉及的數學理論，主要是數論、代數和計算複雜度等數學理論，特别是學會用嚴格的數學語言對信息安全和密碼學所涉及的一些具體的數學理論給出了詳細的推理和說明，對關鍵技術涉及的算法給出适合計算機實現的描述，從而跟上信息安全和密碼學的最新進展，為從事相關的研究工作和工程實踐奠定基礎。
本課程第一學年第二學期開設，計劃學時64，先修課為：高等數學，離散數學。
Introduction to the course“Information security mathematical foundations”
Information security is refers to the information system (including hardware, software, data, people, physical environment and infrastructure) are protected, not by accidental or malicious destruction of, change, leak, a continuous and reliable system in normal operation, the information services are not interrupted, the final realization of business continuity. Information security mainly includes the following five aspects, namely, the need to ensure the confidentiality, authenticity, integrity, unauthorized copy and the parasitic system security.
Information security mathematical foundations is a compulsory course of network and information security specialty. Its objective is to study and master the mathematical theory related to information security, mainly number theory, algebraic and computational complexity theory, especially learn to use mathematical language strictly on information security and cryptology involved some specific mathematical theory gives detailed reasoning and description, suitable for computer implementation description of the algorithm is given, the key technology involved, so as to keep up with the latest advances in information security and cryptography, and lay the foundation for the related research work and engineering practice.
The course will be taught in the second semester of the first academic year, which includes 64 hours. Its prerequisite courses include advanced mathematics, discrete mathematics.
