CN02: Network Security (Q2/2020)

Course Goals

This course offers the fundamentals of the highly important topics in the computer networking – the network security. Students are required to take the L11 course to have basic concepts of networking, from application to link-layer layers.

After taking this course, students will be able to understand of (1) basic concepts of cryptography techniques, (2) application of cryptography in all layers of the Internet, including secure email, SSH, transport layer security, IPsec and wireless network security

    • Hardcover: (6ED) ~ 13,000 Yen

    • International ED: ~ 6,200 Yen (paperback)

    • Paperback (6ED): ~ 4,200 Yen (from India)

  • You can also use: Computer Networking: A Top-Down Approach by J.F. Kurose and K.W. Ross, any Edition is OK (this is the textbook of L11). But not all contents are available.

Grading Policy

  • A: Quiz submission (10%)

    • If you fail submit 4 or more quizzes in designated timing without prior permission: 0

    • Otherwise: 100

  • Q: Quiz answer: 10%

  • L: Lab assignments: (15x3) 45%
