Network Security

Spring 2026

Course Information

Discipline Sheet: FLT_NS_RO, FLT_NS_EN

Course Goal: This course covers emerging topics in cryptography closely related to cloud computing and network security: identity-based encryption, attribute-based encryption, searchable encryption, and homomorphic encryption. Pursuing doctoral studies in cryptography and information security is possible for those interested in deepening their understanding of the subject (please see the Students section on this site).

Student Resources: There is no textbook dedicated to this course. However, each lecture has a list of references that are easily accessible to all, and reading recommendations.

Lectures, office hours, exam sessions:

  • Teaching weeks and examination sessions: see the academic calendar at UAIC
  • Lectures: Tuesday, 18:00 – 20:00, in C309;
  • Office hours: Monday, 14:00 – 15:00, in 301;
  • Course and seminar resources are here, or see below.

Grading:

  • The final grade is based on scores from the ongoing evaluation and the final exam.
  • The instructor in charge of the laboratories will communicate the basic principles and the grading method to you during the ongoing evaluation. The ongoing evaluation score is measured on a scale from 0 to 100.
  • The final exam takes place in the examination session. The final exam score is measured on a scale from 0 to 100.
  • The course is passed if the ongoing evaluation and the final exam each score at least 45. If this requirement is met, the final score is computed as the average of the two scores. The final grade is then obtained by converting the final score (division by 10 and usual rounding).
  • Please note that the re-examination applies only to the final exam!
