Course description and aims

Cybersecurity is important for our daily lives including various types of activities. There is a growing demand for students who can be researchers and engineers capable of understanding cybersecurity.
In order to satisfy this demand, Tokyo Tech has launched Progressive Graduate Minor in Cybersecurity in April, 2016. We design the curriculum of Progressive Graduate Minor in Cybersecurity in collaboration with NRI as the core, also with Rakuten, NTT, AIST, and NISC. The following six courses are organized in School of Computing: Foundation of Cybersecurity (1Q, 2-0-0), Theory of Cryptography for Cybersecurity (3Q, 2-0-0), Cybersecurity Governance (3Q, 1-1-0), Attack and Defense on Cybersecurity I (2Q, 1-1-0), Attack and Defense on Cybersecurity II (3Q, 1-1-0), and Attack and Defense on Cybersecurity III (4Q, 1-1-0).
This course is one of the core courses in this minor. This course aims to help students to understand the theory of cryptography as a fundamental element of cybersecurity. In particular, this course mainly gives models, schemes, and security proofs appeared in the theory of cryptography related to cybersecurity.

Student learning outcomes

By the end of this course, students will be able to understand:
1) models in cryptography as a fundamental element of cybersecurity
2) systems and algorithms in cryptography as a fundamental element of cybersecurity
3) techniques for security proofs in cryptography as a fundamental element of cybersecurity.

Keywords

cryptography, security, information security, cybersecurity, security proof

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

The class offers a standard type of lecture.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

Textbooks will be used in this course.

Reference books, course materials, etc.

References will be announced in the classes.

Assessment criteria and methods

The evaluation consists of the reports as homework assignments. There will be approximately three reports. The weights of the scores of the reports are equal. The total score is calculated by adding all of the scores.
