Explores modern cryptographic and cryptoanalytics techniques in detail, and emphasizes how such mechanisms can be effectively used within larger security systems, and finding their vulnerabilities. Topics covered include cryptographic primitives, public key encryption, digital signature, message authentication codes, cryptographic protocols, and attacks.


The course focuses on foundations of modern cryptography. It introduces the basic requirements to cryptographic schemes, privacy and authenticity. The course then describes the main cryptographic primitives and demonstrates how they are used to construct private and public cryptosystems. We also consider how these constructions are used in the existing systems, and survey a number of modern applications of cryptography.



  • Basics of probability, cryptography, and complexity. Historical remarks
  • Concepts of privacy and authenticity
  • Cryptographic primitives
  • Private-key encryption: stream ciphers and block ciphers
  • Public-key encryption
  • Message authentication, digital signatures, and hashing
  • Selected topics: zero-knowledge proof, post-quantum cryptography, etc.
  • Survey of the cryptographic components of the existing protocols



Will be discussed in the first week of classes

Students must attain an overall passing grade on the weighted average of exams in the course in order to obtain a clear pass (C- or better).

Graduate Studies Notes:

Important dates and deadlines for graduate students are found here: http://www.sfu.ca/dean-gradstudies/current/important_dates/guidelines.html. The deadline to drop a course with a 100% refund is the end of week 2. The deadline to drop with no notation on your transcript is the end of week 3.

Registrar Notes:


SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html


Teaching at SFU in fall 2021 will involve primarily in-person instruction, with approximately 70 to 80 per cent of classes in person/on campus, with safety plans in place.  Whether your course will be in-person or through remote methods will be clearly identified in the schedule of classes.  You will also know at enrollment whether remote course components will be “live” (synchronous) or at your own pace (asynchronous).

Enrolling in a course acknowledges that you are able to attend in whatever format is required.  You should not enroll in a course that is in-person if you are not able to return to campus, and should be aware that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.

Students with hidden or visible disabilities who may need class or exam accommodations, including in the context of remote learning, are advised to register with the SFU Centre for Accessible Learning (caladmin@sfu.ca or 778-782-3112) as early as possible in order to prepare for the fall 2021 term.
