The main cryptographic tools and primitives, their use in cryptographic applications; security and weaknesses of the current protocols. The notion of security, standard encryption schemes, digital signatures, zero-knowledge, selected other topics.


This course focuses on cryptographic primitives and cryptosystems underlying secure communication and information protection. We will study private-key and public-key encryption, authentication, digital signatures, and commitment schemes, and see how they are used in practice, analyse what it means for them to be secure, and look at why widely-used schemes such as SSL may be insecure. We will cover a range of cryptographic applications from wifi protocols to electronic voting and blockchains.


  • Basic cryptographic primitives and respective computational assumptions
  • Private-key encryption, block ciphers
  • Public-key encryption, certificates and certificate authorities
  • Message authentication, digital signatures and hashing
  • Secure communication protocols
  • Commitment schemes, blockchains
  • Time permitting: post-quantum cryptography



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).

Registrar Notes:


SFU’s Academic Integrity website 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
