Preparatory material

Preparation sheet

The preparation sheet (PDF) contains exercises to basics of public-key cryptography, lattice-based cryptanalysis and pairing-based cryptography.  It is strongly recommended that you make yourself familiar with the concepts covered in the sheet. The lecturers will not repeat all the details of these basic principles.  Note that the exercises are meant for your personal control only, it's your responsibility.

If you have questions concerning the sheet, please feel free to discuss them among all participants via the mailing list .

Additional material pairing-based cryptography

Students should be familiar with basic concepts in public key cryptography, such as definitions and examples of public key encryption and signature schemes. It would also be helpful if students already have an appreciation of security proofs in cryptography. Finally, students should be aware of the Random Oracle Model and its use.

Once you are logged in with your cosec web account, you can access extra features.

During the talks, I will be covering material from the following papers (and more!):
