Cryptography
About
The course is about the basic goals of cryptography (confidentiality, authentication, non-repudiation).
Symmetric key cryptography: block and stream ciphers, design principles and examples, modes of operation, message authentication codes.
Public key cryptography: asymmetric ciphers, signatures. Attack models and security notions.
Protocols for key management, authentication and other services.
