Course detail
Cryptologic Protocol Theory
FEKT-MPA-CPTAcad. year: 2022/2023
The course contains the introduction into advanced cryptography and provides the students with the information about basic cryptographic primitives and schemes. In particular, the commitment schemes, interactive proof systems, zero-knowledge protocols, sigma protocols, interactive and non-interactive proof of knowledge protocols, group signatures and advanced systems like eCash and attribute-based credentials are covered.
