Selected Cryptographical Methods (KRY)

Protect Information with Cryptography: Deepen your understanding of modern cryptographic methods and protocols—from digital signatures and zero-knowledge proofs to elliptic curve cryptography and post-quantum cryptography—and learn to evaluate their security and applications.

Contents

• Topics include:
• Recapitulations of basics: symmetrical and asymmetrical algorithms, hash-functions, mathematical background
• Cipher Modes: ECB, CBC, CFB, OFB
• Digital Signatures, Blind Signatures
• PKI
• Information-theoretic security
• Basic protocols: Bit Commitment, Secret Sharing, Challenge-and-Response
• Zero-Knowledge Proofs
• Attacks on cryptographic protocols
• Elliptic curve cryptography
• Post-Quantum Cryptography

Competencies

Students are able to

• understand the principles of symmetric and asymmetric cryptographic systems.
• understand the operation of fundamental cryptographic protocols and zero-knowledge proofs.
• explain and present the acquired knowledge to colleagues without prior expertise in the subject.
