After completing this course, the student should be able to:

Explain and describe core cryptographic principles, their historical development, and the role of probability in secure design.
Explain and apply symmetric cryptography concepts, including basic cryptanalysis of simplified or historical ciphers.
Describe and evaluate techniques in asymmetric cryptography and the principles behind advanced cryptographic protocols.
Demonstrate implementation, testing, and analysis of cryptographic methods or attacks in a lab setting.

Foundations of Cryptography: Cryptography as a tool for information security; historical context; theoretical underpinnings, including perfect secrecy and randomness; basic probability theory relevant to cryptography.
Symmetric Cryptography and Cryptanalysis: Stream ciphers (linear and non-linear feedback shift registers), block ciphers (Feistel networks and other designs), cryptographic modes of operation, and introductory cryptanalysis methods for breaking or assessing historical/simplified ciphers.
Asymmetric Cryptography and Advanced Protocols: Public-key encryption (e.g., RSA), key distribution concepts, digital signatures, cryptographic hash functions, quantum cryptography, zero-knowledge proofs, and examples of modern protocols, including post-quantum cryptographic methods.
