Explore computer security fundamentals through this comprehensive video lecture series from Dalhousie University's ECED4406 course. Delve into the historical foundations of security by examining basic ciphers and the Enigma machine before progressing to modern computer security concepts. Learn about embedded systems security, industrial control systems, automotive security, and networking communications while considering the ethical implications of computer security practices. Master cryptographic principles including symmetric encryption, AES (Advanced Encryption Standard) and its various modes, RSA encryption, and common attack vectors against these systems. Develop reverse engineering skills by understanding the relationship between C code and assembly language, function calling conventions, binary formats, and using professional tools like Ghidra for binary analysis and function identification. Gain hands-on experience with side-channel attacks, particularly power analysis techniques, and learn how to exploit vulnerabilities such as Hamming weight variations and single-bit leakages to compromise AES implementations. Practice data analysis and visualization techniques using Google Colab and plotting tools to support your security research and analysis work.
