Syllabus

Start Here and Key Concepts of Information Security

This module provides an overview of the basic concepts of cryptography, including encryption, decryption, and cryptographic algorithms. It lays the groundwork for understanding the principles and practices of secure communication.

Number Theory

This module introduces various mathematical theorems related to number theory that are extensively used in asymmetric encryption algorithms.

Classical Encryption

This module delves into historical encryption methods such as Caesar cipher, monoalphabetic substitution, and transposition techniques. It explores their strengths and weaknesses, providing context for modern cryptographic techniques.

Symmetric Encryption and DES

Focusing on block ciphers, this module introduces DES as a foundational symmetric encryption algorithm. It discusses its structure, modes of operation, and its significance in cryptographic history.

Advanced Encryption Standard

Building upon the discussion of DES, this module introduces the AES algorithm, which has become the standard for symmetric encryption. It covers its design principles, security features, and its adoption as a global encryption standard.
