Cryptography and System Security (CSC604) and System Security Laboratory (CSL604) are core subjects in the Third Year (Semester VI) of the Computer Engineering curriculum at the University of Mumbai. These courses provide foundational knowledge of secure communication, cryptographic algorithms, network security protocols, and techniques to protect systems from various threats.
The curriculum encompasses several key domains in Cryptography and System Security:
- Introduction to Cryptography: Goals of security, security attacks, services, and mechanisms.
- Classic Encryption Techniques: Substitution and Transposition ciphers (Caesar, Playfair, Hill, Vigenere).
- Block Ciphers & Public Key Cryptography: DES, AES, RSA, Diffie-Hellman Key Exchange.
- Hash Functions & Digital Signatures: MD5, SHA, HMAC, Digital Signature Standard (DSS).
- System Security: Intruders, Malicious Software, Viruses, Firewalls, and Trusted Systems.
- Network Security Protocols: SSL/TLS, IPSec, PGP, Kerberos.
This repository represents a curated collection of study materials, reference books, lab experiments, and personal preparation notes compiled during my academic journey. The primary motivation for creating and maintaining this archive is simple yet profound: to preserve knowledge for continuous learning and future reference.
As a computer engineer, understanding security principles is crucial for building robust and secure systems in an increasingly interconnected world. This repository serves as my intellectual reference point: a resource I can return to for relearning concepts, reviewing methodologies, and strengthening understanding when needed.
Why this repository exists:
- Knowledge Preservation: To maintain organized access to comprehensive study materials beyond the classroom.
- Continuous Learning: To support lifelong learning by enabling easy revisitation of fundamental security concepts.
- Academic Documentation: To authentically document my learning journey through Cryptography and System Security and System Security Laboratory.
- Community Contribution: To share these resources with students and learners who may benefit from them.

Tip
Lab Insight: This laboratory curriculum progresses from implementing core cryptographic primitives (Substitution, RSA, Hashing) to practical network security operations (Reconnaissance, Sniffing, Spoofing). Mastering the underlying algorithms is just as critical as understanding how to deploy and defend against network-based attacks.
