Cryptography and Network Security focuses on protecting information, computer systems, and communication networks against unauthorised access and attacks.
The subject is important because modern organisations depend heavily on secure digital communication.
Meaning of Cryptography
Cryptography deals with techniques used to protect information by transforming it into a secure form.
A simple concept is:
Plaintext → Encryption → Ciphertext
The authorised receiver can use an appropriate process to recover the original information.
Encryption
Encryption converts readable information into protected form.
It helps prevent unauthorised users from understanding sensitive data.

- public key
- private key
It can support secure communication and digital signatures.
Symmetric vs Asymmetric Cryptography
| Symmetric Cryptography | Asymmetric Cryptography |
|---|---|
| Uses shared secret key | Uses public-private key pair |
| Generally faster | Generally more computationally intensive |
| Key distribution can be difficult | Supports easier public-key distribution |
| Useful for bulk encryption | Useful for key exchange and digital signatures |
Hashing
A Hash Function converts input data into a fixed-size output.
Hashing can be used for:
- integrity verification
- password-related security mechanisms
- digital signatures
Hashing is different from encryption because it is generally designed as a one-way transformation.
Digital Signature

Authentication
Authentication verifies the identity of a user or system.
Examples may include:
- passwords
- security tokens
- multi-factor authentication
Authorization
Authorization determines what an authenticated user is permitted to access.
Authentication vs Authorization
| Authentication | Authorization |
|---|---|
| Verifies identity | Determines permissions |
| Answers “Who are you?” | Answers “What can you access?” |
| Happens first | Follows successful authentication |
Importance of Network Security
Network Security helps protect:
- confidential data
- organisational systems
- user accounts
- financial information
