Cryptography and Data Protection
Advanced concepts in cryptography focus on the role of encryption in securing data across various states and the implementation of key management practices. Different encryption techniques, including symmetric and asymmetric methods, along with hash functions and digital signatures, are explored. The chapter emphasizes the importance of strong key management and awareness of common cryptographic attacks to reinforce security measures.

What we have learnt
- Cryptography ensures confidentiality, integrity, and authentication.
- Symmetric encryption is faster, while asymmetric encryption is more secure for key exchange.
- Digital signatures and certificates validate identity and prevent tampering.
- Strong key management is essential for effective cryptographic protection.
- Awareness of cryptographic attacks helps reinforce defenses.
Key Concepts
- -- Symmetric Encryption
- A type of encryption where the same key is used for both encryption and decryption.
- -- Asymmetric Encryption
- An encryption method that uses a public key for encryption and a private key for decryption.
- -- Hash Functions
- Functions that produce a fixed-size hash value from input data, demonstrating a one-way transformation without decryption.
- -- Digital Signatures
- A cryptographic mechanism that confirms the integrity and authenticity of a message.
- -- Key Management
- The process of handling cryptographic keys throughout their lifecycle, including generation, distribution, storage, and revocation.
