Study Notes
Data Security
- Keeping data confidential is crucial for businesses to stay competitive in today's environments.
Cryptographic Hash Function
- A cryptographic hash function takes noise from a physical source and "distills" it to make every bit depend on every other bit.
Public-Key Cryptography
- Key lengths used in public-key cryptography are typically much longer than those used in symmetric ciphers.
Classical Encryption
- In classical encryption, the same letter can be encoded differently at different parts of the message, such as the letter A being encoded as the letter K and then as the letter W.
