Study Notes
Encryption Basics
- Original message is called Plaintext
- Coded message is called Ciphertext
Encryption and Decryption
- Process of converting Plaintext to Ciphertext is called Enciphering or Encryption
- Process of restoring Plaintext from Ciphertext is called Deciphering or Decryption
Cryptography and Cryptanalysis
- Cryptography is the area of study that deals with encryption schemes
- A Cryptographic System or Cipher is a scheme used for encryption
- Cryptanalysis is the study of deciphering a message without knowledge of enciphering details
- Cryptanalysis is also known as "breaking the code"
Importance of Encryption
- Encryption plays a crucial role in securing various IT assets
- Encryption provides:
- Confidentiality: encodes the message's content
- Authentication: verifies the origin of a message
- Integrity: ensures the message is not tampered with
