Computer security

What is the CIA triad (confidentiality, integrity and availability)?

Confidentiality, Integrity, Availability

Beyond CIA : Cyptography, Protocol Security, MAC(Media Access Control)

Error Detection Tech

BEC : Parity Checking, Check Sum Checking

FEC : Hamming code

Encryption and Decryption

Types of Cryptography

• Symmetric cryptography [private key] : 대칭형, 공통키 - DES(Data Encryption Standard)
• Asymmetric cryptography [public key] : 비대칭형, 공개키, RSA (Rivest–Shamir–Adleman)

Encryption Methods

• Substitution Cipher, Transposition Cipher, Product Cipher, Algebraic Cipher
