Materi Kuliah Keamanan Jaringan [part2]

Masih mengulas tentang materi kuliah Keamanan Jaringan di STMIK AMIKOM Purwokerto, dengan dose Ibu Swahesti.
Kali ini temen-temen bisa belajar tentang Chryptograph dan Authentication.

~~ Cryptography Definitions
Encryption is a process by which a message (called plaintext) is transformed into another message (called ciphertext) using a mathematical function and a special encryption password (called a key).
Decryption is the reverse process: transforming a ciphertext message back into its original plaintext form using a mathematical function and a key.
The mathematical functions and keys used for encryption and decryption may be the same, or may be different. ~~

~~ Authentication Definitions
Authentication is the process of proving one’s identity to someone else.
There are three main ways of authenticatingan individual:
- Something you own : A physical key, security card or badge, or a one-time password generator.
- Something you know : A password, cryptographic key, or the correct answer to a challenge-response test.
- Something you are : Some biometric measurement (facial features, fingerprint, retina scan, voice print, and so on), plus a liveness test.
For a network, we need an authentication protocol during communication when direct proof cannot be given. ~~

Itu penjelasan singkat tentang Cryptography dan Authentication, untuk lebih jelas dan detail temen-temen bisa download dan pelajari langsung.
