Encryption
Bayani Gaba-gaba
Every time you log in to a bank or send a message, your data travels across networks where it could be intercepted. Encryption is the lock that keeps that data meaningless to anyone who steals it on the way. It does not stop a thief grabbing the data, it makes the stolen data useless.
In this lesson you will learn why encryption is needed, the difference between scrambled cipher text and readable plain text, and the two methods you must be able to describe: symmetric encryption, which shares one secret key, and asymmetric encryption, which uses a clever public and private key pair to keep the secret safe even on the open internet.
Manufura
- 1 Understand the need for and purpose of encryption when transmitting data
- 2 Understand how data is encrypted using symmetric and asymmetric encryption
