Encryption

Question	Answer
What is Encryption?	> Process of scrambling data so that is cannot be read by third parties > Done so by using a specific algorithm > Only the intended recipient should know how to decode the data
What is a Key in Encryption?	> A pair of very large prime numbers, usually 256 or 1,024 bits long, that the encryption algorithm depends upon to encrypt / decrypt data > It would take an impractical amount of time to guess the key
Why is Encryption Important in Wireless Communication?	> Wireless information can be intercepted by anyone, unlike wired communication, which requires a physical connection > Wireless protocols, such as WPA2, encrypt all traffic to prevent this
What is Symmetric Encryption?	> The same key is used to encrypt and decrypt data > This encryption is usually done via a cypher algorithm > Both the encrypted data and private key is transferred
What is the Problem with Symmetric Encryption?	> Anyone with the key can decrypt the data > The key could be intercepted to decrypt the data
What is Asymmetric Encryption?	> Uses two keys: a public key and a private key, related to each other through mathematical operations > The public key is given to the sender by the recipient > This public key is one-way, i.e., it can only encrypt and not decrypt the data > The private key can decrypt the data previously encrypted by the public key. This must never be shared.
