Encryption
Fichas del conjunto (6)
- 1What 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 - 2What 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 - 3Why 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 - 4What 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 - 5What is the Problem with Symmetric Encryption?> Anyone with the key can decrypt the data
> The key could be intercepted to decrypt the data - 6What 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.
