What is encryption
Transforming data with a mathematic algorithm
Data can only be read with a cypher
Used to keep info private
What is a key?
Random string of charactors
Used in conjuction with data and cypher to create unique data block
What is cipher text?
Encrypted block of data
What is a brute force attack
Attempt to break encryption by guessing keys
What is symmetric encryption
Also called private encryption or shared key
Same key is used to encrypt or decrypt data
Key must be known by multiple parties
What is asymmetric encryption
2 keys, know as key pair
One key encrypts one decrypts
Requires a public key server
What is a digital certificate?
Contains identification information about key owner and public key
What is central authority
Issues and maintains digital certificates
Public ca,s are trusted
