Encryption
Understand how encryption secures communication within Kerberos by transforming plaintext into ciphertext using symmetric keys and algorithms. Learn about data confidentiality in transit, encryption methods like the XOR cipher, and how keys enable authorized decryption. This lesson helps you grasp the fundamental encryption concepts essential for network authentication security.
We'll cover the following...
Kerberos adds privacy (confidentiality) and integrity in communication between entities using the protocol through encryption and checksums. Let’s look at each a little closer.
Encryption
Casually speaking, encryption is a way to conceal information by altering it so that it appears to just be random data. In computing, unencrypted data is known as plaintext, and encrypted data is known as ciphertext. The methods used to encode and decode messages are called encryption algorithms or ciphers. Encryption takes readable data and alters it so that it appears random. Although encrypted data appears random, ...
