Chapter 7: Cryptography - Types of Attacks

Ciphertext only Attacks - attacker has the ciphertext of many messages, and each is encrypted using the same encryption algorithm. Most common attack, but hardest to be successful.

Known Plaintext Attacks - Attacker has the plaintext and the ciphertext to messages.

Chosen Plaintext Attacks - attacker has plaintext and ciphertext, but chooses the palintext that gets encrypted to view the ciphertext.

Chosen Ciphertext Attacks - chooses ciphertext to be decrypted and then gains access to the plaintext

*Goal is to figure out the key

Social Engineering - Manipulating others in order to get them to provide information.
