A type of cipher that takes a predetermined number of bits in the plaintext message
(commonly 64 bits) and encrypts that block - correct answer Block cipher
A type of cipher that encrypts each bit in the plaintext message, 1 bit at a time - correct
answer Stream cipher
A set of symmetric block ciphers endorsed by the US government through NIST. Shares
the same block modes that DES uses and also includes other modes such as XEX-
based Tweaked CodeBook (TCB) mode - correct answer AES
Also known as public key cryptography, this method uses two keys: a public key and a
private key. - correct answer Asymmetric key cryptography
