AP CSP Exam Section 4 (Internet and Cybersecurity) with
all Correct & 100% Verified Answers |Already Graded A+
Caesar Cipher ✔Correct Answer-a technique for encryption that shifts the alphabet by some
number of characters
Cipher ✔Correct Answer-the generic term for a technique (or algorithm) that performs
encryption
Cracking encryption ✔Correct Answer-When you attempt to decode a secret message
without knowing all the specifics of the cipher.
Decryption ✔Correct Answer-a process that reverses encryption, taking a secret message and
reproducing the original plain text
Encryption ✔Correct Answer-a process of encoding messages to keep them secret, so only
"authorized" parties can read it.
Random Substitution Cipher ✔Correct Answer-an encryption technique that maps each letter
of the alphabet to a chosen other letters of the alphabet.
Vigenère cipher ✔Correct Answer-a method of encrypting text by applying a series of
alphabetical shifts based on the letters of a keyword.
asymmetric encryption ✔Correct Answer-used in public key encryption, it is scheme in which
the key to encrypt data is different from the key to decrypt.
modulo ✔Correct Answer-a mathematical operation that returns the remainder after integer
division.
Public Key Encryption ✔Correct Answer-Used prevalently on the web, it allows for secure
messages to be sent between parties without having to agree on, or share, a secret key. It uses
an asymmetric encryption scheme in which the encryption key is made public, but the
decryption key is kept private.
Key ✔Correct Answer-What tells you how to arrange the cipher's rules. _______ is applied
using an algorithm to a string or block of unencrypted text to produce encrypted.
Deciphering ✔Correct Answer-A class of ciphers where the code is based on one letter of the
alphabet standing for another letter consistently throughout the message
