Encryption/Decryption

Question 1

Encryption

Answer 1

Taking a message and disguising it, where the sender and the receiver are the only ones who can decipher it.

Question 2

Decryption

Answer 2

A message being converted from encrypted to the normal message.

Question 3

Cipher

Answer 3

A disguised message

Question 4

Plain Alphabet

Answer 4

The regular alphabet

Question 5

Plain message

Answer 5

Original message with no encryption

Question 6

Cipher Alphabet (Shifted Alphabet)

Answer 6

The alphabet that replaces the normal alphabet in the plain message to create the Cipher message.

Question 7

Cipher message

Answer 7

The plain message that is encrypted with the Cipher Alphabet.

Question 8

Key

Answer 8

A piece of information the sender and receiver share, to do the algorithm, to figure out the plain message.

Question 9

Substitution Cipher

Answer 9

Substitution the normal alphabet with cipher alphabet with a different letter.
Ex. R -> Q, A->C, F->P

Question 10

Caesar Cipher

Answer 10

Type of Cipher alphabet where the plain Alphabet is shifted down a certain number of units to create a Cipher Alphabet.

Question 11

Random Substitution Cipher

Answer 11

Cipher alphabet with no pattern(randomly mixed, no shift)

Question 12

Frequency Analysis

Answer 12

Analyzing the frequency of letters in a cipher message

Question 13

Key exchange problem

Answer 13

A problem that occurs when two people send two keys and a message that gets intercepted.

Question 14

Symmetric encryption

Answer 14

Encryption that uses the SAME KEY to encrypt and decrypt the message.

Question 15

Public Key Encryption (asymmetric)

Answer 15

When the sender and receiver BOTH HAVE A PRIVATE KEY and PUBLIC KEY, both helping the decrypt and encrypt the message. If the sender uses the reciever’s public key to encrypt the message, the recipient’s private key is needed to decrpyt the message.

Question 16

Public Key

Answer 16

A key that is sent to the receiver, but is available to the public and can be viewed by everyone.

Question 17

Private Key

Answer 17

A key kept to yourself.

Question 18

RSA encryption

Answer 18

Encryption similar to public key exchange, but both the public and private key (only 2 keys) can encrypt the message, but the opposite is needed to decrypt it. If B encrypts the message using A’s public key, than A’s private key is needed to decrypt it.

Question 19

Unreasonable problem

Answer 19

A problem that’s unreasonable and isn’t necessary.

Question 20

AES encryption

Answer 20

A symmetric block cipher used by the US government to protect classified information, using 128, 192, and 256 bit keys to create the cipher and cipher text.

Question 21

Protocol

Answer 21

A set of instructions or rules someone/something follows to complete a certain task(similar to an algorithm).

Question 22

Digital Certificate

Answer 22

Certificates/ confirms the AUTHORITY AND IDENTITY of a website, individual, organization, user, device or server. Also validates the OWNERSHIP OF ENCRYPTION KEYS.

Question 23

Certificate Authority (CA)

Answer 23

They issue digital certificates that validate ownership of encryption keys used in secure communications. They are based on a trust model.

Question 24

SSL (secure sockets layer)

Answer 24

The protocol used for digital certificates.

Question 25

HTTP

Answer 25

Hypertext Transfer Protocol. a protocol for a browser that is used in a browser or website to exchange information.

Question 26

HTTPS

Answer 26

Hypertext Transfer Protocol Secure. A combination of HTTP and SSL or transport layer security (TLS).
