IAS1-Quiz No. 2 (final term) 6-9 late

It is the discipline of using codes and ciphers to encrypt a message and make it unreadable unless the recipient knows the secret to decrypt it.

• Cryptography

• Encapsulation

• Ciphertext

• Encryption

It is also called encryption algorithms.

• Cryptography

• Encapsulation

• Cipher

• Encryption

It is based on transposition and involves shifting each letter of the plaintext message by a certain number of letters, historically three.

• Keyword Cipher

• Caesar cipher

• Pigpen Cipher

• Atbash Cipher

What is the science of concealing messages with a secret code?

• Ciphertext

• Encapsulation

• Cryptography

• Encryption

It is used to determine the letter mapping

from plain to ciphertext. First, the repeated letters in the keyword

are removed, then the cipher alphabet is generated

• Keyword Cipher

• Caesar cipher

• Pigpen Cipher

• Atbash Cipher

It is a substitution cipher with a specific key where the letters of the

alphabet are reversed.

• Keyword Cipher

• Caesar cipher

• Pigpen Cipher

• Atbash Cipher

It is uses the same substitution across the entire message such as if you know that the letter A is enciphered as the letter K, this will hold true for the entire message.

• Monoalphabetic cipher

• Polyalphabetic cipher

• Polygraphic Cipher

• Encryption Algorithms

It is a table that allows someone to translate letters into numbers. To give a

small table level of encryption, this can be randomized and shared with the recipient.

• Keyword Cipher

• Polybius Square

• Pigpen Cipher

• Atbash Cipher

It is the way to encrypt and decrypt data which first it is about studying methods to keep a message secret between two parties , and the second is about the process itself.

• Cryptography

• Encapsulation

• Ciphertext

• Encryption

Who designed the Vigenère Cipher?

• Lock

• Chester Agarao

• Pascal

• Blasic de Vigenère
