b. AES
c. RSA
d. 3DES

Answer 1

The IT director asks you to set up a system that will encrypt credit card data. She wants you to use the most secure symmetric algorithm with the least amount of CPU usage. The algorithms that we should select is AES Advanced Encryption Standard

Explanation:

• The AES is also referred to as Advanced Encryption Standard, it is also known as  Rijndael

• AES is a specification standard that is used for the  encryption of electronic data .

• It was established by the U.S. National Institute of Standards and Technology in the year  2001

• AES is a symmetric block cipher which encrypts the plain text and converts it into cipher text which consist of random characters.Only the individual having the special key can decrypt it .

• AES uses a type of symmetric key encryption, which indicates the  use of one secret key to cipher and decipher information.

• The Advanced Encryption Standard is used by the  U.S. government to protect classified information and is used to encrypt sensitive information

AES comes in 128-bit, 192-bit, and 256-bit variants and AES 256 provide you the highest level of security
