To ensure compatibility with their flagship product, the security engineer is tasked to recommend an encryption
cipher that will be compatible with the majority of third party software and hardware vendors. Which of the
following should be recommended?
AES (Advanced Encryption Standard) has been adopted by the U.S. government and is now used worldwide. It
supersedes the Data Encryption Standard (DES) which was published in 1977. The algorithm described by
AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.
AES is used to encrypt data, not to verify data integrity.
