Principles and Methods in Cryptographic Security

Advanced Encryption Standards (AES)
• The AES is block cipher that is
symmetric.
• It is chosen by the government of
US
• The AES protects information that
are classified (Kumar &
Rana,2016).
• It is implemented in hardware

Data Encryption Standards (DES)
• The DES is a symmetric key
method that is outdated.
• The DES uses same keys in order
to decrypt and encrypt a
message (Aljawarneh &
Yassein,2017).
• In DES, private key is used.

3 Data Encryption Standards (3DES)
• 3DES is a kind of computerized
cryptography.
• The algorithms of block ciphers
are applied three times (Patil et
al.,2016).
• The size of key in increased.
