Abstract:
Security is necessary for to protect the
information transmission. Cryptography is the process of
encryption and decryption a message for data security (such as
symmetric and asymmetric cryptography). In this system,
symmetric key cryptography and cryptography key usage based
on control vector. Each cryptographic key has an associated
control vector that defines the permitted use of the key within the
cryptographic system. In this paper, this use of control vector in
crypto systems based on hash function (MD5) and Advanced
Encryption Standard (AES).
