Kombinasi Algoritma AES, RC4 Dan Elgamal Dalam Skema Kriptografi Hybrid Untuk Keamanan Data

COMBINATION ALGORITHM AES , RC4 AND ElGAMAL
CRYPTOGRAPHY SCHEME IN HYBRID
FOR DATA SECURITY

ABSTRACT

Delivery or exchange of data is something that often happens in the world of
information technology. Data sent sometimes often contain important
information data even highly confidential and must be safeguarded. To maintain
data security, can be done using cryptographic techniques. The data security
techniques layered security with a combination of symmetric cryptographic
algorithm Advanced Encryption Standard ( AES ) with RC4 by applying the
hybrid scheme, where data is encrypted with a symmetric algorithm while the
key is encrypted using a symmetric algorithm asymmetric algorithm or a public
key algorithm. Symmetric algorithm is an algorithm of encryption and
decryption using the same key. For the security of symmetric keys is done by
using a public key algorithm ElGamal .
