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 .
