The integration and combination of an asymmetric and symmetric algorithm such as RSA, ElGamal, DSA, and AES were presented. Hybrid encryption has been used to ensure integrity in terms of data exchanged between the sender and receiver. The strength of the asymmetric algorithm such as RSA depends on the difficult process of factorization of large prime integers while the ElGamal’s security lies on Discrete Logarithm Problem (DLP). The symmetric algorithm is known to process the encryption faster than the asymmetric algorithm. Key generation of DSA is merged in the proposed algorithm. DSA is recognized for its fast signature algorithm while the AES S-Box is used to hash the ciphertext obtained. AES strength is its fast expansion key tone. Experiment’s result is presented to analyze the effectiveness of the proposed algorithm.
