An Enhanced Hybrid Cryptosystem based on DNA Computing

Encryption is critical method to give secrecy while transmitting information over Internet. There are many methods used for encrypting and decrypting text message, image or other important data. This paper deals with a new hybrid cryptographic technique using combination of AES Algorithm and Elgamal cryptosystem based DNA computing. Further, this paper attempts to utilize the properties of DNA in encryption and decryption process with more efficient. The performance of the proposed scheme is compared with the existing cryptosystems. The steps of the implementation of our algorithm are also investigated.
