ePrint Report: Comment on Enhanced DNA and ElGamal cryptosystem for secure data storage and retrieval in cloud

Chenglian Liu, Sonia Chien-I Chen

Thangavel and Varalakshmi proposed an enhanced DNA and ElGamal cryptosystem for secure data storage and retrieval in cloud. They modified ElGamal algorithm which it calls enhanced ElGamal cryptosystem. We prove that their enhanced ElGamal scheme, which does not require two random numbers by data owner. Although the attacker is unable to find out what message the data owner …
