Now a day everyone wants to provide security to their data. Present days many methods are available for doing the Cryptography. DNA sequence key based cryptography became popular because of its more security features. In the paper, encryption technique proposed is based on using two methods: Quantum key distribution for generating a key corresponding to the bit of the plain text and DNA sequence based encryption for encryption of the plain text. Sender first performs complement and LBP operation on the data. Instead of sending the processed plain text bits, sender sends the complement of the key if the processed plain text bit is 0 otherwise sends the swapped key sequence. DNA Complement method on the key which is generated by the Quantum key generation method is done based on BB84 protocol. Two step encryption and decryption technique using DNA based encryption is proposed and practically implemented. The performance of the proposed technique is analysed and compared with other related techniques
