An Enhanced Bilateral Information Security towards a Conventional Cryptographic System using DNA Sequences

Objective: Information security is one of the essential futures challenged in data transmission through wireless networks. Networks are extremely exposed to security attacks and consign a great challenge today. Methods: In this paper we propose a new DNA Symmetric Cryptographic technique that employs Mathematical formula for encryption and decryption and private key is generated from blood analysis report. After Encryption DNA codons are generated as a cipher text which is decrypted through decryption algorithm into readable text. In this method we use classical cryptographic technique of substitution method in DNA Cryptography. Findings: The algorithm is implemented in Java Platform and comparison was prepared for encryption and decryption time for different file formats. Also size of encrypted file is also compared for different files. Improvement: DNA based approach which is more immune to cryptographic attacks. DNA Cryptography is a new and potentially excellent area that enhances data security. It helps to transmit highly confidential data efficiently and securely.
