HYBRID DNA CRYPTOGRAPHY METHOD USING DIFFERENT KEY GENERATION TECHNIQUES

Nowadays, the large volumes of real-time data like structured and unstructured data are created by industries, hospitals, IT fields and so on. Day to day the data size is increased in the form of gigabyte or terabyte or pet a byte. All these big data contain confidential and sensitive information. They are communicated in an open-source network like an internet and stored in the cloud computing environment. The open-source network contains a lot of attackers and malicious users. They always attempt to access the confidential data without having the authorization of the right user. Sometimes they exchange the original data to fake data. So, the security of big data in open-source has become an important issue. DNA [Deoxyribonucleic acid] Cryptography is an advanced developed field for improving big data security which is developed based on the biological concept of DNA. In this paper, the data are encrypted with the hybridization of DNA Cryptography and the Insertion method. Here pseudo-random Number generator algorithm is hybrid with El-Gamal key generation to generate a key that enables the data to protect against many security attacks and share the key using a Shamir secret sharing. Finally, the experimental results as well as the security analysis show the better solution when compared to a well-known existing system.
