Recent advances in genetic engineering have enabled the insertion, deletion and modification of original genome sequences of the living cells of organisms. Demand for data storage increases rapidly because of structured and unstructured data from the Internet of Things (IOT), sensors and Big Data. Information security has become a crucial need for almost all information transaction applications due to the large variety of hackers and attacks. Traditional techniques such as cryptography, watermarking and data hiding are basic notions and play an important role in developing information security algorithms and solutions. This chapter presents DNA XOR operation-based security and storage of encrypted data in a DNA format with long life, while maintaining artificially created DNA in specific laboratory conditions. We propose new encryption and decryption algorithms for data security and storage in DNA sequences with genes as keys. We can store 108 TB per 1 g of created cipher data with a life span of 4000 years. We demonstrate how to overcome the existing key length of 64, 128, 192, 256 bits and cryptanalysis of letters.
