A Novel Level-Based DNA Security Algorithm Using DNA Codons

Abstract

Providing security to the information has become more prominent due to the extensive usage of the Internet. The risk of storing the data has become a serious problem as the numbers of threats have increased with the growth of the emerging technologies. To overcome this problem, it is essential to encrypt the information before sending it to the communication channels to display it as a code. The silicon computers may be replaced by DNA computers in the near future as it is believed that DNA computers can store the entire information of the world in few grams of DNA. Hence, researchers attributed much of their work in DNA computing. One of the new and emerging fields of DNA computing is DNA cryptography which plays a vital role. In this paper, we proposed a DNA-based security algorithm using DNA Codons. This algorithm uses substitution method in which the substitution is done based on the Lookup table which contains the DNA Codons and their corresponding equivalent alphabet values. This table is randomly arranged, and it can be transmitted to the receiver through the secure media. The central idea of DNA molecules is to store information for long term. The test results proved that it is more powerful and reliable than the existing algorithms.
