Design of DNA-based Advanced Encryption Standard (AES)

Abstract

DNA cryptography is a new promising direction in cryptography research that emerged with the progress in DNA computing field. Traditional cryptographic systems have long legacy and are built on a strong mathematical and theoretical basis. So, an important perception needs to be developed that the DNA cryptography is not to negate the tradition, but to create a bridge between existing and new technology. The power of DNA computing will strengthen the existing security systems by opening up a new possibility of a hybrid cryptographic system. In our work, we are presenting the DNA-based design and implementation to “Advanced Encryption Standard” [AES]. We built our algorithm with all its specifications (data, algorithms operations and used functions) on DNA basis instead of bits. This aims at proving the possibility of building such a complex system on DNA basis in a way of making it a suitable candidate for implementation in biological environment or on DNA computers. Our algorithm kept the same security strength and robustness of the standard algorithm.
