Research on DNA Cryptosystem Based on DNA Computing

As a new type of cryptography, DNA cryptography generally uses DNA molecule as the information carrier and biological technology as the implementation tool. Due to its prominent advantages such as large storage capacity, high parallel computing, low energy consumption and abundant resources in nature, DNA cryptography has attracted wide attention. DNA cryptography involves biology, computer, mathematics and other disciplines. On the basis of the traditional cryptosystems, DNA molecular computing methods are combined to form a more reliable and stable new cryptosystems, which brings opportunities and challenges to the modern cryptosystems. This paper depicts several DNA cryptosystems, further analyzes the security and performance of these schemes, summarizes the shortcomings of current DNA cryptography research, and looks forward to its development prospect in the field of information security.
