摘　　要：作为密码学近年来衍生出的全新分支,DNA密码学诞生自DNA计算,以DNA分子为信息载体,充分利用DNA分子所具有的超高存储密度、超大规模并行运算能力、超低能耗等优点,可从分子水平实现加密、隐写及签名认证等功能.经过二十余年的发展,DNA密码学也从理论初步走向应用,研究贴近研究热点,比如结合图像加密的混合加密、用于签名认证的DNA水印技术等.DNA密码学是对基于数学难题的传统密码学的有益补充,但仍处于起步阶段,基于DNA分子的加密、隐写、签名认证等技术都具有很大的发展空间.DNA密码学仍未建立起完备的理论体系,发展也受到生物技术的制约.随着生物技术的进步,DNA密码学一定能在信息安全领域展示出自己巨大的潜力和能量.As a new branch of cryptography derived in recent years,DNA cryptography was born from DNA computing,it uses DNA molecules as information carriers,and makes full use of the advantages of ultra-high storage density,ultra-large-scale parallel computing capabilities,and ultra-low energy consumption of DNA molecules.Encryption,steganography and signature authentication can be realized at the molecular level.After more than two decades of development,DNA cryptography has also gradually moved from theory to application,and research hotspots,include hybrid encryption combined with image encryption and DNA watermarking technology for signature authentication.DNA cryptography is a useful supplement to traditional cryptography based on mathematical problems,but it is still in its infancy,and technologies such as encryption,steganography,and signature authentication based on DNA molecules have great room for development.DNA cryptography has not yet established a complete theoretical system,and its development is also constrained by biotechnology.With the advancement of biotechnology,DNA cryptography can also show its great potential and energy in the field of information security.
