随着DNA计算的进步，基于DNA的密码学成为一个新兴的交叉学科研究领域。在本文中，我们提出了一种新颖的利用DNA自组装结构的DNA密码学。利用立足点链识别和链置换，以逐位异或（XOR）运算的形式实现一次性密码本形式的信息加密和解密。该系统的安全性主要源于DNA分子的物理隔离和特异性。该系统通过复杂的DNA自组装构建，其中利用荧光检测技术来实现信号处理。在所提出的DNA密码学中，每个比特的异或运算都是单独进行的，因此加密和解密过程可以大规模并行进行。这项工作可能表明DNA密码学在信息安全领域具有巨大的潜在应用。
With the progress of DNA computing, DNA-based cryptography becomes an emerging interdisciplinary research field. In this paper, we present a novel DNA cryptography that takes advantage of DNA self-assembled structure. Making use of the toehold strands recognition and strand displacement, the bit-wise exclusive-or (XOR) operation is carried out to fulfill the information encryption and decryption in the form of a one-time-pad. The security of this system mainly comes from the physical isolation and specificity of DNA molecules. The system is constructed by using complex DNA self-assembly, in which technique of fluorescent detection is utilized to implement the signal processing. In the proposed DNA cryptography, the XOR operation at each bit is carried out individually, thus the encryption and decryption process could be conducted in a massive, parallel way. This work may demonstrate that DNA cryptography has the great potential applications in the field of information security.
