中文摘要：

DNA 密码学当信息搬运人和现代生物技术是被使用，一块新出生的密码的地与 DNA 计算， DNA 在被使用的研究被出现实现工具。广阔并行和在 DNA 分子固有的非凡的信息密度为象加密那样的密码的目的被探索，认证，签名等等。在这篇论文，我们简短介绍 DNAcryptography 和 DNA 计算的原则的生物背景，总结 DNA 密码的研究和几个关键问题的进步，讨论 DNA 密码学的趋势，并且比较地位，传统的密码学的有那些的 DNA 密码学和量密码学的安全和申请领域。所有三种密码学在未来互相有他们的自己的优点和劣势和补充，这被指出实际申请。DNA 密码学的当前的主要困难是有效安全理论和简单可实现的方法的缺席。DNA 密码学的研究的主要目标正在探索特征 ofDNA 分子和反应，建立相应理论，发现可能的发展方向，寻找认识到 DNA 密码学的简单方法，并且为未来开发放基础。

英文摘要：

DNA cryptography is a new born cryptographic field emerged with the research of DNA computing, in which DNA is used as information carrier and the modern biological technology is used as implementation tool. The vast parallelism and extraordinary information density inherent in DNA molecules are explored for cryptographic purposes such as encryption, authentication, signature, and so on. In this paper, we briefly introduce the biological background of DNA cryptography and the principle of DNA computing, summarize the progress of DNA cryptographic research and several key problems, discuss the trend of DNA cryptography, and compare the status, security and application fields of DNA cryptography with those of traditional cryptography and quantum cryptography. It is pointed out that all the three kinds of cryptography have their own advantages and disadvantages and complement each other in future practical application. The current main difficulties of DNA cryptography are the absence of effective secure theory and simple realizable method. The main goal of the research of DNA cryptography is exploring characteristics of DNA molecule and reaction, establishing corresponding theories, discovering possible development directions, searching for simple methods of realizing DNA cryptography, and laying the basis for future development.
