本文介绍了DNA密码学产生的背景，并简要介绍了DNA分子的特点、关键生物技术和相关软件。然后研究了DNA加密设计中的关键和基础部分--生物学难题，提出了我们自己的难题--重叠部分被破坏后的组装困难，并通过实例证明了其困难性。在分析了DNA编码和对称加密机制的基础上，利用DNA数字编码和DNA片段拼接技术，设计了一个对称加密系统。安全性分析证明该方案具有较高的保密强度。
In this paper, the authors introduce the background of DNA cryptography, and briefly describe the features of DNA molecular, key bio-technologies and related software. And then the authors study the difficult biological problem which is the key and basic part in designing of DNA encryption, and put forward our own difficult problem which is that it is difficult to assembly when overlaps are destroyed and prove its difficulty with examples. After analysis of encoding of DNA and mechanism of symmetric encryption, the authors design a symmetric system using the technology of DNA digital coding and DNA fragment assembly. The security analysis proves that the scheme has high confidential strength.
