| 摘 要： | DNA密码是伴随着DNA计算的研究而出现的密码学新领域。利用DNA合成技术、PCR扩增技术以及DNA数字编码技术,结合传统密码学提出了一种基于DNA技术的加密方案。方案利用引物对于PCR扩增技术的特殊作用,提出要以引物和编码方式为密钥,采用传统的加密方法对明文进行加密预处理,可有效防止可能词作为PCR引物进行攻击。生物学困难问题和密码学计算困难问题为该方案提供了双重的安全保障,安全性分析表明该加密方案具有很强的保密强度。

| Abstract: | DNA cryptography is a new born cryptographic field emerged with the research of DNA computing.In this paper,an encryption scheme is designed by using the technologies of DNA synthesis,PCR amplification and DNA digital coding as well as the theory of traditional cryptography.By applying the special function of primers to PCR amplification,the primers and coding mode are used as the key of the scheme.The traditional encryption method and DNA digital coding are used to preprocess the plaintext,which can effect... |
