摘要: 为减少DNA加密算法中的生物操作,提出一种基于DNA序列运算的信息隐藏方案.该方案将海量DNA序列作为天然的DNA密码本,结合DNA数字编码规则,将待加密的信息与参考序列进行异或运算后转换为DNA序列,再通过混入冗余序列来实现信息的隐藏.对该方案性能和安全性的分析与验证结果表明,该方案不需要生物操作,成本低,易于传输,有较强的安全性.Abstract: In order to reduce the biological operation of mass DNA cryptography algorithm, an information hiding sequence was proposed based on DNA sequence operation. Using DNA sequence database as a natural DNA password, combining with the DNA digital encoding rules, the information to be encrypted and reference sequences was converted to DNA sequence by an XOR operation.Then, by mixing with redundant sequences information hiding was achieved. The performance and security analysis of the scheme results showed that the sequence did not need the biological operation, had the character of low cost,was easy to transport and had strong security.
