【摘要】 针对现有的DNA加密算法中并未涉及DNA化学反应的这一弊端，提出了一种将Henon混沌映射和DNA链置换反应相结合的信息加密方案。首先利用Henon映射经过置乱和异或操作后获得的新序列对明文信息进行异或操作，随后转换成DNA序列；其次对DNA序列进行DNA链置换反应，得到新的DNA序列；最后对新的DNA序列进行解码，得到加密文本。实际分析表明，该加密方案具有较好的加密效果和安全性。更多还原

【Abstract】 Aiming at the disadvantage that the existing DNA encryption algorithm does not involve the chemical reaction of DNA, a text information encryption scheme that combines Henon chaotic mapping and DNA strand replacement reaction is proposed. The scheme first performs XOR operation on the plaintext information using the new sequence obtained after scrambling and XOR operation by Henon mapping, and then converts it into DNA sequennce. Secondly, the DNA sequence is decoded to obtain the encrypted text. The case anlysis shows that the encryption scheme has better encryption effect and secrity.更多还原
