摘要
针对现有的基于DNA序列进行信息加密算法中没有涉及到DNA计算中化学反应这一问题,提出了基于聚合酶链置换反应的2D-LASM混沌映射文本加密算法.该算法将混沌映射产生的伪随机序列和明文信息进行异或操作,然后转换成DNA序列;随后再将DNA序列进行聚合酶链置换反应得到新的DNA序列.对新的DNA序列进行解码,得到密文.最后对该算法的密钥空间进行分析,可知该算法具有较好的加密效果.
Aiming at the problem that the existing information encryption algorithm based on DNA sequence does not involve chemical reactions in DNA computing,a 2D-LASM chaotic map text encryption algorithm based on polymerase chain reaction permutations was proposed.This algorithm performs an XOR operation on the pseudo-random sequences generated by chaotic mapping and the plaintext information,and then converts them into DNA sequences.Subsequently,DNA sequences were subjected to polymerase strand displacement reactions to obtain new DNA sequences.Decoding the new DNA sequences then generates the ciphertext.Finally,the key space of the algorithm was analyzed,which shows that the algorithm has a good encryption effect.
