摘要：In the condition of the traditional cryptogram which has been breached successively, this paper mainly studies the current cryptography-DNA cryptogram. Using biology question which has none solution in �if we don�t know the correct primer situations from an unknown mixture of trying to isolate specific DNA of DNA is quite difficult� as the safety of constructing DNA encryption algorithm. Using the chaotic system which is constructed by using Logistic chaos mapping and Henon chaos mapping to produce the pseudo-random to process the plaintext and eliminate the statistical rule. Building the encryption algorithm, and analyzing the DNA encryption algorithm based on PCR technology. And improve the algorithm in the key space, security, and experiment. Doing exclusive or operation between the binary code of plaintext, we can get the new code, and then append the primers. By this way, we can increase the number of primers, and the attackers can never get the plaintext unless he get all DNA chain with information. In addition, it will lead the failure if the target DNA chain is too long when doing the PCR amplification. In this encryption algorithm, the PCR amplification can be successfully by dividing the binary code of plaintext into many short sequences. This paper uses encryption examples to describe the whole encryption algorithm, and then analyses the security and maneuverability of the whole system. And then we get the whole system.
