英文摘要：

In recent years, cryptography has been a hot topic in the field of information secure. Due to immense information storage density, ultra-low power consumption and hugely parallel processing speed of DNA molecule, DNA molecular computational capability has attracted widespread attentions. DNA molecular computing is related to biology, computer science, and math. There are many research areas about DNA molecular computing. Especially in the aspect of cryptography study, breaking traditional cryptosystems with DNA molecular computing, combining the new technologies with the traditional ones to build more reliable cryptosystems bring challenges and chances to the existing cryptosystems. This paper depicts how to construct the DNA computing models which are used to break the traditional cryptosystems of DES, RSA and NTRU, proposes the new model of encryption and decryption with the cryptography principle such as the one-time pad encryption. In addition, the drawbacks and perspective of DNA cryptography are also proposed in this paper.
