Abstract

Abstract: Based on the form of a one-time-pad, we proposed the information encryption and decryption with DNAzyme cutting in this study. To encrypt the information ,we xor the key with the plaintext and we can get the cipher text. Then the plaintext , the key and the ciphertext are compiled into DNA codes. In accordance with the rule , the recognition sites of some DNAzyme combine with the cipher text and the key into the entire DNA sequence. Thus, the DNAzyme here has high specificity, even the data pool is intercepted , it is too hard to decode the ciphertext without the right DNAzyme. Compared with the traditional encryption technology, DNA encryption has many potential advantages, such as huge storage capacity, difficulty of passwords deciphering and high specificity. Thus, this study may demonstrate that DNA encryption has great potential applications in the field of information security.
