Disclosed are nucleic acid based encryption technique and the corresponding decryption method. The encryption method comprises the steps of dividing an original nucleic acid sequence corresponding to a predefined message according to a predetermined cipher table into a plurality of fragmented nucleic acid sequences, ligating the fragmented nucleotide sequences with oligomers for sequence analysis and oligomers for sequence recognition. The corresponding decryption method comprises the steps of using the corresponding PCR primers and sequencing primers to determine the sequence information of the fragmented nucleotide sequences, combining with the information provided by oligomers for order arrangement to decode the original nucleotide sequence. This multiple encryption method can provide more security to a predefined message desired to keep confidential.
