DNA Vernam cipher

This encryption method is based on a truly random key used only once in logical XOR operation with the plaintext. Binary XOR was performed using biomolecular computation and artificially designed DNA motifs. A study of most suitable DNA structures was performed and the isomer of double crossover molecule (DX) named DAE molecule was chosen as a building block of mathematical XOR operation. These structures named also DNA tiles can perform self-assembling operations. Another important property of these structures is the natural hybridization process between them which gives a truly random symmetric key.
