Abstract

Biomolecular cryptography exploiting specific biomolecular interactions for data encryption represents a unique approach for information security. However, constructing protocols based on biomolecular reactions to guarantee confidentiality, integrity and availability (CIA) of information remains a challenge. Here we develop DNA origami cryptography (DOC) that exploits folding of a M13 viral scaffold into nanometer-scale self-assembled braille-like patterns for secure communication, which can create a key with a size of over 700 bits. The intrinsic nanoscale addressability of DNA origami additionally allows for protein binding-based steganography, which further protects message confidentiality in DOC. The integrity of a transmitted message can be ensured by establishing specific linkages between several DNA origamis carrying parts of the message. The versatility of DOC is further demonstrated by transmitting various data formats including text, musical notes and images, supporting its great potential for meeting the rapidly increasing CIA demands of next-generation cryptography.

  • The decryption time for the DNA braille method is 1-2 h, including sample processing, imaging, and readout.

    “The decryption time for this method is 1–2 h, including sample processing, imaging, and readout—this time could be reduced by using high-speed AFM methods and fully automated image analysis algorithms.”
  • Zhang et al. demonstrated in 2019 a "DNA braille" system prepared by patterning biotinylated overhangs onto DNA origami.

    “In the context of DNA data storage, Zhang et al. demonstrated in 2019127 a “DNA braille” system, which was prepared by patterning biotinylated overhangs onto DNA origami.”
  • Fan et al. used AFM to decode information stored in DNA domino arrays.

    “Similarly, Fan et al. used AFM to decode information stored in DNA domino arrays.127”
  • In the DNA braille system, the data are encrypted; only when streptavidin is added and binds to biotin does the pattern become readable by AFM.

    “The data in this system are encrypted; only when streptavidin is added and binds to biotin does the pattern become readable by AFM.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
