Explore a groundbreaking biomolecular security solution for DNA data storage in this 19-minute conference presentation. Learn about DNA-Cipher, an innovative approach that addresses the unique security challenges of storing digital data in DNA molecules by requiring biological manipulations for decryption before sequencing. Discover how this solution tackles biological and indexing constraints of DNA strands, including homopolymers and nucleotide sequences used as primers and indexes, while providing resilience against evolving computational threats that compromise traditional digital encryption. Examine the technical implementation involving permutations and rotations of nucleotide blocks across copies of digital DNA sequences, utilizing a numerical cipher for preparing encrypted DNA sequences and a biomolecular DNA-Decipher module for reorganizing nucleotide data blocks. Understand the identification and repurposing of multiple biomolecular operators for security applications, along with a specialized encoding method that simultaneously considers indexing constraints, biological limitations, and the biomolecular decryption process. Review simulation results demonstrating consensus impossibility without biomolecular decryption and explore the biomolecular proof of concept involving 14 distinct operations that successfully outputs decrypted molecules. Gain insights into the biological optimizations required for effective operator application and the feasibility of this novel approach to securing DNA-based data storage systems against current and future threats.
