Chaos Communication Chemistry: DNA security systems based on molecular randomness

**Over the past few decades, nucleic acids have increasingly been investigated as alternative data storage media and platforms for molecular computing. This talk builds on past research and introduces another branch to the field: DNA cryptography based on random chemistry. This technology provides a platform for conceiving new security architectures that bridge the physical with the digital world.** Nucleic acids have been theorized as potential data storage and computation platforms since the mid-20th century. In the meantime, notable advances have been made in implementing such systems, combining academic research with industry efforts. After providing a general introduction to the interdisciplinary field of DNA information technology, in the second half of the talk focuses on DNA-based cryptography and security systems, in particular zooming in on the example of chemical unclonable functions (CUFs) based on randomly generated, synthetic DNA sequences.
