abstract:As the ability to synthesize DNA becomes more widespread, it becomes increasingly important to address the resulting risk that dangerous biological agents can be assembled. To address this issue, we would like to be able to screen all DNA synthesis orders against a database of hazardous biological agents. However, we want this system to work without revealing the dangerous sequences we are screening the orders against. Furthermore, the privacy of the DNA synthesis query must also be maintained. Finally, we do not want this screening process to slow down ongoing DNA research. The focus of my project is to advance the development of such a cryptographic screening protocol, achieving all its security goals while maintaining a high level of efficiency.
