As digitization continues, connected devices are making their way into more and more areas of everyday life. However, these are often vulnerable to cyberattacks; in the past, many end consumers, such as users of online services, were affected in addition to industry and businesses. A German consortium of industry, university and research institutes aims to make these systems more secure in the future thanks to light-based data transmission and computation. Over the next three years, the "Silhouette" project (Silicon Photonics for Trusted Electronic Systems) will develop universally applicable solutions. The German Federal Ministry for Education and Research BMBF is funding the project with around 12 million euros.
