Niobium and Silicon Highway Technologies collaborate to develop the world’s fastest complete Fully Homomorphic Encryption (FHE) accelerator

Volos, Greece and Dayton, Ohio, US – March 15th, 2024:

Niobium Microsystems, a leading provider of Zero Trust Computing solutions and Silicon Highway Technologies (SiHi), a Physical Design Services start-up, are excited to reveal their collaboration to develop the industry’s first Full-Homomorphic Encryption (FHE) accelerator. This dedicated FHE System-on-Chip (SoC) opens the door to a multitude of innovative applications, unlocking the intrinsic value of data while maintaining its privacy. It also paves the way for new applications across various industries, including finance, healthcare, logistics, and beyond..

SiHi engineers collaborated closely with the Niobium team to tackle hardware physical design challenges in the accelerator project. Through this partnership, various obstacles in chip design and implementation were overcome successfully. Additionally, SiHi employed its Asynchronous Timing Analysis EDA tool, known as “ASTA,” to assess and analyze the cyclic circuit components of FHE. ASTA facilitated the analysis of large mixed synchronous and asynchronous circuits, thereby reducing the traditional design cycle time for cyclic circuits.


Kevin Yoder, Niobium’s President & CEO, noted:” The SiHi team proved to be an invaluable partner in our project. Their experts showcased a remarkable level of professionalism and commitment throughout the collaboration, that proved critical for us achieving our technical and business goals.”

Christos Sotiriou, SiHi’s General Partner noted: “Niobium is a pioneer in innovative FHE technologies, that can enable a host of different applications that require data to be processed in a private and secure way. We were honored to have contributed to such an innovative and challenging project and deliver quality results on time and on budget. This is a significant testimony to the EDA and Design Services capabilities of a growing company”
