What we offer

Research

We investigate new forms of compliance, confidentiality, compression, integrity, and credibility of digital data and computations by exploring zero-knowledge proof technology via our research papers.

Development

We develop protocols and solutions for data security, privacy, and control (e.g. ianzn identity). We publicly expose proofs of concepts and tooling to improve the integration and maintenance of novel cryptographic concepts.

Education

We educate security and privacy concepts of research papers and tooling via extended blog articles written in less-technical jargon. Our educative resources rely on step-by-step walkthroughs and enable cross-platform reproduction.

Consulting

Based on your problem definition and software stack, we assess if and how cryptographic technologies solve your compliance and provenance requirements. If our work catches your interest, please contact us.

Journey

Where do we come from

We went through the studies of computer engineering and security at a German university, completing our education with a PhD degree.

Our journey started with the investigation of modern online identity solutions, which led us to interesting collaborations with renowned american universities and professors. We create, collect and share educating material, development, and research of state-of-the-art computer security and engineering. We identify leading reasearch, relevant people, and beneficial programs and discuss recent topics and trends such that more people can acquire necessary expertise. With that, we hope to motivate young people to pursue PhD programs in challenging domains such as incrementally verifiable computation and privacy or to take on jobs that enhance the security and privacy of our Internet.
