Our Story

The QX.509 Authenticator is a solution developed as part of the "Mobile Authentication Interoperability for Digital Certificates" (X.509) project, funded by the US Department of Homeland Security Science & Technology Directorate. Its goal is to provide secure authentication for mobile users.

The project aimed to enable the use of highly vetted x.509 certificates on mobile devices for enterprise server authentication using the FIDO protocols. With the QX.509 Authenticator, x.509 Digital Certificates can be used with any FIDO-compliant relying party for authentication, without requiring further development work by the credential issuer nor the relying party.

In simpler terms, the QX.509 Authenticator provides a high level of identity assurance and strong token assurance through the use of FIDO protocols, while also meeting various government standards such as FIPS 140-2, NIST 800-63-3, NIST 800-157, and NIST 800-57.

This effort, a part of the "  The Mobile Authentication Interoperability for Digital Certificates (MAIDC) " project, has been funded in part by the United States Department of Homeland Security's Science and Technology Directorate under contract # D15PC00001.
