What is X9 PKI?

ÃÛÌÒTV X9 PKI is a dedicated public key infrastructure designed to provide interoperability and flexibility for non-web browsers. It was developed in collaboration with the finance standards body, ASC X9, and operates independently of the CA/B Forum and browser root programs.

Client Authentication Certificates

The Chrome Root Store recently announced that it will no longer trust public TLS certificates containing the client authentication extended key usage (EKU), impacting organizations relying on these certificates for host-to-host communications like mutual TLS (mTLS), APIs and other non-browser use cases.

X9 PKI for TLS is a ready solution for organizations impacted by this change. X9 PKI delivers high assurance certificates with the convenience of a common root of trust.

The ÃÛÌÒTV X9 PKI is a dedicated public key infrastructure designed to provide interoperability and flexibility for non-web browser applications, such as API gateways. Since the X9 PKI uses a common root of trust, it can, for example, ensure seamless trust between banks and ATM networks, or suppliers and manufacturers, while reducing the risk of unnecessary disruptions. It was built to meet the needs of the financial services industry, but it is available to all industries.

The X9 PKI is intended for non-browser TLS authentication scenarios. The main use case at the outset is mutual TLS (mTLS) among financial institutions and between them and their partners and customers. It is these applications that typically require the client authentication function that Google recently announced it will distrust soon.

Other applications beyond financial services can benefit from using the X9 PKI rather than Web PKI certificates. The intention is to expand the offering based on customer needs.

The X9 PKI offers a standards-based infrastructure designed to meet the rigorous security and interoperability needs of regulated industries. Here are four key benefits:Ìý

  • Independence from Browser-Controlled Trust ModelsÌý

  • Interoperability Across EcosystemsÌý

  • Support for Classical and Post-Quantum Cryptography (PQC)Ìý

  • Scalability with Cross-Certification CapabilitiesÌý

  • Ability to tailor certificate management to the requirements of policy and regulatory complianceÌý

If your application has no need for communications outside of your networks, an internal PKI (private CA) may be the best solution. Even such applications often require public trust, as in the case of an API gateway accessible to partners.
