Let’s take a look at what the X9 PKI<\/a> is, how it’s been built, and how it will be used.<\/p>\n\n\n\n Let\u2019s hash it out.<\/span><\/p>\n\n\n<\/span><\/span>\n\n\n X9 Financial PKI<\/strong><\/a> is a public key infrastructure<\/a> that\u2019s designed specifically to meet the needs of financial institutions, merchants, securities companies, third-party payment service providers, and many other financial services organizations. It provides resilient, stable, and secure security infrastructure and certificate lifecycle management capabilities.<\/p>\n\n\n\n Let\u2019s take a quick look at the PKI architectural model of the X9 Financial PKI, of which there will initially be a single root CA and two issuing CAs chaining back to it (although this will likely expand over time.):<\/p>\n\n\n\n We\u2019ll speak more about the ASC X9 governing body in just a few moments. But the main takeaway here is that X9\u2019s Financial PKI shifts the dynamic of PKI as we\u2019ve traditionally known it, creating a dedicated security framework that puts financial institutions firmly in the driver\u2019s seat. Putting it another way, X9 PKI addresses the needs of this distinct community, which are different than those of the Web PKI.<\/p>\n\n\n\n Click on the banner below to visit DigiCert’s X9 PKI webinar event registration page<\/a>:<\/p>\n\n\n\n <\/p>\n\n\n\n Here\u2019s a quick reminder of what traditional PKI architecture<\/a> looks like, which consists of many root CAs and even more subordinate and issuing CAs that chain back to them:<\/p>\n\n\n\n The X9 Financial PKI is similar to the traditional browser-oriented public key infrastructure in that it uses public key cryptography and a certification authority (CA) issues trusted digital certificates to organizations that are responsible for managing them securely.<\/p>\n\n\n\n However, the similarities end there. This is because the X9 PKI framework is specific to the sector\u2019s unique needs to ensure interoperability and improve data security against modern and future threats (i.e., Quantum Computing<\/a>). It\u2019s likely to offer a bit more flexibility to meet the sector\u2019s broad range of use cases.<\/p>\n\n\n\n Knowing this, there are some key differences between X9 Financial PKI and the traditional PKI ecosystem used by organizations globally:<\/p>\n\n\n\n The Accredited Standards Committee X9 Inc.<\/strong> (ASC X9<\/strong>)<\/a> is a non-profit organization that develops and maintains national and international standards for the financial services sector. X9 members<\/a> include:<\/p>\n\n\n\n ASC X9F<\/strong> (also known as the Data and Information Security Subcommittee) is the subgroup that\u2019s charged with creating the independent X9 Financial PKI framework to meet the unique needs of the U.S. Financial Services industry. ASC X9\u2019s PKI Study Group<\/a> has:<\/p>\n\n\n\n Examples of some specific use cases include:<\/p>\n\n\n\n Ultimately, the goal of X9 PKI is to provide organizations with the tools, skills, and knowledge to overcome PKI complexities and address the industry\u2019s ever-evolving cybersecurity threats and concerns.<\/p>\n\n\n\n This project involves expanding modern public key infrastructure in a way that works specifically for the Financial Services industry without external interference. But what are the advantages of creating a unique and separate private PKI for this specific industry?<\/p>\n\n\n\n The financial sector is no stranger to data privacy and security-related changes:<\/p>\n\n\n\n The development of X9 Financial PKI isn\u2019t something that\u2019s happened overnight. It\u2019s something that has been in the works for the better part of a decade:<\/p>\n\n\n\n Something to note is that this year (2025) is when X9 study group members will begin to see the fruits of their labor. For example (the following dates are estimates):<\/p>\n\n\n\n The need for X9 PKI boils down to different needs and use cases of the Financial Services industry. For example, the ways that POS systems connect to credit card companies and ATM machines connect to banks are very different from a human using a browser to visit websites. <\/p>\n\n\n\n If your organization needs to secure data in transit for a payment system, then the X9 PKI may be a better fit for your needs than traditional SSL\/TLS certificates<\/a> from a browser-trusted CA. Reach out to our PKI team<\/a> and we\u2019ll help you determine if X9\u2019s PKI will meet your needs. <\/p>\n","protected":false},"excerpt":{"rendered":" After about eight years of planning and development, the Accredited Standards Committee X9 Inc.
