STORK 2 started in April 2012. It does not seem to address the improvement of interoperability with industry standards nor to facilitate the standardization with an SDO[3]. STORK 2 puts emphasis on expanding use cases from G2C to G2B and B2C types.

Interoperability between both protocols is highly desirable. A rich ecosystem of products, libraries, supporting tools and extensions exists that STORK deployments could tap into if technical interoperability would be improved. On the other hand, existing federations based on mature enterprise or open source products could benefit from STORK, as it proposes a government-backed and low-cost solution with high-assurance credentials.


  1. A summary of differences is available at the Kantara eGov Working Group wiki
  2. It might be attributed to the fact that STORK was driven more by legal than technical challenges.
  3. SDO: Standards Development Organization like ISO, CEN, OASIS, ETSI and others.
