Digital certificates move to interoperability

Public key infrastructure (PKI) and digital certificates promise to bring security and identity trust to the world of e-commerce. Extensible Markup Language (XML) promises to make it easier than ever to share data across applications. Bringing the two closer together would obviously be of great benefit to the online economy and this is what VeriSign, Microsoft and webMethods had in mind when they collaborated on the XKMS (XML Key Management Specification) framework last year.
