- The New XML Standards for Secure Web Services
- Until recently, Web services security was based on Public-Key Infrastructure PKI at the transport level. Most Web services developers with security concerns rely on SSL/TLS (Secure Sockets Layer/Transport Layer Security) encryption, the industry-accepted standard protocol for secured encrypted communications over TCP/IP. But SSL doesn't work that well for Web services....
