WS-SecureConversation (Web Services Secure Conversation Language)
WS-SecureConversation, also called Web Services Secure Conversation Language, is a specification
that provides secure communication between Web services
using session
keys. WS-SecureConversation, released in 2005, is an extension of WS-Security and
WS-Trust.
WS-SecureConversation works by defining and implementing an encryption key to be shared
among all the entities involved in a communications session. The originating entity defines the
encryption algorithm and
generates the key, which is embedded in a SOAP (Simple
Object Access Protocol) message. (This key can also be used to encrypt the SOAP message itself.)
When the intended destination entities receive the message, they decrypt it and retrieve the
session key, which can then be used to facilitate secure communications for the remainder of that
session.
WS-SecureConversation is a part of the Microsoft Web Services Enhancement 2.0 toolkit.

Papows describes how faulty software caused a huge charge to debit card holder's account and why such mistakes are on the rise in this interview. Papows notes the three most pressing drivers for software glitches: loss of intellectual knowledge, market consolidation and the ubiquity of technology
