SESAME's origins lie in the Open Systems Standards work of ECMA, the European Computer Manufacturers Association. In 1987 ECMA started its work on Security in Open Systems. It was here that the early ideas that are the basis of SESAME were formed. Following that first meeting, experts from all of the major computer manufacturers have at different times been involved in this work.
The Common Secure Interoperability (CSI) specification, which is part of the CORBASEC specification, defines the standards for common secure interoperability when using GIOP/IIOP. A part of this standard is the use of defined protocols. CSI-ECMA is one of these protocols.
