With a vision emerging for dynamically composable and interoperable medical devices and information systems, many communication standards have been proposed, and more are in development. However, few include sufficiently comprehensive or flexible security mechanisms to meet current and future safety needs. In this paper, the authors enumerate security requirements for the communication stack of a medical composition framework. They then survey existing medical and non-medical communication standards and find significant gaps between required properties and those that can be fulfilled even by combinations of currently standardized protocols.
