In a number of OpenStack projects, systems communicate via a messaging/RPC mechanism. The safety and reliability of this mechanism is vital to the security of OpenStack clouds. However, this messaging layer currently relies on implicit trust based on basic network connectivity. In Grizzly, there exists a blueprint to add cryptrographic trust between systems.
Eric Windisch is currently developing this trust mechanism based on feedback from the Folsom design summit. He will highlight the requirements of a trusted messaging system and the architecture of this solution.
