摘要
The present invention provides secure inter-process communications, and applications thereof. In an embodiment, a shared memory and a message queue are used to provide a secure communication channel between a first computer process and a second computer process. The shared memory provides a path for high-bandwidth data transfer in a forward direction. The message queue provides a path for controlling the data transfer in the forward direction, while limiting data transfer in the reverse direction. A third computer process creates the message queue that is used by the first computer process and the second computer process to control the passage of data. Access to the shared memory and the message queue are enforced using a mandatory access control security policy.
