Abstract
The present disclosure describes secured interprocess communication (IPC). The operating system traps application-level IPC calls to an IPC agent, which handles the IPC call. The IPC agent executes in a trusted execution environment so that communications between the applications involved in the IPC are secure. Since processing of IPC by the IPC agent bypasses the operating system, IPC remains secure despite any attacks against the operating system code.
