  • Methodologies to secure inter-process communication based on trust
    Patent number: 7774599
    Abstract: A system securing inter-process communication (IPC) based on trust includes a user quota mechanism to provide resource management of IPC's. A single user is allowed to allocate a fixed amount of objects less than a system maximum. A trusted IPC mechanism mediates access to IPC objects by employing signed executables signed by a key and containing a list of trusted keys. A trust relationship is used among a set of subjects connected to an IPC to determine whether communication can be carried out between processes. In order for the processes to communicate via an IPC, either they have to trust each other, or a kernel must trust one process and that process must also trust the other process.
