Abstract: Disclosed herein are approaches to isolate the execution of an embedded programming language virtual machine (VM) in a multi-tenant database management system (DBMS). At least a portion of a shared memory area may be associated with a memory protection key. A VM embedded in a database process of a DBMS may initiate execution of a user program. Execution of the database process may transition to a privileged mode, which may enable access to the at least a portion of the shared memory area by the VM. The VM may access the at least a portion of the shared memory area. Execution of the database process may transition to an unprivileged mode and disable access to the shared memory area by the VM. Further, a signal handler may receive a signal from a DBMS, wherein the signal interrupts a VM executing a user program in a database process, and the signal handler executes in the database process.

Abstract: Methods, systems, and devices for providing for trust in a distributed environment are disclosed. In a distributed environment, various devices may be remote to one another and may interact with one another via one or more operable connections. Through the operable connections, various communications may be exchanged. However, the operable connections may not natively support authentication of any particular device in the distributed system. Consequently, entities in the distributed system may not intrinsically trust that the communications received through the distributed environment are authentic. The entities of the system may mutually authenticate one another prior to trusting communications from the other entities. For example, in a scenario where a client wishes to access data hosted by a data source, the client and data source may go through a process of mutually authenticating one another. By doing so, a trusted environment may be established.
