US Patent 11343082 Resource sharing for trusted execution environments

The technology disclosed herein enables resource sharing for trusted execution environments. An example method can include: establishing a first trusted execution environment (TEE) in a first computing device; establishing, by the first TEE, a set of shell TEEs, where each shell TEE is configured in view of one or more configuration parameters associated with the set of shell TEEs; receiving, by the first TEE, a request from a tenant computing device to establish a second TEE; determining, by the first TEE, whether the configuration parameters associated with the set of shell TEEs satisfy one or more request parameters for the second TEE; and responsive to determining that the configuration parameters associated with the set of shell TEEs satisfy the one or more request parameters for the second TEE, establishing, by the first TEE, the second TEE to satisfy the request, wherein the second TEE is selected from the set of shell TEEs, and causing, by the first TEE, the second TEE to communicate with tenant computing device.
