Abstract

A method for implementing a software update for a selected enclave of a computing system includes obtaining, by a security monitor (SM) of the computing system, the software update for the selected enclave, installing, by the SM, the software update for the selected enclave to provide updated enclave software code, and measuring, by the SM, the updated enclave software code to provide a software update measurement. The updated enclave software code is stored in a memory region isolated from a memory region in which data for the selected enclave is stored. The method further includes transmitting, by the SM, the software update measurement to one or more respective other enclaves that share a memory region with the selected enclave.
