TECHNIQUES FOR ENCLAVE CONFIDENTIALITY MANAGEMENT

Various embodiments are generally directed to techniques for enclave confidentiality management, such as for protecting cross enclave confidentiality on servers, for instance. Some embodiments are particularly directed to a computing platform including hardware and/or instruction set architecture (ISA) extensions that ensure enclaves cannot access confidential data of other enclaves. For example, key programming ISA extensions and/or hardware changes to the page miss handler (PMH) may ensure that the key uniquely associated with an enclave is used for its memory accesses.
