An abstract enclave identity is presented. An abstract identity may be a secure identity that may be the same for multiple related, but not identical, enclave instantiations. An enclave identity value may be determined from an abstract enclave identity type with respect to a instantiated enclave. An abstract identity value may be used to determine equivalence of two enclave instantiations that are not identical, such as two similar enclaves hosted on different computers, two enclaves hosted on different native enclave platforms, and two enclaves instantiated from different versions of the same enclave binary images.
