Abstract
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. Various enclave operations may be performed with an abstract identity, such as sealing data to an abstract identity, incrementing a monotonic counter, making trusted time measurement.
