Abstract
Technologies for secure inter-enclave communication include a computing device having a processor with secure enclave support. The computing device establishes a first secure enclave and a second secure enclave with the secure enclave support of the processor. The first secure enclave invokes a report instruction to cause the processor to generate a report targeted to the second secure enclave. The report includes a report body and a message authentication code generated using a report key associated with the second secure enclave. The second secure enclave invokes a get key instruction to cause the processor to generate the report key associated with the second secure enclave and generates the message authentication code over the report body using the report key. The first secure enclave and second secure enclave each perform a cryptographic operation on a message using the message authentication code as a cryptographic key. Other embodiments are described and claimed.
