Technologies for secure inter-enclave communications

A method for secure communication, the method comprising:

• invoking, by a first secure enclave established using secure enclave support of a processor of a computing device, a first processor instruction to cause the processor to generate a report targeted to a second secure enclave, wherein the report includes a report body and a message authentication code, and wherein the message authentication code is generated as a function of the report body and a report key associated with the second secure enclave;
• performing, by the first secure enclave, a cryptographic operation on a message using the message authentication code of the report as a cryptographic key;
• invoking, by the second secure enclave established using the secure enclave support of the processor, a second processor instruction to cause the processor to generate the report key associated with the second secure enclave;
• generating, by the second secure enclave, the message authentication code over the report body using the report key;
• and
• performing, by the second secure enclave, a cryptographic operation on the message using the message authentication code of the report as the cryptographic key.

One or more computer-readable storage media comprising a plurality of instructions that in response to being executed cause a computing device to:

• invoke, by a first secure enclave established using secure enclave support of a processor of the computing device, a first processor instruction to cause the processor to generate a report targeted to a second secure enclave, wherein the report includes a report body and a message authentication code, and wherein the message authentication code is generated as a function of the report body and a report key associated with the second secure enclave;
• perform, by the first secure enclave, a cryptographic operation on a message using the message authentication code of the report as a cryptographic key;
• invoke, by the second secure enclave established using the secure enclave support of the processor, a second processor instruction to cause the processor to generate the report key associated with the second secure enclave;
• generate, by the second secure enclave, the message authentication code over the report body using the report key;
• and
• perform, by the second secure enclave, a cryptographic operation on the message using the message authentication code of the report as the cryptographic key.
