System and method for confidential multi-party software in the loop simulation

A system for securing a software-in-the-loop (SiL) simulation of a real-world system using one or more trusted execution environment (TEEs), comprising:

• a memory;
• and
• a processor operable to:
• assemble one or more unsecured models operable to simulate the real-world system;
• encrypt and generating at least one secured model from the one or more unsecured models using a first cryptographic key;
• decrypt the at least one secured model using a second cryptographic key;
• and
• execute the at least one secured model within the one or more TEEs, wherein the at least one secured model is operable to process incoming data and outgoing data.

A method for securing a software-in-the-loop (SiL) simulation of a real-world system using one or more trusted execution environment (TEEs), comprising:

• assembling one or more unsecured models operable to simulate the real-world system;
• encrypting and generating two or more secured models from the one or more unsecured models using at least a first cryptographic key, wherein the two or more secured models are included within at least one of the one or more TEEs;
• decrypting the two or more secured model using a second cryptographic key;
• and
• executing the two or more secured models, wherein the two or more secured models are operable to process incoming data and outgoing data.
