Model Protection

Create a protected model for simulation and code generation to share with a third-party

A protected model provides a model reference that conceals underlying implementation details. The model protection process compiles the model and packages the derived artifacts, which support model functionalities without including sensitive IP. See Protect Models to Conceal Contents.

Protect Models to Conceal Contents

Protect a model when you want to share a model with a third party without revealing intellectual property.

Test Protected Models

Test your protected model by comparing it to the original model.

Sign a Protected Model

Attach a digital signature to your protected model.

Package and Share Protected Models

Files to include in the protected model package.

Specify Custom Obfuscators for Protected Models

Specify a post-processing function for files that the protected model creation process generates.

Create Protected Models with Multiple Targets

Create a protected model that supports multiple code generation targets.

Define Callbacks for Protected Models

Customize protected model behavior by defining callbacks.

Best Practices for Creating Protected Models

Choose modeling patterns and protection options to allow the functionalities that you want your protected model to support.
