A Software in the Loop (SiL) system and method is disclosed which may include a simulator operable to provide an environment to simulate dynamic systems, enable rapid development, validation of systems, and testing of complex systems. The system and method may include assembling one or more unsecured models operable to simulate the real-world system. The system and method may then encrypt and generate at least one secured model from the one or more unsecured models using a first cryptographic key. The at least one secured model may be decrypted using a sealed decryption key. The decrypted secured model may then be executed within the one or more TEEs. The at least one secured model may be operable to process incoming data and outgoing data.

A secure programming system and method for provisioning and programming a target payload into a programmable device mounted in a programmer. The programmable device can be authenticated before programming to verify the device is a valid device produced by a silicon vendor. The authentication process can include a challenge-response validation. The target payload can be programmed into the programmable device and linked with an authorized manufacturer. The programmable device can be verified after programming the target payload by verifying the silicon vendor and the authorized manufacturer. The secure programming system can provision different content into different programmable devices simultaneously to create multiple final device types in a single pass.

A wireless earpiece for digital rights management is provided. The wireless earpiece includes a processor disposed within the ear piece housing, a speaker operatively connected to the processor, a storage medium disposed within the ear piece housing and operatively connected to the processor, and a wireless transceiver disposed within the ear piece housing and operatively connected to the processor. The processor may be configured to access audio files stored on the storage medium to play the audio files over the speaker. The processor may be configured to provide a digital rights management feature for one or more of the audio files. The processor may be further configured to access an audio stream conveyed to the earpiece through the wireless transceiver. The processor may be further configured to provide a digital rights management for the audio stream.

The apparatus disclosed herein, in various aspects, includes a digital asset, and an amulet that comprises an encrypted self-validating string. The amulet may be external to the digital asset. The apparatus may include a manager that cooperates securely with the digital asset and cooperates securely with the amulet to control access to the digital asset as specified by the amulet. In some aspects, the manager cooperates with the digital asset and with the amulet, at least in part, through shared memory in process space. In other aspects, the manager cooperates with the digital asset and with the amulet, at least in part, through a RAM drive in memory, the RAM drive at least partially hidden from an operating system of the computer. In yet other aspects, the manager cooperates with the digital asset and with the amulet, at least in part, through a virtual machine accessible only by said apparatus. The amulet, the manager, and the digital asset are either operably receivable by a computer or are operably received by the computer, in various aspects. Related methods and compositions of matter are also disclosed.

The invention is a method for managing an instance of a class in a secure element embedded in a hosting machine and including a Central Processing Unit, a storage area and a virtual machine. The method comprises a step of receiving by the secure element a load file containing a binary representation of a package of the class and a step of instantiating the instance from the package and storing the instance in the storage area. The load file includes a specific component which is a custom component within the meaning of Java Card™ specifications and which contains executable data. The instance requests the execution of a subset of the executable data by directly invoking the subset of executable data through an Application Programming Interface.

A computer system is configured for digital rights management for distributing and tracking downloadable proprietary source code defining a 3-D object and being usable to print the object on a 3D printer and protect the 3D object data from unauthorized printing. The computer system stores an inventory of proprietary source code corresponding to designs of a plurality of 3D objects, and enables a user to see the inventory of designs of the plurality of 3D objects in an online store, and permits the user to securely purchase use of the source code of a desired 3D object viewed therein. The computer system sends the proprietary source code defining the desired 3D object to a 3D printer, and controls printing of the desired 3D object made by the 3D printer to prevent further use of the source code when the purchased use in completed, using one of three different typologies.
