Abstract

The invention relates to methods and systems for securely transferring embedded code or data to a customer, in particular to methods and systems for securely transferring embedded code, data files or program files designed for a device to a customer in order to prevent the embedded code, data files or program files from being used on unauthorized devices.

Description

technical field [0001] The present invention relates to methods and systems for the secure transfer of embedded code and / or data to customers, in particular for the secure transfer of embedded code, data files and / or program files designed for devices to prevent embedded code, Method and system for data file and / or program file use on unauthorized devices. Background technique [0002] Manufacturers of various devices, such as semiconductor manufacturers, for example, sell their devices, such as integrated circuit components, to eg different customers. A dedicated supplier provides embedded code or data for the corresponding device to configure and / or customize the corresponding device according to the customer's requirements and needs. The customer can then program the device purchased from the manufacturer at its location with embedded code or data obtained from the supplier. [0003] Such transmission of embedded code or data involves several piracy risks. Embedded cod...
