Embodiment Construction

[0034] figure 1 A system is shown for illustrating a first embodiment of the invention, in which the programming of a chip SoC for a mobile radio terminal is protected by a serial number SENR formed according to a secret mapping rule F. The purpose of the programming is to enable the mobile radio terminal equipment manufacturer OEM (Original Equipment Manufacturer) to program a secure operating system into a chip SoC (System on a Chip) manufactured by the chip manufacturer SOCP (SOC Provider). In doing so, it must ensure that only original chips from chipmaker SOCP are provided with an operational secure operating system. The secure operating system includes an authentication key Kauth without which the secure operating system is inoperable. The chip manufacturer SOCP programs the serial number SENR formed according to the secret mapping rule F into the chip SoC, and programs the secret mapping rule F into the security module HSM (High Security Module). The chip manufacturer...

Abstract

The invention provides a method for programming a chip for a mobile end device, wherein, in a preparatory step, a serial number is programmed into the chip and thereafter, in a programming step, the serial number is verified and a programming of at least one further datum into the chip is only carried out if the serial number has been successfully verified. The serial number is verified here by means of a security module (HSM), while employing a secret information item stored in the security module (HSM) and different from the serial number.

Description

technical field [0001] The invention relates to a method for programming a chip of a mobile terminal device, a method for activating a secure operating system while using said programming method, and a method for securely configuring Method for a mobile terminal device containing a chip. Background technique [0002] Mobile terminal devices, such as mobile phones, smartphones, etc., contain a chip (microprocessor chip) with an integrated circuit (IC), also known as SoC (System on Chip), via which controls include, for example, the display screen, Keypads, card readers for SIM cards and / or other components of mobile terminal equipment. [0003] The chip is manufactured by a chip manufacturer (also known as an SoC provider, SoCP), supplied to an end equipment manufacturer (also known as an original equipment manufacturer, OEM) different from the chip manufacturer, and programmed as It has an operating system (that is, the operating system is programmed into the chip), and th...
