Embodiment Construction

[0035] figure 1 shows in general terms a block diagram of a circuit, in particular an integrated circuit 1, with hardware and / or software for identifying and / or authorizing a device and a first unit E1 and a second unit for identifying and / or authorizing a data carrier E2 exchange data directly with each other.

[0036] like figure 1 Schematically shown, the first unit E1 is essentially formed by a commissioned platform module TPM with a central processing unit 2, which cooperates with a ROM 3, a RAM 4 and a non-volatile memory 5 which may be formed, for example, by EEPROM or flash memory . There is also an encryption machine 6 provided to the first unit E1 (TPM), and connected to figure 1 The interface 7 of the central processing unit 8 of the device 23 , which is not shown in detail, can be, for example, a low pin count interface, or LPC for short.

[0037] The first unit E1 constituted by the entrusted platform module TPM serves to authenticate and / or identify and / or au...

Abstract

In a method of and circuit for identifying and / or verifying the hardware and / or software of an appliance and of a data carrier, for example a smartcard, cooperating with the appliance, it is provided that a first unit (E1) for verifying the hardware and / or software of the appliance, in particular a Trusted Platform Module (TPM), and a second unit (E2) for verifying and / or identifying and authorizing the external data carrier, in particular a Secure Application Module (SAM), are coupled for direct data exchange via a communication interface (17) of the central arithmetic units (2, 10), in order to reduce or eliminate the possibility of attack or manipulation.

Description

technical field [0001] The invention relates to a method for identifying and / or authenticating hardware and / or software in a device and in a data carrier cooperating with the device. [0002] The invention also relates to a circuit for identifying and / or authenticating hardware and / or software in a device and in a data carrier cooperating with the device. [0003] The invention also relates to a device comprising such a circuit. Background technique [0004] For identifying and / or authenticating hardware and / or software in a device or a data carrier cooperating with a device, protecting electronic data stored on the device or on a data carrier or that can be communicated between a data carrier and a device against unauthorized access Access becomes increasingly important. [0005] Such data may be stored or used eg in a PC, CD player, DVD player, TV, mobile phone or PDA, where these devices contain hardware and / or software that must be protected from unauthorized access. ...
