Embodiment Construction

[0027] FIG. 1 shows a schematic view of a first embodiment of a system with a security module 1 formed according to the invention. The security module 1 is formed as a component of an electronic device 2 , such as a personal computer, a personal digital assistant (PDA) or a mobile phone, and has a security unit 3 , a device interface 4 and a passive contactless interface 5 . The security unit 3 provides various security functions such as storing data for secure access, performing cryptographic operations according to Trusted Computing Group (TGC) specifications, etc., so that the security module 1 can be used as a trusted platform module (TPM). Thus, with the security module 1 in the electronic device 2 (which alone is not secure), a certain security standard can be achieved.

[0028] Each of the device interface 4 and the passive contactless interface 5 is connected to the security unit 3 . Via the device interface 4 there is a communication connection to the software 6 of t...

Abstract

The invention relates to a system comprising a first electronic device (2), a security module (1) and a second electronic device (9, 10, 14, 21). The security module (1) is firmly connected to the first electronic device (2), and includes a security unit (3) for safely storing data and / or for performing encryption operations and for communicating with the first electronic device (2) A first interface (4) for communication. The system of the invention is characterized in that the security module (1) comprises a second interface enabling direct wireless communication with the second electronic device (9, 10, 14, 21).

Description

technical field [0001] The present invention relates to a system having a plurality of electronic devices and a security module securely bound to one of the electronic devices. Furthermore, the invention relates to an electronic device having a security module firmly bound to the electronic device. Background technique [0002] It is known to provide a computer system with a security module formed as a security chip firmly bound to the computer system. When such a security module complies with the specifications of the Trusted Computing Group (TGC), it is also called a Trusted Platform Module (abbreviated as TPM). These specifications allow for defined security standards. [0003] With the help of a security module, a computer system can be identified as trustworthy and can be protected against manipulation. This is particularly beneficial when utilizing such a computer system to perform security-related operations. [0004] The security module can be accessed by the ope...
