Embodiment Construction

[0035] figure 1 A layer representation of the invention is shown. The CA in possession of the two master keys generates a public key IBSp accessible to all components and for each component a private key IBSs generated from the master key taking into account the serial number of the component. Since the private key is generated based on the ATM serial number, the private key is only communicated to the ATM, while the public key is communicated to all components. Here, the CA preferably manages the private key of the ATM, and the ATM manages the private key of the cash box, so that the private key of the cash box is not distributed with the cash box. By this method, it is possible for the CA to perform software updates on the ATM, and for the cash drawer or ATM to identify the legitimacy of the cash drawer or the ATM.

[0036] Now if a cash drawer is inserted into an ATM, the cash drawer can check whether the ATM is an allowed ATM here. In an alternative embodiment, this can...

Abstract

The invention relates to a device and a method for authenticating components of an self-service automatic teller machine, wherein the components comprise unambiguous identification information that can be exchanged among the components, wherein an authentication of the components and / or the information exchanged between the components is carried out by the encryption and / or signature of the information on basis of identity based encryption (IBE) that uses the identification information of the components.

Description

technical field [0001] Method for authenticating components of a self-service automaton (SB-Automat) that possess unambiguous identification information that can be exchanged between components. Background technique [0002] Self-service (SB) robots often have a series of components that must be connected to each other. Typically, these automata have standardized PC platforms that meet special security requirements. Keypads, payment units (banknote separation modules), card readers, monitors and other devices are connected to the PC platform (motherboard) eg via USB interfaces. It must also be noted that inserting a cash drawer in an Automated Teller Machine (ATM) must be authenticated, or that the ATM must authenticate itself to the cash drawer in order for said cash drawer to switch on its capabilities. [0003] In addition, these robots include the possibility of being connected to another computer so that for example a maintenance technician can use his laptop to conne...
