Embodiment Construction

[0026] figure 1 A block diagram of a security module 100 is shown, which has connections 101 , 102 for the connection interface 8 and battery connections 103 and 104 for the battery interface of the battery 134 . While the security module is primed with the cured potting substance, the battery 134 of the security module 100 is replaceably mounted outside the potting substance on the circuit board. The circuit board carries battery connection terminals 103 and 104 for connecting electrodes of a battery 134 . The security module 100 is plugged into a corresponding interface 8 of a main board (motherboard) 9 by means of connectors 101 , 102 . A first connection 101 establishes a communication connection with the system bus of the control device, a second connection 102 is used for supplying the safety module 100 with system voltage. Via pins p3 , p5 - p19 of connector 101 are address and data lines 117 , 118 and control line 115 . The first connector 101 and / or the second conn...

Abstract

A method for protecting a security module includes the steps of monitoring proper insertion of the module on a device motherboard with first, second and third function units, erasing sensitive data due to an improper use or a replacement of the module with the second function unit, inhibiting the functionality of the module with the third function unit during a replacement of the security module, re-initializing the previously erased, sensitive data following proper use or replacement of the security module, and re-commissioning by enabling the function units of the security module.

Description

technical field [0001] The invention relates to a method of protecting a security module, and a security module. Such a postal security module is especially suitable for postmarking machines and postal processing machines or computers with postal processing functions. Background technique [0002] Modern frankers such as the heat transfer franker disclosed in US 4746234 use an all digital printing unit. In principle, any text and special symbols can thus be printed in the postmark printing area as well as any or payment-related advertising content. For example the Postmarker T1000 has a microprocessor housed in a secure housing with a slot for feeding letters. A mechanical letter sensor (micro switch) gives a print request signal to the microprocessor when a letter is fed. Postmark prints include pre-entered and stored postal information for letter delivery. The control unit of the stamping machine completes the settlement according to the software, monitors the real-tim...
