摘要:
In a security module and a method for protecting a security module, wherein security-relevant data are stored in a memory in the module, proper insertion of the security module on a device motherboard is monitored with a first function unit and a second function in the security module. The first function unit signals the status of the security module. The second function unit detects improper use or improper replacement of the security module, and upon detection of improper use or improper replacement, the second function unit causes the security-relevant data to be erased.
摘要:
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. An arrangement implementation of the method has an unplugged status detection unit that has a circuit for resettable self-holding of a status indicator, the self-holding being triggered when the voltage level on a test voltage line deviates from a predetermined potential. A processor connected to the other function units and is programmed to identify and modify the status of the security module.

A security module with status signaling, has a battery, and function units that are interconnected with one another and are covered by a casting compound. The battery is replaceably arranged on the security module, with the casting compound surrounding a first part of the printed circuit board, and a second part of the printed circuit board for the replaceably arranged battery being free of casting compound. For signaling the module status, an optical or acoustic signal element is connected to the printed circuit board.

In an arrangement for a security module that is plugged via an interface onto a base plate of a postal device, particularly a postage meter machine, the battery is replaceably arranged on the security module, and the voltage monitoring unit includes a circuit for a resettable self-holding, the self-holding being triggered when the battery voltage drops below a predetermined threshold. The status can be interrogated by a processor. The resetting of the self-holding can only be triggered when the battery voltage has risen above the predetermined threshold.

In an arrangement for the power supply for a security domain of a device, a first battery is connected to a first input of a battery switchover device in the security region and a second battery is arranged in a non-security region of the device housing and is connected to a second input of the battery switchover device. The battery switchover device is coupled to a monitoring unit in the security region of the device. The monitoring unit is preferably composed of an analog-to-digital converter and a module processor for the evaluation of the connected battery voltages.

In a method and arrangement for determining a requirement to replace a component in a device, the measurement of a first parameter that has an unbeneficial influence on the consumption or the service life of the component is replaced by the measurement of at least two parameters that represent the first parameter and whose changes allow the current condition of the component to be calculated. A count reading is thereby modified such that it approaches an outage threshold that is specific for the component and such that the device emits a warning before the end of use or end of the service life of the component part is reached. The invention can be advantageously utilized for the indirect measurement of parameters of components that are located in a security module or in its immediate proximity, for example for determining a requirement for battery replacement for security modules.

An arrangement for providing data in the context of security management for a franking system has a remote data center at which a list of data sets is stored the data sets containing security information as well as information regarding associated security policies, appertaining at least to security measures and the location of their storage in the franking system. A method for server-controlled security management of performable services in an electronic system includes the steps of receiving a request for a desired service, determining a security feature to be selected and generating a data set corresponding thereto, selecting a logical channel and transferring to data set via that channel establishing the service end, and waiting for receipt of a further service request or for the ending of the communication connection.

In a method and thermotransfer printing device for setting the speed of a relative movement between the print head and a recording medium during a printing procedure in the thermotransfer printing device, in particular for setting the transport speed of a mail piece in a thermotransfer printing franking machine, the heat energies required for the generation of a predeterminable print image are calculated for the individual heating elements of the print head from start value that has been established for the desired speed. It is subsequently computationally checked whether the respectively calculated heat energy can be emitted at the respective heating element in a first time interval predetermined by the start value of the desired speed and a predeterminable remaining time. If so, a printing procedure follows in which the beginning of the printing procedure ensues using the end value of the desired speed.

In a method for controlling a print head with a number of printing elements operating according to the thermotransfer principle, an energy quantity is fed to a printing element in a feed step in order to transfer ink from an ink carrier device associated with the print head to a substrate associated with the ink carrier device to generate an image point of a barcode, with the energy quantity being adjusted dependent on the position of the image point in the barcode.
