Abstract: In a method and arrangement for variable generation of cryptographic securities of communications in a host device, for cryptographic security of a communication for a first purpose a first signature is used and for cryptographic security of a communication for a second purpose a second signature is used, the signatures being differentiated from each other by the type of their generation. A cryptologic module has a number of logic circuits and a changeover switch and is arranged externally of the postal security device and is connected at its output with an information input of the postal security device that has a logic circuit that applies a digital signal algorithm to the output signal supplied by the output in order to generate a signature.

Abstract: 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.

Abstract: In a method and arrangement for exchanging data between a first processing unit, containing first status information about the first data processing unit, and a second data processing unit, containing second status information about the first data processing unit, data are exchanged between the first and second units during transactions that include a status-changing transaction, which can be of two different types. Upon a successful completion of the status-changing transaction, the first and second status information are revised so that they match. Upon an unsuccessful completion of the status-changing transaction, at least one of the first and second status information is set dependent on the type of the status-changing transaction.

Abstract: In a method and arrangement for securely exchanging data between a first data processing unit and a second data processing unit, a secure communication channel is established between the first data processing unit and the second data processing unit in a communication configuration step, and a first message is transmitted from the second data processing unit to the first data processing unit via the secure communication channel in a data transmission step. During the data transmission step, the second data processing unit generates a second message by appending a predetermined annex to the first message and a third message by encrypting the second message using a secret key that is available only in the first data processing unit and in the second data processing unit and then transmits the third message to the first data processing unit.

Abstract: In a method and arrangement for data follow-up for warmup cycles of an ink jet print head, a memory stores warmup data of an ink jet print head and a control unit is provided for the driving the ink jet print head and is programmed to implement at least one measurement of the ambient temperature and to access the memory dependent thereon and dependent on predetermined, stored conditions in order to implement a data follow-up corresponding to the temperature-related, history-related and/or user-related conditions for a fast start. Storage of warmup data and data for a first condition ensues upon new installation of an ink cartridge before the first use thereof, and parameter data for second conditions are determined for a fast start given repeated use, and the appertaining warmup data are computationally or tabularly determined given current second conditions.

In order to prevent the housing from being opened without leaving trace of the opening, there is provided at least one covering device on and/or in the first or second housing part. The covering device blocks the access to the connecting device and can only be removed from the first or second housing part with noticeable damage being caused.

Abstract: In a method for real-time registration having high protection against tampering by means of a security module, an encrypted initial security value for translog file analyzers is made available an unencrypted real-time message is secured by appending an authentication code that the security module generates by inserting a current security value into an algorithm for authentication code for each real-time message that is likewise employed by each translog file analyzer. The first security value is formed according to a first mathematical function known to the translog file analyzer that allows a derivation of following security values. The authentication code is formed according to a second mathematical function known to the translog analyzer that is applied to the real-time message and to the current security value and that serves for the verification of the real-time message.

Abstract: In an arrangement to generate a print image for franking and postmarking machines a control unit electronically controls a printer and storage unit for data that are printed in predetermined sections of the print image. Controlled by the electronic control unit, a selected section is printed with special postal information by the printer in a second position to the left next to a first position. The special postal information characterize a private mail carrier. The electronic control unit of the device is connected with a mail processor that determines data that enable mail piece processing and sorting at the private mail carrier.

Abstract: In a method and apparatus for generating a print image, particularly a franking imprint, on a first image carrier composed of at least one first partial image and a second partial image offset thereto transversely relative to a first direction, whereby a relative motion between a print head and an image carrier is generated along a first direction in a first step for generating the first partial image. A transverse offset between the print head and the image carrier is generated in a second direction proceeding transversely to the first direction in a second step. A relative motion between the print head and the image carrier is generated along the first direction in a third step for generating the second partial image. The waiting time interval between the end of the printing event of the first step and the beginning of the printing event of the third step has a length that is varied according to a prescribed function to prevent tampering.

The postage meter machine serial number is entered in a step separate therefrom. As needed, data can be loaded or selected with a specific, country-specific and/or carrier-specific chip card in order to finally configure the postage meter machine.

Abstract: An arrangement and a method for modifying the functionality of a security module employ a start loading program stored in a FLASH program memory for reprogramming the FLASH program memory by copying a portion of the start loading program into a main memory of the security module. Data of at least a part of an application program, an appertaining certificate code and identifier data are offered in the communication interface of the security module. The data of the part of the application program are stored on a free memory location of the FLASH program memory when the identifier data characterize a successor status for the stored status. The authenticity of the loaded part of the application program is checked with the certificate code, and given authenticity of the loaded part of the application program, it is stored as valid.

Abstract: A method of opening a security housing that requires authorization and unlocking moves the printing module transversely by a transverse mover into an additional unlocked position, as a result of which, the security housing or an access thereto is unlocked. The configuration has a mechanical locking or element and a printing module. The printing module is mounted such that it can be moved transversely to the transporting direction, for mechanically releasing the lock of a security-housing part directly or indirectly, by the security-housing part only being released once an additional security-housing part has been unlocked. The latter has a locking element that is disposed in the interior of the security housing and can be actuated by the printing module.

Abstract: In a method and arrangement for reducing printer errors while printing on a print medium in a mail processing device a print data controller for pixel data editing while printing with a printhead contains logic for error reduction having a resettable encoder clock counter. Encoder pulses corresponding to the relative motion between the printer and the print medium are generated. Using these pulses, incremental and decremental counting occurs for evaluating a condition with diminished time spacing of neighboring encoder pulses. A direct memory access (DMA) for a data string of binary pixel data ensues for implementing a print cycle for the data string, and a further direct memory access ensues during the print cycle for a next data string.

Abstract: 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.
