Definitions
- Electronic signature means that a hash value of the data to be signed is encrypted and this encrypted form is transmitted to the recipient together with the original data.
- a hash value is a form of the original data encrypted or transformed by a one-way function. Since the recipient knows who the data comes from, he can decrypt the encrypted data again with a key assigned to the sender, which he knows, and even transform the received original data using the hash function which is also known to him and from the match of the transformed ones Original data with the decrypted data derive the correctness of the signature and in this way clearly assign the received data to the named recipient.
- Devices or systems for generating electronic signatures that is to say generally for encrypting data, usually have a PC which is usually provided with peripheral devices such as a screen, a keyboard and a printer.
- the data is advantageously encrypted with the aid of chip cards in which the encryption algorithm or the encryption algorithms and the secret key or keys assigned to the user are stored. This means that each user can easily carry their key and the algorithm (s) with them in order to use any PC or other media, such as fax or telex devices.
- a chip card reader is required, which, however, is under the control of the operating system of the PC or another data creation and / or transmission medium in today's systems.
- the data to be encrypted Since the data to be encrypted must be in the most compact possible format, it will usually be in a different format than the format shown on the screen at the time of encryption. However, this means that the user can never be sure whether the data to be encrypted really corresponds to the data that is currently displayed on the screen. This is all the more so since electronic signatures are usefully used on networked PCs in order to be able to send the documents signed in this way directly from the PC via the network to the recipient. However, this opens up the possibility that files are imported into the PC via the network, which enable manipulation of the data to be encrypted.
- the object of the present invention is therefore to provide a device in which it can be ensured that the data to be signed really correspond to the data provided by the user.
- drivers for example screen drivers or printer drivers
- These drivers are programs that create a data format from a standard format that can be read by the corresponding monitor or printer. It is therefore customary to provide the possibility in a PC to create such a standard format from the PC's own format. Programs are also used for this purpose, which are referred to as front-end drivers, while the peripheral device drivers are referred to as back-end drivers.
- the invention now provides for a certified data carrier read / write device to be provided in a line between the PC and a displaying peripheral device or in parallel to the peripheral device, into which the data to be signed are read on the one hand and this data on the displaying peripheral device, for example egg, on the other hand -
- a printer or a screen to check the correctness can be displayed.
- the creation of the electronic signature or the return of the signed data to the PC takes place only after an active confirmation by the user. This ensures that this confirmation process cannot be controlled by the PC.
- the advantage of this device is that the user can check on the indicating peripheral device which data has been read into the chip card for signature.
- the display is not as convenient as that of known word processing programs on the market, it is ensured that it is the same format as the data that was read into the chip card, and in this way no manipulation by another program that may be contained in the PC is carried out could be.
- the data carrier read / write device is completely self-sufficient and cannot be controlled by the PC, but only receives data from there, misuse is impossible. The prerequisite for this is, however, that this data carrier read / write device
- the data carrier read / write device advantageously has a button or another actuating element which the signatory must press before the signed document or is created and / or sent S chrift Cultures done. As with the previous signature, it is up to the signatory whether he wants to check the correctness of the document or whether he simply signs, for example, by pressing a button. In any case, the actuation of the actuating element means a clear expression of will.
- the figure shows a simplified representation of the principle of the invention.
- the figure shows a personal computer as data creation device 1.
- data creation device 1 is connected via lines 5 to a peripheral display device 2, which in the example shown is a printer.
- a data carrier read / write device 3 is connected in between.
- the display device 2 is part of the data carrier read / write device 3.
- the data carrier read / write device 3 has an input protector 7 into which a chip card (not shown) can be inserted.
- This chip card contains the algorithm and the secret key, by means of which data which are transmitted from the data creation device 1 via the line 5 to the data carrier read / write device 3 are encrypted, that is to say processed to an electronic signature.
- the electronic signature representing Locks ⁇ rarely data is via a line 8 back to er ⁇ provision device 1 transmitted.
- the lines 5 and 8 can of course also be designed as a bidirectional line.
- the essential component of the invention is an actuating element 4, which in the example shown is a button to be pressed by the user. Creation and / or transmission from the data carrier read / write device 3 to the data creation device 1 of the electronic signature takes place only after the user has pressed this button 4.
- the device according to the invention ensures that the data to be encrypted in the chip card inserted into the data carrier read / write device 3 are identical to the data represented by the display device 2, the signature is clear and is activated by pressing the button 4. which also represents a clear expression of will in the legal sense.
- a prerequisite for general recognition of such an electronic signature will, however, be that the data carrier read / write device 3 is "certified" by an authorized authority, that is to say that it has been tested and sealed properly.
