Description

The invention relates to an arrangement between input and output devices for data processing Systems for encryption and decryption as well as for the transmission of information in operation

using register, diode-equipped matrix or Allocation circuits.

A circuit for generating characters in binary code, for example, has become known from a diode-equipped selection circuit and a counting chain (German Auslegeschrifi 617).

A considerable saving in terms of diodes should be achieved with this circuit. This becomes through it achieves that the character to be sent determining contacts via the type of Kreuzschieuenverteilern built-up selection circuit with one electrode one selected by the «

It has been found that this task turns out to be of particular advantage that the line and can be solved in a fan manner by connecting the implement column address lines for the driver matrix outputs of the bistable stages of the register under 45 identical combined encryption and decryption interconnection of AND circuits for retrieval matrices are connected, which are from the control unit Switch impulses with the output terminals for encrypted either to encryption or decryption Information are connected and let the implement-.

With the invention, all desired split line pairs of two identical, combined codings can still be created without changing the combined creation and creation built up as diode encryption and decryption matrices in connection matrices, their row lines simply via row and coding matrices and through column address lines and allocators, the row pins or the like can be passed through into the allocator and column lines of a driver matrix for radio can be passed through. This applies to both the entity and the function elements for outputting unencrypted information as well as for the encryption. The allocators are controlled in such a way that each row and column are structured in such a way that each information address line pair can be assigned to an individual code symbol of a key contact of an input keyboard for unencrypted codes via an allocator,

The reset inputs of the flip-flops 80, 86, 90 to 94, 99, 101, 104 and 108 are supplied with reset pulses via the bus 74, and the control inputs of the flip-flops 86 and 101 are supplied with clock pulses via the bus 84, which are also on the reset inputs of the flip-flops 99 and 108 are connected.

F i g. 4 shows a detailed circuit diagram of a preferred, per se known flip-flop with base control of its pnp transistors, which is used in principle both in register 8 and in control unit 9. The coupling resistors RK ₁ and RK- supply the transistors with bias voltage, whereas the coupling capacitors CK ₁ and C ₂ are used to short-circuit the coupling resistors during the switching process and thereby achieve the highest possible efficiency. The emitter resistor ER and the base resistors RB are at + 12 V. The emitter resistor can also be bridged by a capacitor, so the transistors 7 ″, and T ₂ achieve high gain during the switching operations. The inputs are connected to circuit points A and B , with decoupling diodes D being provided. The control inputs are connected to the diodes D via input resistors RE and the other inputs via capacitors.

Finally, FIG. 5 shows a code table of a coding used, for example. the Filled in dots represent the implementation values, the unfilled dots the complementary values. There is a figure-of-eight coding in which the left 4 channels 5 to 8 are the column lines and the right 4 channels 1 to 4 are assigned to the row lines of the driver matrix 12.

By the allocator 52, 520/62 SP 62 and the Z codes shown in Fig. 5 can be associated with any kind of information.

Mode of action

Before commissioning, all flips-flops of the arrangement are brought into their starting position by a generally known actuating pulse on the line 74, in which the signal voltage switch 92 sends a signal voltage of + 12 V to the code contacts 20 via the output terminal 23 K and the line 23, to 20 _{H of} the input device 4 for encrypted information, the output or acknowledgment contacts 50] to 50 _{16 of} the functional elements 65 and the key switches 500 apply.

The desired operating state of the arrangement can then first be set using the keys 95 and 96, respectively prepare.

The switch actuated by key 95 applies control potential in the form of the signal WS * to the signal line 88 via the changeover switch 94, by means of which the working voltage> switch93 is prepared for the driver matrix 12, the working potential of OV via the line 67 to the Zeilon drivers 63 , to 63 ₁₆ and the language drivers 64, to 64 _{1 (i} switch on and off according to signals and clock pulses.

At the same time, the third switching flip-flop 101 is prepared via the signal line 98, which in accordance with clock pulses on the line 84 of the pulses: IELo. is set and, via the output terminal 72 K and the line 72, the output device 5 for the encrypted information is called up by the commands: A Lo . Since the clock pulses appearing on the line 84 are generated as a function of the signals IEE of the input device 4 for encrypted information (strip reader), this works directly on demand (IE Lu.) With the output device ₆ 5 (strip inch) for the encrypted information.

By pressing the button 96 the command: WS is given, which cancels the command: NS. The changeover switch 94 switches over and also switches over the operating voltage switch 93, whereupon the driver matrix 12 is switched on. As a result, the typewriter, assumed for example as an output device, is prepared for writing.

The start button 105 sets the start-stop flip-flop 104 , by means of which the fourth switching flip-flop 108 is prepared to feed the input device 4 (strip reader) for encrypted information via the line 109 in accordance with signals and clock pulses steer. The reset of the start-stop flip-flop 104 follows through the button 106. The switching of the start-stop flip-flop 104 can also take place via the lines 48, 49 from the validity checker.

At the same time, the voltage switch 90 is also prepared via the signal line 107, which switches the combined encryption and decryption matrices 10Z or 10 SP as an encryption or decryption device.

Without making any claim to completeness, the following three preferred modes of operation are intended the arrangement are explained. The first mode of operation is called serial mode. Here the information entered by the strip reader into the arrangement is displayed on both the Typewriter written as well as in def output station punched in a punched tape for encrypted information.
