 The collection operation execution unit 53 (FIG. 9) comprises a delay element 114, an AND element 115, a pulse generator 116, a register 117, counters 118 and 119, a comparison circuit 120 and 121, a multiplexer 122.

 The device operates as follows.

 Before starting work, all the elements and nodes are set to their initial state (not shown to simplify the circuit of setting the device to their initial state): the user password is stored in register 66 of user identification block 2, information about operation information is stored in register 70 of block 3 of the information generation block 3 the user’s bank details and his public key, real-time clock 74 are working, the purchase amount limit established by the bank and the accumulated amount are stored respectively in the registers 102 and 103 of the purchase transaction execution unit 50 purchases, conducted previously by the user, the register 112 of the operation unit 52 prolongation collection stored time deadline for collection of the operation, i.e. operations of transferring the accumulated information from the memory unit 8 to the bank, the accumulated sales amount spent by the user is stored in the register 110 of the sales operation node 51, the final address of the memory unit 8 is stored in the register 117 of the node 53, the next one is stored in the counter 118 of the collection operation node 53 the current address of the recording of information about the operation of the memory unit 8, the information on previously performed operations is stored in the memory unit 8, the user’s private key and system parameters are stored in the electronic digital signature generation unit 4 key generation systems, in the electronic digital signature verification unit 5, the bank’s public key and parameters of the key generation system are stored, the zeros are set at the outputs of the user information input unit 1. All the above registers, counter and real-time clock must be self-powered by battery. The memory unit 8 is made on the basis of non-destructive memory, such as static memory, with battery power.

 The operator-user, when starting work, sequentially presses the keys of the user information input block 1 corresponding to the "Password" digits (not shown), as a result of which the code is set at the outputs of the third group 15 of the information input block 1 by the user, which enters the first group of 15 inputs of the block 2 of the user identification and is recorded in the register 67 on the leading edge of the signal at the second input 16 of block 26 generated at the fourth output of block 1 by pressing the "End password" button (not shown) of information input block 1 user. If the codes in the registers 67 and 66 match, the output is “Equal” to the comparison circuit 68 and then the output of the delay element 69 is set to the signal “logical 1”, which is fed to the input of the element And 65 of the user identification block 2 and to the third input 17 of the information generation block 3 about the operation and then to the third input of AND element 76.

 The “logical 1” signal at the input of the And 65 element allows the user to enter (if necessary) a new password in the password register 66, for which the operator presses the “Change password” button (not shown) of block 1. At the same time, “logical 1” is set at the first input 14 of user identification block 2, which allows writing a new password code to register 66. As a result of successive pressing of buttons corresponding to the new "Password", a new "Password" code is set on the first group of 15 inputs of block 2, which is written to the register 66 on the leading edgeIgna "password input End" formed by pressing the appropriate button (not shown) at the fourth outlet 16 and the incoming unit 1 to the second input unit 16 2.

 The device expects to enter a command (operation code) that determines its operation mode. The operation code is set on the second group of 19 outputs of the user information input unit 1 after pressing the corresponding button (not shown) of the unit 1 and enters the fourth group of 19 inputs of the operation information generation unit 3. At the same time, “logical 1” is established at the first input of AND element 76, coming from the output of OR element 75. At the same time, the first part of information about the operation coming from the outputs of the register 70, hours 74, and input groups 19–22 is formed at the information inputs of register 71 of block 3 block 3.

 The device expects to enter the command "Perform the operation", which is supplied by the operator by pressing the corresponding button (not shown) of block 1. When this button is pressed, the first output 18 of block 1 is set to "logical 1", which goes to the second input of AND 76 through the second input of block 18 3 of generating information about the operation, as a result of which the first part of the information about the operation is generated is recorded on the leading edge of the signal from the output of the And 76 element to the register 71, the outputs of which through the second group 28 of the outputs of the block 3 go to the first Rupp information output device 28 and further to the external device. In parallel, through the delay element 78 at the first output 26 of block 3, the signal "Ready" is set, which is transmitted through the third control output 26 of the device to an external device.

 The device is waiting for the input to the first control input 9 of the device signal "Ready" from an external device.

 The external device generates the second part of information about the operation, which enters through the first group 12 of information inputs of the device to the fifth group 12 of inputs of block 3 and then to the information inputs of register 72.

 When the signal "Ready" from the external device to the first control input 9 of the device, this signal is transmitted to the first input of block 3, as a result of which the second part of the information about the leading edge of this signal is recorded in the register 72 of block 3, in parallel through the And 77 to the output of the delay element 79 is formed by the signal "Start" of the device, on the leading edge of which the first and second parts of the operation information from the registers 71 and 72 through the outputs of the switch 81 are transferred to the register 73, and the first group of inputs com tripod 81 corresponds to the first group of outputs, and the second group of inputs corresponds to the second group of outputs, if the signal at the output “More” of the comparison circuit 80 is logic zero, otherwise the first group of inputs is switched to the second group of outputs, and the second group of inputs to the first group exits.

 The information about the operation generated in the register 73 through the fourth group of 23 outputs of block 3 is fed to the first group of inputs of block 4 of the digital signature generation and to the first group of information inputs of block 8. In parallel, the Start signal from the second output 25 of block 3 is fed to the first inputs of blocks 4 and 5 and to the second input 33 of block 6 and allows the operation of these blocks. In addition, the public key of the external device user is sent to the first group of inputs of the electronic digital signature verification unit 5 from the third group of 24 outputs of the operation information generation unit 3, and the second and first groups of inputs of the operation unit 6 from registers 71 and 72 through the second 28 and the first 27 groups of outputs of block 3 receive respectively the first and second parts of information about the operation.

 Upon receipt of the “Start” signal from the second output 25 of the block 3 to the first input of the block 4, the electronic digital signature generation block 4 generates in accordance with the known algorithm shown in FIG. 10 (GOST R 34.10-94), an electronic digital signature for information about the operation generated on the first group of 23 inputs of block 4. The generated electronic digital signature and the control signal "Signature is formed" from the first group of outputs 30 and from the first output 29 of block 4, respectively through the second group of information outputs and through the fourth control output of the device are transferred to an external device to verify the generated signature in it.

 In parallel, an electronic digital signature is generated in the external device according to a similar procedure. When a signal is received from the external device, the “Signature is formed” through the third control input 10 of the device to the second input of the electronic digital signature verification unit 5, the signature verification begins, the code of which comes from the external device to the third group of inputs of the unit 5 through the second group of information inputs 13 of the device. A well-known signature verification algorithm is shown in Fig. 11 (GOST R 34.10-94). In block 5, the signature of the operation information generated on the second group of 23 inputs of block 5 is verified.

 If the signature is incorrect, then an “error” signal is generated at the first output 31 of block 5, which is fed to the first input of the indication unit 7, and further operation of the device is blocked by the “logical 0” signal at the second output 32 of block 5.

 If the signature is correct, then the “logical 1” signal appears on the second output 32 of block 5, which enters through the first input of block 6 to the fourth input of node 49 and then to the third input of AND 92. In parallel, when the “Start” signal appears from the second output 25 block 3 at the second input 33 of block 6 and, accordingly, at the fifth input of node 49, the operation of decoders 82-85 of this node is allowed. The operation code from the second group of 62 inputs of the node 49, specified by the device operator, is supplied to the information inputs of the decoders 82 and 85, and the operation code set by the operator of the external device is sent to the information inputs of the decoders 83 and 84 from the first group of 59 inputs of the node 49. At the same time, the signal “logical 1” is set on the first or second output of the decoder 82 if the “Sell” or “Buy” operation is set accordingly by the user-operator. On the first or second output of the decoder 83 is set to "logical 1", if the operation "Buy" or "Sale" is set respectively in the external device. Logic 1 is set on the first or second or third output of the decoders 84 and 85 if the operations “Installation” or “Renewal” or “Collection” are set respectively in the user’s device and in the external device in parallel.

 Let the “operation blocking” signals at the outputs 42, 40, 39 of the nodes 53, 52, 50 not be installed (see below), i.e. equal to "logical 0", respectively, at the first, second and third inputs of the node 49 operations control. Then at one of the outputs of the elements And 86-90 the signal is set to "logical 1", which determines the corresponding operation performed by the device. This signal allows the operation of the corresponding node of the block 6 operations (the operation of each node will be described below).

 If the signal “logical 1” is set at the output of the OR element 94, then the “Signature confirmation” signal is generated at the output of the And 92 element and, accordingly, at the seventh output of the node 49, which is transmitted through the sixth output 46 of the operation unit 6 and then transmitted through the second control output of the device external device, and the device itself goes into standby mode of the signal "Signature confirmation" from the external device at the second control input 11 of the device. When the signal "logical 1" appears on the second control input 11 of the device, it enters through the sixth input of node 49 to the second input of the And 93 element, as a result of which the signal "logical 1" corresponding to the signal "Operation completed successfully" is set, which through the second output 43 of the node 49 and, accordingly, the fourth output 43 of the block 6 is transmitted to the recording input of the memory block 8. Information from 1-3 groups of information inputs of the memory unit 8 is written to it at the address set at the output of the multiplexer 122 of the collection operation unit 53, received in block 8 from the fifth group 45 of the outputs of block 6. In parallel, the signal "Operation completed successfully" from the output of the element And 93, through the fourth output 43 of the operation execution unit 6, it goes to the fifth input of the indication unit 7, and the current hell increases by one through the second input and the delay element 114 of the collection operation execution unit 53, the current hell ec recording in the memory unit 8 is output from the multiplexer 122 for the next operation.

 In the register 117 of the collection operation execution unit 53, the final address of the memory unit 8 is stored, in the counter 118, the current address, which are compared by the comparison circuit 121. When the signal “logical 1” appears on the output of the “Less” comparison circuit 121, it is through the first output of the 42 node 53 is fed to the first input of the operation control unit 49 and sets the logic 0 signal at the outputs of the AND 86-89 elements, and thereby blocks the execution of all operations except the Collection operation, i.e. the operation of transmitting the accumulated information from the memory unit 8 to an external device, the user of which is a bank serving the user account of this device. In the register 112 of the node 52 of the extension of the collection period, information is stored on the deadline for the execution of the collection operation. The current real-time code arriving at the second group of inputs 63 of node 52 is compared by comparison circuit 113 with the code stored in register 112. When the signal "logical 1" appears on the output "More" of comparison circuit 113, it enters through the first output 40 of node 52 to the second input 40 of the operation control unit 49 and sets the logic 0 signal at the outputs of the AND 86-88 elements and thereby blocks the execution of all operations, except for the operations "extend the collection period" and "Collection".

 Consider the operation of the nodes of block 6, provided that the signals at the first outputs 42 and 40 of the nodes 53 and 52 are equal to "logical 0".

 Let the operation "Purchase" in the device in question and the corresponding operation "Sale" in the external device be specified. Then, at the output of the element And 86 of node 49, the signal "logical 1" is set, which through the sixth output 54 of the node 49 is fed to the third input of the node 50 of the purchase operation and then to the control inputs of the first and second groups of elements And 95 and 96 and And 98 of this node. Then the information on the previously accumulated amount of purchases from the output of the register 103 through the first group of elements And 95 is fed to the first input of the adder 99, the second input of which through the information inputs of the second group of elements And 96 receives information from the first group 60 of inputs of the node 50 about the current purchase amount, contained in the second part of the operation information. In parallel, information about the current purchase amount from the outputs of the second group of elements And 96 enters through the first group 36 outputs of the node 50 to the second group 36 of inputs of the display unit 7. In parallel, at the output of the subtractor 100, the amount of the user’s cash balance is generated by the device as the difference between the numbers at the output of the adder 99 and at the output of the register 102, which stores the limit on the amount of purchases set by the bank servicing the device’s user account during the “Installation” operation ( see below).

 If the sum of the received balance is negative, then the signal “logical 1” appears at the output of the sign of the result of the subtractor 100, which through the first output 39 of the node 50 and, accordingly, the third 39 input of the node 49 goes to the inverse input of the element And 92 of the node 49, as a result of which the operation is blocked purchase signal "logical 0" at the second control output 46 of the device.

 Otherwise, the device waits for the receipt of the "Confirmation of the amount" signal by the operator-user of the device, which is installed on the second output 34 of the user input block 1 by pressing the corresponding button (not shown) and enters through the fourth input 34 of block 6 and, accordingly, the seventh input 34 node 49 to the second input of the AND element 91, as a result of which the signal "logical 1" is set at the output of the AND 91 element and then at the output of the OR element 94, which allows generating the signal "Operation completed successfully" (see above) at the second output 43 of node 49. When this signal appears at the first input 43 of node 50 of the purchase operation through the And 98 and OR 101 elements, a signal to record information on the amount of purchases installed on the information inputs of this register and generated on the outputs of the adder 99. In parallel, information about the amount of cash balance on the user’s account by the device from the output of the subtractor 100 through the third group 38 of the outputs of the node 50 is transmitted to the fourth group 38 of the inputs of the display unit. This completes the purchase operation.

 When the user sets the operation code "Sale" and in parallel with the corresponding operation of the external device "Buy" at the input of element And 87 of the operation control unit 49, the signal "logical 1" is set, which, through the third output 56 of the node 49, enters the third input 56 of the node 51 and then to the control inputs of the first and second groups of elements And 104 and 105 and the And element 106 of this node. Information about the previously accumulated sales amount from the output of the register 110 through the first group of AND elements 104 is supplied to the first input of the adder 109, the second input of which through the second group of elements AND 105 from the first group of 64 inputs of the node 51 receives information about the current sale amount contained in the register 71 block 3 of the formation of information about the operation. Information about the current sales amount is generated on the first group of outputs 35 of the user information input unit 1, which the user types after setting the Sale code using keys (not shown). When the keys are pressed, information from the first group of outputs 35 of block 2 goes to the first group of 35 inputs of block 7 of the indication and to the inputs of register 71 through the third group of inputs 20 of block 3 of generating information about the operation and is written to register 71 after entering the command "Perform operation" (see . above).

 Upon receipt of the second input 43 of the node 51 and, accordingly, the first input of the And element 106 of the signal from the output of the And 93 element through the second output 43 of the operation control node 49 "Operation completed successfully", information on the accumulated sales amount on the leading edge is recorded in the register 110 from the output of the adder 109 the signal from the output of the OR element 108. From the outputs of the register 110, information through the fourth group 41 of the outputs of block 6 is supplied to the fifth group 41 of the inputs of the block 7 of the display. This completes the "Sale" operation.

 When setting the operation code "Extending the collection period" in parallel in the user device and the external device at the output of the AND element 89 of the operation control unit 49, the signal "logical 1" is set, which initiates the generation of the "Operation completed successfully" signal at the output of the And element 93 through the OR element 94 (see above) and in parallel through the fourth output 58 of the node 49 it enters the second input of the node 52 and then to the second input of the AND element 111 of the node 52. When the "logical 1" signal appears at the output of the And 93 element, it is transmitted through the second output 43 of the node 49 on the first input 43 of the node 52 and then to the first element And 111, as a result of which the information on the new collection deadline established on the first group of 61 inputs of the node 52 is recorded in the register 112 on the leading edge of the signal from the output of the And 111 element. collection period "ends.

 When setting the operation code "Collection" in parallel in the user device and the external device at the output of the AND element 90 of the operation control unit 49, the signal "logical 1" is set, which initiates through the OR element 94 the generation of the signal "Operation completed successfully" at the output of the And 93 element (see . above), and in parallel through the first output 57 of node 49, it enters the first inputs 58 of node 53 of the collection operation and node 51 of the sale operation. On the leading edge of this signal, the pulse generator 116 of the node 53 is started, and in parallel with this signal, the information from the outputs of the counter 119 is switched to the outputs of the multiplexer 122. At the moment of the start of the pulse generator 116, the value of the counter 119 is zero, i.e. through the first group of outputs 45 of node 53 at the address inputs 45 of memory block 8, the initial (zero) address is set at the initial moment, and the current address is set in counter 118. Pulses from the output of generator 116 are supplied to the counting input of counter 119 and in parallel through the second output 44 of the node 53, which is the fifth output 44 of the operation unit 6, is fed to the read input 44 of the memory unit 8 and, in parallel, is transmitted through the first control input 44 of the device to an external device. On the leading edge of the pulse at the input 44 of the reading unit 8, information about the operation is read from the memory unit 8 and through the outputs 48 of the memory unit 8, which are the third group of information outputs of the device, is transmitted to an external device. On the trailing edge of the pulse coming from the output of the generator 116 to the counting input of the counter 119, the value of the counter 119 increases by one, i.e. the following address is set at which information from the memory unit 8 is read. In parallel, the information at the outputs of the counters 118 and 119 is compared by the comparison circuit 120. When a logic 1 signal appears at the output of the "Equal" comparison circuit 120, the pulse generator 116 stops and the counter 119 is reset to zero. Upon receipt of the second input 43 of the node 53 from the output of the element And 93 of the operation control unit 49, the counter 118 by the leading edge of the signal from the output of the AND element 115 is reset to zero, and then the value of the counter 118 by the same signal through the delay element 114 is increased by one. In parallel, the signal "Operation completed successfully" is received from the second output 43 of node 49 to the second input 43 of the node 51 for performing the sales operation, as a result of which the signal from the output of the And 107 element through the OR element 108 records zero from the output of the adder 109 in the register of the sales amount 110. On this operation "Collection" ends.

 When setting the operation code "Installation" in parallel in the user's device and the external device (the user of which is the bank), the output of the AND element 88 of the operation control unit 49 sets the signal "logical 1", which initiates the generation of the signal "Operation completed successfully" through the element OR 94 the output of the And 93 element (see above) and in parallel through the fifth output 55 of the node 49 is transmitted to the second input 55 of the node 50 and goes to the second input of the And element 97 of the node 50. When the signal from the output of the And 93 element appears at the first input 43 of the node 50 " Operation h completed successfully "in the register 102 is written on the leading edge of the signal from the output of the element And 97 information about the amount of the purchase limit, installed on the information inputs of this register, received on the first group 60 of the inputs of the node 50. Parallel to the leading edge of the output signal of the element And 97 through the element OR 101 in the register of the amount of purchases 103 is written zero from the output of the adder 99. This completes the operation "Installation".

 After completing any of the operations of the device (successful or unsuccessful), the user, by pressing the Reset button (not shown) of the information input unit 1, brings the device to its original state.

 Thus, the device performs all necessary operations in a system of non-cash electronic settlements and, unlike the prototype, can be used for non-cash electronic settlements between its users.
