Description of the invention (1) < Utilization field in the industry > The person who installs, especially the device that has the function of expressing the message data sent from the base station (Base station). < Prior art > As a mobile radio communication system in the past, there is usually a selective call system, which is a well-known communication method. As for the selective call system, the selective call signal is commonly used as shown in Fig. 8. The selective call signal is like dividing a frame (frame) into multiple groups (Group) by time share. ) (In the figure, it is divided into η groups), and this group is still divided into synchronous words (word) and plural call words (word) in the time-sharing mode (as shown in (b)). m language). Furthermore, these call phrases are shown in (c), and are composed of individual number symbols (ID codes) and message codes of selective call receivers. When calling the designated selective call receiver, the caller dials the telephone number corresponding to the selective call receiver, completes the connection with the base station, and sends the message information to the base station (BS). Then, the base station first generates the ID code pre-programmed in the selective call receiver together with the message code that encodes the message information, and then forms a frame (fra-me) complex group. Select the calling language of the space to be called group to which the calling receiver belongs, insert each of the above ID code and message code and send it. On the one hand, the pseudo configuration shown in Figure 9 is an example of a selective call receiver. In the same figure, the selective call signal sent from the base station is passed through the antenna (please read the precautions on the back before filling the nest page). This paper is used in the national standard (CNS) A4 specification (210x297 male dragon) -3-A 6 13 6 Printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of Invention (2) 1 After being received by the wireless circuit 2, demodulated by the demodulation circuit 3 and input to the control circuit 4. The control circuit 4 compares the ID code contained in the demodulated selective call signal with the ID code of the unit previously recorded in the ID-ROM 5 in the ID number memory. Then according to the comparison result, if the detected two symbols are consistent, then the receiver is considered to be called, and then the beep signal is supplied to the speaker 7 via the drive circuit 6, so that the loudspeaker emits a calling sound, thereby informing the call Check-in staff, the above call sound can be cut off by pressing the stop switch 11. The above control circuit 4 when the above ID codes are detected to be consistent, the ID code corrects the received message code and performs demodulation, and then supplies the demodulated message data to the display drive circuit 8, and then makes The message information is displayed on the liquid crystal display (LCD) 9. When the check-in operator gets the call notification, the above LCD 9 can know the information sent by the caller. In addition, the above received message code is transferred to the message memory (Μ — RA Μ) 10 and recorded with 100 million, the message code of 100 million recorded in the message memory 10 is displayed when the indication switch 12 is pressed On the LCD9. < Problems to be solved > However, as far as the conventional selective call receiver is concerned, when a call comes in, the received message is unconditionally indicated on the LCD 9, and after receiving, as long as the simple operation of the switch 12 is pressed, the The received message recorded in the message storage 10 is displayed on the LCD 9. For this reason, Gu Lu sometimes leaks the confidentiality of received messages. In addition, in order to keep the responsibilities of the received message confidential, you must keep the received message (please read the precautions on the back and then fill out this page). The standard size of this paper is China National Standard (CNS) A4. (210x29 '〖mm>) -4-321808 Λ 6 13 6 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Invention Instructions (3) All information information is encrypted, however, in order to interpret the password, you must enter it first Only the prescribed password (pass word) can express the received message in the original text. Some people have thought about it, but this conventional method, because all the message data is unconditionally encrypted, so for those In the case of message data with a low level of confidentiality that does not need to be kept secret, in order to interpret the message, the specified password must also be entered, so the operation of the message to display received information becomes very troublesome. The object of the present invention is to provide a radio communication terminal device which can give important reception message information confidentiality and is easy to operate. Another object of the present invention is to provide a radio communication terminal device that can encrypt received message information and impart confidentiality, and can confirm the received message data without having to perform a password interpretation operation. < Means for solving the problem > In order to achieve the above purpose, the present invention will correspond to the encryption control information for each received message information whether to perform encryption. To display the received message information on the display means, use the encryption means to read out the corresponding encryption control information from the above-mentioned billion-counting means, and determine whether it is necessary to encrypt, if it is determined that it is necessary to encrypt , According to the ciphering rules, the information received above will be ciphered and then expressed. Furthermore, in order to achieve the above-mentioned other purpose, the invention will replace the text or symbol of the received message data with the text body or symbol on the crossbones of the other relative text or symbol. Password (please read the precautions on the back before writing this page) Install-Line < This paper standard is used in a standard (CNS) A 4 specifications (210X297 male dragon) Λ 6 13 6 Central Bureau of Standards Printed by Beigong Consumer Cooperative V. Description of the invention (4) Replace the cryptographic rules by the tokenization, and record the billions in the cryptographic means of the cryptographic rules, and use the cryptographic means when displaying the above-mentioned received message information on the representation means The above-mentioned received message Qianbao will be given to the cipherer according to the ciphering rules replaced by the ciphering means in the above ciphering rules. Furthermore, the present invention records the plural replacement cryptographic rules in billions of cryptographic intelligence recording methods, and at the same time, in advance, which group of replacement cryptographic rules corresponding to each received message intelligence is used in the above The cryptographic control information is recorded in billions. When the received message information is to be displayed, the corresponding cryptographic rule corresponding to the received cryptographic rule is used, and the above cryptographic control information is used to discriminate and based on the substituted cryptographic rule ， Encrypt the information of each received message for display. < Function > According to the device of the present invention, it is possible to separately set whether it is necessary to perform encryption according to each received message data, and to encrypt important received messages to maintain confidentiality. It is displayed, and for receiving information that is not very important, it can be directly displayed without being encrypted. For this reason, it is very easy to confirm that it is not necessary to perform decryption for the received message information that is less important, so that both a device that maintains confidentiality and a simple device can be used. Furthermore, as far as other inventions are concerned, because it is relatively easy to receive the message information using decryption instead of the cryptographic rules to execute and then express them, it is impossible for a third party who is not familiar with the cryptographic rules to know correctly Receiving information content, but for operators who are familiar with encryption rules (please read the precautions on the back and then write this page). Packing and Ordering-Line-1 6 _ Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs As far as explanation (5) is concerned, it is easier to interpret the meaning of the original text from the information of the encrypted received message displayed. Therefore, not only the confidentiality of the received message can be maintained, but also the user can confirm the received message information without any special operation to decrypt it, so as to mention its ease of use. In addition, according to the device of the present invention, there are multiple sets of replacement encryption rules, and these replacement encryption rules are designated as selectable states for each received message information, so the third party ’s Confidentiality. < Example 2 > The following is an explanation of an example applicable to the selective call receiver. Figure 1 shows the block diagram of its composition. In addition, if the same parts as in Figure 9 above are marked with the same symbols in the same figure, the detailed description is omitted. In the selective call receiver shown in this embodiment, a mode switch 1 3, a cryptographic information storage (N-RAM) 14 and a cryptographic circuit 15 are additionally provided. The open mode 13 is mainly used to specify the input mode of the cryptographic rules, and the cryptographic information storage unit 14 enters the cryptographic information input by the above cryptographic information into the modal, respectively corresponding to the message storage Each number of the device 10 is stored and recorded in billions. For encrypted information, for example, as shown in Figure 6, Ye is made up of guard pattern (pro-tection pattern) information and password (Pass word). There are " 1 " 2 '' '3 ", 4〃, etc. in the guard style information, and these numbers correspond to "no encryption", "replace all with X", "1 shift password" Rules "," 2 Shift Encryption Rules "<" 3 Shift Encryption Rules ", and then the password (Pass word (please read the precautions on the back before filling out this page) This paper ruler A Xiao used in a The B standard (CNS) A4 specification (210x297 g; ":) Λ 6 13 6 Printed by the Employees Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. The invention description (6)) is formed by, for example, a four-digit string. As shown in Fig. 6 above, the encryption circuit 15 傜 has three alternative encryption rules, namely, "1 shift", "2 shift", and "3 shift". These All of the encryption rules are based on the encryption rules shown in the control circuit 40, and the received message is reported to be encrypted. In addition, the encryption circuit 15 and Ye, when the self-control circuit 40 has an instruction corresponding to the above * 1 ", it sends out the message information composed entirely of ''. However, the control circuit 40 is, for example, a microcomputer as the main control unit, and the display function of the received message is provided with a cryptographic information input control means 41, a cryptographic display control means 42, and a password decryption display control means 4 3. As for the cryptographic information input control means 41, like in the call standby state, when the modal switch Uode switch 1 13 is operated, it becomes the cryptographic information input mode, and in this state, use each switch The operations of 11, 12, 13 and so on, the input of the encrypted information is recorded in a series of control operations in one of the memory 14 of the password information. The cryptographic representation control means 42 executes the cryptographic information stored in the cryptographic information storage 14 when the representation switch 12 is pressed in the call standby state to determine whether it is to be cryptographic, or to replace all with meters, Or what kind of shift ciphering rules should be used to implement ciphering, etc., and then control the execution according to the judgment result. In the end, the received message information should remain unchanged, or all should be replaced with ¥, or the password should be given according to each shift ciphering rule And then displayed on the LCD 9 to control the work. Password release indication control means 43, Yu borrowed the above password expression (please read the notes on the back before filling in this page) -8-321808 The Ministry of Economic Affairs Central Standards Bureau Beigong Consumer Cooperation Du Duan Λ 6 13 6 V. Inventions Description (7) The control means 42 indicates that the ciphered reception message information is displayed in the state of the LCD 9 when the modal switch 13 is operated. Then control the input of the password, and at the same time, use the entered password as the encrypted information and compare it with the password recorded in advance. If the two passwords are consistent with each other, the password of the encrypted information information in the display will be released. , And then show the original text. The operation of the selective call receiver constructed as described above will be described in accordance with the control sequence of the control circuit 40. The message memory 10 has six message-recording fields (corresponding to storage numbers 1 to 6). In these message-recording fields, Ye explained that he had received message information in the state of having recorded messages. In the standby state, the control circuit 4 ◦As shown in Figure 2, at step 2 a, it monitors whether the machine group to which the machine belongs enters the reception period, and once it is found to enter the reception period of these groups, it shifts to the reception control. In the case of the reception control, the ID code contained in the reception selective call signal is compared with the ID code of the local machine recorded in the ID-ROM 5. Then, if the two ID codes match, a beep will sound from the speaker, and the message information inserted into the above-mentioned selective call reception signal will be interpreted and displayed on the LCD9. Furthermore, the received message intelligence replaces the message memory area of the message memory 10, and the earliest received message information field is still recorded in the 100 million received message information and recorded in the billion Of it. The control circuit performs the operation monitoring and display switch 12 in step 2 b, and the operation monitoring and display switch 13 in step 2 c. 210x297 public; ¢) (Please read the precautions on the back before filling out this page) Binding · Order · — 9 — Λ 6 13 6 Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (8) Display switch 12 When pressed, the received message information stored in the message storage 10 is transferred to the control state. Furthermore, when it is confirmed that the modal open 13 is operated, the control circuit 40 becomes the input mode of the encrypted information, and performs the input control operation of the encrypted information. At present, if the user who calls the receiver is selected to set the encrypted information, and the modal switch 13 is pressed, then the control circuit 40 is as shown in FIG. 3 (a), and the message is first step 3a. After the storage number η (n = l ~ 6) of the memory 10 is set to the initial setting of n = l, in step 3b, first read the received message information stored in the memory number 1 of the message storage 10, and then read The received message is displayed on the LCD 9, and the received message information only indicates that it disappears within a certain time (for example, a few seconds). Therefore, the user can confirm the received message information recorded in the storage number 1 of the message storage 10 from the display. Furthermore, the control circuit 40 will generate the initial value of the guard pattern information at step 3C, such as " 1 ", and then display it on the LCD 9 in an extinct manner. As such, when the protection pattern information is displayed, the control circuit 40 repeatedly monitors the operation of each modal switch 13 at steps 3d, 3e, 3f, and stops the operation of the switch 11 and the display switch 12 operating. Then, in this state, when the user presses the display switch 12 to select other guard style information, the control circuit 40 will step 3 g, increase the guard style information value, and select the next one The value (for example, 2), and then return to step 3c to display the value on LCD9, and then perform the same control work repeatedly. Therefore, every time you press the switch 12, LCD9 displays the guard sample in sequence (please read Please fill out the notes on the back and then fill out this page) Binding-Order * This paper size is used in a standard (CNS) A 4 specifications (210x297 public release) -10-Λ 6 13 6 Beicong consumption of the Central Standards Bureau of the Ministry of Economic Affairs The cooperative prints 5. The description of invention (9) type information, then when the desired guard style information is displayed, if the user presses the stop switch 11, the control circuit 40 judges that the guard style currently displayed is selected Information, and temporarily store the information in the recorder in the control circuit 40 at step 3h. Again and again, when the modal switch 13 is pressed, the control circuit 40 judges that the next next memory number has been selected and moves from step 3d to step 3 r * in Figure 3 (b), Here, it is determined whether the storage number η has reached the maximum value of 6. If η = 6 is not reached, increase the storage number η in step 3s, and select the next storage number (for example, 2 at this time), then return to step 3b, and enter the guard style information for the stored number 2 Monitor and control work. From now on, in the same way, every time the modal switch 13 is pressed, the next stored number is selected in sequence, and then the operation of the modal switch 13 is followed, and when the value of the stored number η becomes the maximum value 6, , It is judged that the input operation of the encrypted information has been completed, and the call standby state is restored. Therefore, when the input of the above-mentioned guard style information is set, the control circuit 40 then shifts from step 3h to step 3 i of FIG. 3 (b), and then the password number m (m = l ~ 4) ) After setting m = l, the initial value of the first digit of the password (for example, 1) is displayed in step 3 j. Then, in step 3 k and step 3, the operation of each stop switch 1 1 and display switch 12 is repeated. In this state, when the user presses the indicating switch 12, the control circuit 40 returns to the step 3 j after increasing the password value at step 3m, and displays the increased password value, and then repeats The same control works. Therefore, when the user presses the table every time (please read the precautions on the back and then fill out this page), install it. Line < -11-Λ 6 13 6 Printed by Beigong Consumer Cooperative of Central Bureau of Standards, Ministry of Economic Affairs (10) When the switch 12 is displayed, the LCD 9 sequentially displays the password value 2, 3, and 4 of the first digit. Then, when the user presses the stop switch 11 in the state indicated by the desired value, the control circuit 40 judges that the value of the first digit of the password has been selected, and shifts to step 3η, which means The value is temporarily stored in the recorder in the control circuit 40. Then it is determined whether the password value of all digits (4 digits) of the password is set at step 30. If it is not completed, increase the number of digits m at step 3ρ (in this case m = 2) and then return to step 3 j In the future, the same control work will be executed repeatedly. Then, after the value of all digits of the password is set, the control circuit 40 determines that the setting of the cryptographic information for the stored number 1 has been completed, and moves to step 3q, where it will be saved in the control The cryptographic information formed by the guard style information and password of the recorder in the circuit 40 is transferred to the cryptographic information storage 14, and the billion is recorded in the field corresponding to the storage number 1 in the cryptographic information storage 14 . In this way, a setting procedure for storing the encrypted information of the number is completed. Then, the control circuit 40 determines whether the setting of the encryption information of all the stored numbers is completed at step 3 r. If it is not completed, after selecting the next stored number η at step 3s, it returns to step 3b and repeats the same operation. Control work. On the one hand, when the setting of the encrypted information of all stored numbers is completed, the call standby state is restored. As such, in a state where the desired encrypted information is set for each stored number of the message storage 10, if the user presses the presentation switch 12 during the call standby period, the control circuit 40 executes the encrypted presentation control later ( Please read the precautions on the back before writing this page.)

That is, as shown in Fig. 4, before step 4a, select the storage number i of the received message information with the latest reception timing of 100 million in the storage number of the message memory 10, and then at step 4b Corresponding to the encrypted information of the stored number i. It is read from the encrypted information storage 14 and the step 4c is used to discriminate its guard pattern information. According to the judgment result, if the reading guard style information is 〃, the control circuit 40 judges that it is not necessary to apply cryptography, and then at step 4d, the memory area corresponding to the storage number i of the message storage 10 is stored out Receive message information, and display the received message information on LCD 9 in step 4 e as it is. Therefore, if the user thinks that it is not important to receive the message information, and 0 corresponds to the stored number of billions, and it is set as the guard style information in advance, as long as the P message receiving information display is turned on, you can immediately confirm the received message . When displaying the received message information, the control circuit 40 repeatedly executes each modal switch 13 and stops the open blue Ϊ1, and indicates the operation monitoring operation of the switch 12 at steps -4Ϊ, 4k. Then, when the switch 12 is pressed, the stored number i is increased at step 4m, and returns to step 4b, after which the same control work is repeated. On the one hand, when the stop switch is pressed, the received message information is turned off at step 4η, and then the standby state is restored. On the other hand, if the guard pattern information corresponding to the stored number i is now set to '' 1 〃, the control circuit 4 determines that it is necessary to replace the received message information with ¥ and move from step 4c to 4 f. This cryptographic circuit 15 generates the message information only formed from the origin as shown in FIG. 7, and displays the message information on the LCD 9 at step 4g.

Description of Invention (12) The information of the received message of the code i stored in the number i only represents the password message of ¥. For this reason, if the third party wants to pirate Jiyi to receive the message information at the storage number i above, it cannot confirm the received message information. In addition, if the information of the received message is replaced by ¥, it is impossible to confirm the content of the received message even by itself. However, the above-mentioned received message information can be confirmed in the following manner. Also, when the modal switch 13 is opened in the state indicated by the above-mentioned message, the control circuit 40 detects the modal switch 13 at step 4j. In the operation state, the password will be released to indicate the control work. That is, as shown in Fig. 5, in step 5a, the first digit of the password is selected, and then in step 5b, the initial value of the password of the first digit (for example, 1) is displayed on the LCD 9. Then, in steps 5c and 5d, the operation monitoring of each stop switch 11 and the operation monitoring of the display switch 12 are repeatedly performed. In this state, when the user presses the display switch 12, the control circuit 40 moves to step 5e, where the above password value is increased and returns to step 5b, and then the next password value (2 ) Is displayed on LCD9. The following are the same. Each time the user presses the display switch 12, the password value is displayed on the LCD 9 in the order of 3, 4, 5 ... Then, when the user presses the stop switch in the state where the specified password value is displayed, the control circuit 40 determines that the password value has been selected, and keeps the selected password value in the control circuit 40 in step 5 f The recorder. This completes the input of the first digit of the password. After the input of the first digit of the password is completed, the control circuit 40 continues to determine whether all the digits (4 digits) of the password have the input password value at step 5 g, and if there are uninput digits, then Increase the number of passwords (please read the precautions on the back before writing this page) Install & Thread · Use the standard of this paper (CNS) A4 specifications (210x297 public goods) _ 14 One Ministry of Economic Affairs Printed by the Bureau of Standards, Pongong Consumer Cooperative V.

Then, when it is confirmed that all four digits of the password are input, the control circuit 40B11 compares the password just entered at step 5 i with the password corresponding to the billion recorded in the storage number i in the encrypted information storage 14. Then, if it is found that the two passwords are consistent with each other, it will be transferred. Step 4 d, from the billions of fields corresponding to the storage number i of the message storage 1 ◦, will receive the received message information and indicate that it is in the step Stage 4e. However, the received message information of the stored number i is displayed on the LCD 9 in the original text state, so the user uses this indication to know the content of the received message information. Furthermore, if the passwords do not match, the display is turned off and the call standby state is restored. Furthermore, if the guard pattern information set corresponding to the storage number i is 2, 3, or 4, the control circuit 40 performs the following cryptographic representation control operation. That is, the control circuit 40 first free steps 4h, corresponding to the memory area of the storage number i of the message memory 10, the received message information is obtained, and the received message (receiving message) information is transferred to the encryption circuit 15. At the same time, the control circuit 40 generates an indication message corresponding to the above-mentioned identified guard pattern information shift encryption rule, and outputs the indication information to the encryption circuit 15. For example, assuming now that the guard style information is a 2 〃, the data required to indicate the 1 shift encryption rule will be input to the encryption circuit 15. In this case, the encryption circuit 15 performs the encryption of the received message data according to the shift encryption rules indicated by the above instruction data. For example, when the 1 shift encryption rule is instructed, as shown in Figure 7, the addition of 1 is performed every time in the value of the received message data, thereby completing 1 paper scale while using the Chinese standard for the poor family ( CNS) A4 specifications (210 father, 297 male dragon) (please read the precautions before filling in this page) -15-A 6 ΙΪ6 Printed by the Beigong Consumer Cooperative of the Central Bureau of Economics, Ministry of Economy V. Description of invention ( 14) The work of shift encryption. Furthermore, when the 2 shift ciphering rule is instructed, the addition of 2 is performed every time in the value of the received message data, thereby completing the work of 2 shift ciphering. Furthermore, when the 3 shift encryption rule is instructed, the addition of 3 is performed every time in the value of the received message data, thereby completing the work of 3 shift encryption. Then, the received message data which is encrypted in the encryption circuit 15 is supplied to the display driving circuit 8 through the control circuit 40, and then displayed on the LCD 9. Therefore, even if the received message data is encrypted through encryption, even if it is seen by a third party who does not understand the password rule, the correct content cannot be read, so the confidentiality of the received message data can be ensured. Furthermore, when users who are familiar with the rules of shift ciphering see it, they can simply decipher the data content by means of mental arithmetic. Therefore, in order to cancel the password, it is not necessary to perform the input operation of the password, so the work efficiency can be improved. In addition, the received message data that has been encrypted according to the above encryption rules may be inputted with the password as in the case of the above-mentioned rice, and the original data will be displayed after the password is released. According to this embodiment described above, it has the following effects. ①, because the encrypted data is set in each message storage area of each message storage 10, and according to the encrypted data, each value-received message data is separately displayed to the controller, so it can also be received separately for each The message data is expressed after being encrypted, or directly expressed without being encrypted. Therefore, for example, the message data of higher importance is encrypted before it is indicated to ensure confidentiality. On the one hand, information that is not necessary for confidentiality can be directly expressed. For this reason, it is better to connect all of them (please read the precautions on the back before writing this page) to order _ This paper is used in the ffl national standard (CNS) T4 specification (210x297 g; g :) -16- Λ 6 »6 Printed by Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of invention (15) The situation in which the collected information is collected and then given a cryptographic representation, which can improve the efficiency of use. ② As the encryption rules of the received message data in this case are pseudo-shift encryption rules, so the third party who does not encrypt the rules has sufficient confidentiality, and for users who are familiar with the encryption rules , You can use the mental arithmetic method to simply solve it. Therefore, in order to interpret the password, it is not necessary to input the password, and the result is to improve the efficiency of use. ③ Because multiple encryption rules can be prepared in this case, and these encryption rules can be set to be selectable for each received message data, it is more difficult for a third party to interpret, which can improve Confidentiality. This kind of effect is very important for the selective call receiver in this embodiment to adopt the shift encryption rules that are easier to interpret. This is very important for ensuring a certain degree of confidentiality. Furthermore, the present invention is not limited by the above-mentioned embodiment. For example, in the above-mentioned embodiment, it is assumed that the control method is encrypted for the received message data stored in the message storage 10, but for the call, it is received. The message data can also be controlled by cryptographic representation. In addition, in the above embodiment, the message data is composed of numeric strings, and it can be applied if it is composed of other katakana or English letters. For example, in the case of pseudonyms Η, it is possible to shift '" 7 〃 to Α V ", but when English letters are used, it is ok to shift a A " to v B 〃. In addition, the shift direction can also be set in the reverse direction, and the shift amount can also be set arbitrarily.
