It is one of the lost items. In case it is lost for fear of forgetting or losing the key, it is a spare key. Usually the thief is also a convenient way for the thief to enter. An experienced thief can be second easy to forget. Or ask someone to help. Some people know this by hiding at the appropriate position near the door, so it is invisible to mention that the microcomputer, especially the microcontroller, starts 3 in time. In order to avoid the trouble of losing the key, the difficulty of unlocking the thief is increased, and the others are There is no key to enter, there is a secret 'frequency. The combination lock is usually based on a single chip (such as the 8051). It is logical to have an I/O control and drive circuit with a small number of σ to form the door lock mechanism. This access control 201107577 key pad keypad allows the user to wheel in numbers, and some also have a simple display thief, such as a 7 4 display or a small [CD, to tell the operator about the message. If the user enters the correct password, the system will drive the circuit and let the door lock open. The advantage of this type of combination lock is that it increases the difficulty of the thief to open the door lock, especially when the number of passwords is higher, the difficulty is higher. Secondly, the household no longer needs to carry the key, and can avoid the dilemma of carrying and not being able to enter. In addition, if someone wants to enter the house but does not know the password, the resident can also let him enter the room first by telling the visitor's password. The disadvantage of this kind of access control is that the combination of passwords is usually relatively simple [and does not change the stone horse often, so that the chances of being learned by the unlawful person increase, so how to develop the problem with the above-mentioned conventional structure The innovative structure with more ideal and practicality is expected to be pursued by the industry, and it is also the goal and direction of the relevant industry. In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. In view of the above objectives, after detailed design and money evaluation, the invention has finally become practical. SUMMARY OF THE INVENTION The technical problem to be solved is that the traditional door lock is the most convenient and the most convenient access control construction method, and the advantages of the farmer and the miscellaneous type are simple, easy to install, and not extra power. And when the _ key is lost, it is also convenient to find people who can unlock. It's the most obvious, the lack of work and the u. 201107577 experienced thieves can easily open almost all the door locks. In addition, the advantage of the conventional password lock 'password lock is that it increases the difficulty for the thief to open the door lock', especially the higher the number of passwords set, the higher the difficulty. Secondly, households no longer need to carry a key to avoid the embarrassment of forgetting to carry. In addition, if someone wants to enter the house but does not know the password, the resident can also let him enter the room first by telling the visitor's password. The disadvantage of this type of access control is that the combination of passwords is usually relatively simple and does not change the password frequently, increasing the chances of being informed by the wrongdoer. The technical feature of solving the problem: providing a siliary access control system with a secondary password function, mainly the one-time password authentication server (〇RS) can transmit the authentication image to the mobile phone through the multimedia message service (MMS). After opening the newsletter, you can see the original image sent by the MMS, and the new one used to regenerate the new one: the bar code (qr c〇de). After the re-creation, QRcQde needs to check the QR code image of the door-to-door machine of the RSA-authenticated client (0RC) to check whether this is the QR code of the σ, and then The image encrypted via RSA is transmitted to 〇RS wwy ' υκί5 for authentication. If the authentication is correct, the door lock can be opened via the control circuit. w Compared with the efficacy of the prior art: this creation uses -·α ^ - humanity weights. Therefore, it is impossible to enter the same group of passwords next time, and it is convenient and safe for the access control. FIELD 5 201107577 The technology, the means and the functions of the present invention will be described in detail with reference to the drawings, and it is believed that the above-mentioned objects, structures and features of the present invention can be Understanding. [Embodiment] Referring to the first to sixth figures, the present invention provides a smart access control system with a one-time password function, including: a number of mobile phones 20, each of which has a one-time password two-dimensional inside Bar code generator (0QG) application; - Door machine 21 'The door machine 21 has a camera 2 ι, the door machine 21 is an extension of the indoor unit 22; an indoor unit 22, the indoor unit 22 includes a one-time password RSA authentication client (0RC), the ORC subsystem controls the door machine 21 and the camera 211 for capturing images, and detects whether there is a QR code of the mobile phone 2, if it is detected qR c〇de The RC subsystem will start the pre-viewing process. This program will first decode the QR image, determine the message stored in the image, and then verify the content. Only the content that meets the requirements will be sent to the one-time password RSA authentication. The server (〇RS) 24 performs the processing of the step-by-step; the one-time password RSA authentication server (0RS) 24 verifies the data of the QR c〇de image of the mobile phone 20 captured by the camera 211 of the door machine 21 Only The authentication information can be legally regarded as the login request. The legality of the verification must be judged by the content, and the data contained therein can be successfully decoded, 201107577 and there is a legal and unused one-time password (〇ρτ), successfully After logging in, a new QR code image containing the legal one-time password (〇τρ) will be successfully generated. This image will be sent to the client via the MMS message 2 0 ' and will be regarded as the next authentication image; And a large door electric lock 23, which is normally controlled by the indoor unit 22, and after verification, the indoor unit 22 controls to open the door electric lock 23 to allow the visitor to enter the room. The indoor unit 22 can be separately configured from the one-time password RSA authentication server (0RS) 24 (as shown in the second figure), or can be integrated into the indoor password RSA authentication server (0RS) 24 The function of the machine 22 (as shown in Figure 1, Figure A). The one-time password RSA authentication server (0RS) 24 has a flow (see the third figure): (la) login to a new user. (lb) Capture the scene/image (2b) ° master key value message from the CCD. (3b) Store the key value to the corresponding customer. (5C) Create a new one-time password (〇TP). (lc) Wait for the one-time password rsa authentication client (0RC) message. (2c) RSA decryption. (3c) Certification. Failure (4) Send an authentication error message to the corresponding customer. If successful, (4c) transfer the login to the corresponding customer. (5c) Create a new one-time password (〇τρ). (6c) Create a new one-dimensional QR code image. (7c) Send QR c〇de to the corresponding customer by MMS. 〇海人性码 RSA certified feeding device (〇rs) 24, its main function is to verify the QR code image captured by the camera 211 201107577: the information of the s method can be legal The ground is considered a request for login. The legitimacy of the verification must be judged by the content, which contains the data that can be successfully decoded, and has a legal and unused one-time password (〇τρ). After successfully logging in, 1 will successfully generate a new one-dimensional barcode (10) c〇de) image containing the legal one-time password (0ΤΡ). This image will be s. The heart is sent to the customer and is considered the next image for certification. The one-time password RSA authentication client (0RC) has a flow (see the fourth figure): (ld) the image is taken by the camera. (2d) Establish a new thread for processing images. (3d) QR code detection (QR c〇de) detection. (4d) QR c〇de decoding. (5d) Digital message. (6d) Message length check 侃. (7d) 3d_6d is a pre-view. (8d) Connect to the feeding device. (9d) According to the response of the feeding device, send a control signal to the access control circuit. (1〇d) Terminate the thread. The one-time password RSA authentication client (0RC) is a bridge between the one-time password RSA authentication server (0RS) 24 and the one-time password two-dimensional barcode generator (〇QG), and its work is used for control. Take the video camera 2丄丄 and detect if QR c〇de is found. If a QR kernel is detected, the 0RC will start the pre-view procedure. This program first decodes the QR(3) North image, determines the message stored in the image, and then checks if the content is a string of characters 疋 616 or 617 (the RSA key with 2 〇 48 bits will be the plaintext to be encoded) Encoded as an alphanumeric string of length 6丨6 or 6丨7). Only content that meets the requirements will be sent to 〇rS for further processing. Because the server may handle multiple RC requests at the same time, the 201107577 view can slow down the burden of 〇RS. The second-order two-dimensional barcode generator (10)G) has a flow (see the fifth figure): whether it is (f) the first execution. Yes (5) Generate and store the RSA key. (3e) Encode the public key into QR(7). ^ Display the QR code in front of the camera. (5e) There is a qr code image in the MMS. Otherwise (13e) wait for the mms containing the QRcode. Yes (6e) shows the QRcode image. (7e) Decode QR c〇de. (8e) RSA decryption. (9e) Convert content. () RSA plus. (lle) QR code encoding. (i2e) Display QR code images in front of the 〇Rc camera.忒 One-time password 2D barcode generator (〇QG) application must be installed on the phone 20. First, it must first generate its own m-key, and then wrap the public key into the QR c〇de by the QR encoding mechanism. This QR code image will be sent to the 〇RS via the camera 21. After updating the public key, 〇Rs will transmit the first authenticated image to the mobile phone through MMS. Each of the 10 (10) image authentication procedures must have the following processing steps. (10) Decoding, RSA decryption, and t-material conversion RSA encryption, QR encoding, the main purpose of these processing steps are: 1. The application that receives the MMS must have a corresponding decoding key to decode the image in the MMS, so only the application that originally generated the key can Correct decoding. 2 The original qr code received by the MMS cannot be used directly for authentication, so there is no need to worry about the image being intercepted. 201107577 3 . The application must be able to obtain the International Mobile EqUipment identity number ( ιΜΕΙ ) of the corresponding mobile phone 2 The operation procedure of the aforementioned one-time password (OTP) access control system is as follows: 1 · The user uses this When inventing the access control system service, you need to register first. 'Registered information can include name, social identity ID, address, phone number, mobile device number, international mobile equipment identification code, service 丨D. 2. When the mobile phone 20 is turned on, the user installs the 〇Tp QR c〇de generator Lu (0QG). This program will generate an RSA key containing e, μ and D for this mobile phone. 3 Save the open record (Ε, Μ) to the QRc〇de image. The QR code on the phone 2 must be captured by the camera 211, and then the confidential message is transmitted to the 0RS so that the 〇RS can The authentication image is transmitted to the mobile phone 20 through the MMS. 4 • After opening the newsletter, you can see the original image of the image sent by the MMS and a button to regenerate the new QR c〇de for authentication. The QR code after re-generation needs to be read by the camera 211 of the RC to pre-view the QR image to check whether this is a valid QR code, and then transmit the image encrypted via RSA to the 〇RS for authentication. . 5. If the authentication is correct, the door lock can be opened via the control circuit. The foregoing description of the preferred embodiment of the present invention is specifically described as the technical feature 10 201107577 of the present invention; however, those skilled in the art can change the principle of the invention without the invention.
