Problems solved by technology

The community door defense management system of the above method has been widely used, but in the process of use, the following problems have been found. First, the security is not high, and criminals can easily disguise illegal devices as legitimate devices to access the background server, and Carry out hacker attacks, causing disorder or paralysis of the management system of the community, and illegal activities such as burglary; second, without the authorization of the system service provider, some owners or property departments will access unauthorized equipment, which not only causes system service providers loss, but also prone to security breaches; third, it is impossible to prevent malicious reading and tampering of other devices during data transmission

Embodiment 1

[0026] Such as figure 1 As shown, a community management system based on digital certificates, including: terminal equipment, background server and USBkey equipment, the following will introduce them one by one:

[0027] Terminal device: It has multiple attribute information, including individual attribute, department attribute, device serial number and root attribute, and is embedded with its own certificate private key and background server's certificate public key;

[0028] The terminal equipment can include indoor walkie-talkies, door phones, and other authorized terminal equipment; the attribute settings can be: individual attributes include housing numbers, department attributes include community numbers, and the device serial number is the SN number. Of course, if individual attributes, department Some special numbers can also be used for attributes, etc. For example, when the terminal device is an outdoor station, other numbers can be defined;

[0029] The root attrib...

Embodiment 2

[0058] The cell management method described in this embodiment has a corresponding relationship with the cell management system in embodiment 1, so implementation 1 can be referred to.

[0059] A community management method based on digital certificates, comprising the steps of:

[0060] Store the attribute list and certificate public key of the authorized terminal device in the background server in advance, store the certificate private key of itself and the certificate public key of the background server in the terminal device;

[0061] Such as figure 2 As shown, when the terminal device accesses the server for the first time:

[0062] S1. The terminal device encrypts the data to be transmitted and transmits it to the background server through an encrypted channel. The data at least includes attribute information of the terminal device, and the attribute information includes individual attributes, department attributes, and device serial numbers and root properties;

Abstract

The invention discloses a cell management system and method based on a digital certificate. The cell management system comprises a terminal device embedded with a digital certificate and having multiple pieces of attribute information, a background server embedded with a digital certificate, and a USB key device. The cell management system can effectively reject the access of illegal device and unauthorized devices and effectively prevent hacker and other intrusion, and because of data encryption transmission, the cell management system is unlikely to tamper, monitor or destroy in the transmission path, so that the security of legitimate users of the cell is improved.

Description

[0001] This invention is a divisional application of an invention patent application with an application date of May 29, 2014, an application number of 201410233951.3, and an invention title of a digital certificate-based community management system and its method. [technical field] [0002] The invention relates to the field of community management, in particular to a digital certificate-based community management system and method thereof. [Background technique] [0003] In the existing residential quarters, each residential building in the quarter is generally equipped with anti-theft doors with door machines, and each house is equipped with terminal devices such as walkie-talkies. The terminals such as walkie-talkies are connected to the background server, and people can use IC cards or Open the anti-theft door with a password, etc., or establish a connection relationship between the door station and the walkie-talkie according to the house number and perform intercom or ...
