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

[0021] like figure 1 As shown, a community management system based on digital certificates, including: terminal equipment, background server and USB key equipment, the following will introduce them one by one:

[0022] 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;

[0023] The terminal equipment can include indoor intercoms, door phones and other authorized terminal equipment; the attributes can be set as follows: individual attributes include housing numbers, department attributes include community numbers, and device serial numbers are SN numbers. 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;

[0024] The root attribute is...

Embodiment 2

[0053] 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.

[0054] A community management method based on digital certificates, comprising the steps of:

[0055] 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;

[0056] like figure 2 As shown, when the terminal device accesses the server for the first time:

[0057] 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;

[0058...

Abstract

The invention discloses a small district management system and method based on digital certificates. The small district management system comprises terminal equipment which is embedded with a digital certificate and contains multiple pieces of property information, a background server which is embedded with a digital certificate, and USB (Universal Serial Bus) key equipment. By adopting the system and the method, the access of illegal equipment and unauthorized equipment can be rejected effectively, and the invasion of hackers and the like is prevented effectively. Moreover, data are transmitted in an encrypted manner, so that a transmission way is prevented from being tampered, monitored or damaged, and the security of legal users in small districts is enhanced.

Description

[technical field] [0001] The invention relates to the field of community management, in particular to a digital certificate-based community management system and method thereof. [Background technique] [0002] 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 video communication, and the owner opens the anti-theft door through the walkie-talkie. 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 no...
