Security control method and equipment

Abstract

The invention discloses a security control method and equipment. The method comprises the following steps that: access equipment receives registration request information coming from encoding equipment and transmits the registration request information to a video management (VM) server; and when the access equipment does not receive registration success information fed back by the VM server, the access equipment determines that the encoding equipment is an invalid access client and forbids a receiving port to forward the information coming from the encoding equipment. The security control method and the equipment can ensure that only valid monitoring business data streams appear in an internal protocol (IP) network, and therefore the utilization ratio of the bandwidth of the network can be improved to the utmost extent.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a security control method and equipment. Background technique [0002] With the continuous development of network technology and IP technology, intelligent monitoring technology based on IP and network has developed rapidly, and IP monitoring has become the mainstream of current monitoring. However, the IP network is an open network, which poses a security threat to the monitoring system; that is, devices connected to the IP network can conduct business attacks on the monitoring system, thereby causing the monitoring system to be paralyzed; or monitor the data streams of other users in the monitoring system to steal their own Data profile that you do not have permission to access. For example, an illegal user simulates an EC (Encoder, encoder) to attack a monitoring system or simulates a data stream to interfere with normal monitoring. [0003] Such as figure 1 ...

Problems solved by technology

Since the data stream is transmitted in ciphertext on the network, even if an illegal user steals the encrypted data stream, it cannot be kept confidential, that is, the data in it cannot be obtained

[0012] However, this method needs to use a complex encryption algorithm, which requires relatively high resource requirements for the monitoring system. It needs to use a special hardware encryption card to meet the access requirements of large traffic and multiple users; that is, each device in the monitoring system is required to be equipped with an encryption card. , it is difficult to achieve

In addition, data encryption is not good for multicast data
