First Claim
Patent Images
1. A multicast security control method based on Domain Name System DNS, comprising:
- transmitting a DNS request message to a domain name server to acquire a multicast source DNS address list of an Internet Protocol Television IPTV server;
conducting address verification on a multicast data message according to the multicast source DNS address list and a locally maintained multicast address list after the multicast data message issued by the IPTV server is received; and
conducting forwarding control on the multicast data message according to a verification result;
wherein the step of transmitting the DNS request message to the domain name server to acquire the multicast source DNS address list information of the IPTV server comprises;
allocating domain name address information of the IPTV server;
transmitting the DNS request message to the domain name server, wherein the DNS request message includes the domain name address information of the IPTV server;
receiving a response message, fed back by the domain name server, corresponding to the domain name address information of the IPTV server; and
parsing the response message to acquire the multicast source DNS address list of the IPTV server.

6. A multicast security control device based on DNS, comprising a processor and a storage device, wherein the storage device stores processor-executable programs, and the programs comprise:
-
an acquisition module, configured to transmit a DNS request message to a domain name server to acquire a multicast source DNS address list of an IPTV server; a verification module, configured to conduct address verification on a multicast data message according to the multicast source DNS address list and a locally maintained multicast address list after the multicast data message issued by the IPTV server is received; and a control module, configured to conduct forwarding control on the multicast data message according to a verification result; wherein the acquisition module comprises; a configuration unit, configured to allocate domain name address information of the IPTV server; a transmission unit, configured to transmit the DNS request message to the domain name server, wherein the DNS request message includes the domain name address information of the IPTV server; a receiving unit, configured to receive a response message, fed back by the domain name server, corresponding to the domain name address information of the IPTV server; and an acquisition unit, configured to parse the response message to acquire the multicast source DNS address list of the IPTV server. - View Dependent Claims (7, 8, 9, 10, 14, 15, 16)
