Embodiment

[0070] In order to fully disclose the content of the present invention and illustrate the applicability of the present invention, this embodiment first introduces IGMPv3 messages before introducing the specific implementation method of the present invention.

[0071] In IGMPv3, there are two types of query messages and report messages. The query message format is shown in Table 2:

[0072] Table 2 IGMPv3 query message format

[0073]

[0074]

[0075] Among them, the fields to be used in the present invention have the following parts.

[0076] Max Response Code: The Max Response Code field specifies the maximum time allowed before sending a Response Report. The actual allowed time is called the maximum response time, and its unit is 1 / 10 second.

[0077] Group Address: When sending a normal query, the group address field must be set to 0. When sending a query for a specified group or a query for a specified group and source, it must be set to the IP group address to b...

Abstract

The invention discloses a hidden information transmission method based on IGMPv3. The router, as the sender, converts the original data into a binary bit stream, and extracts them in sequence. Response Code) for information hiding, the host as the receiver receives the query message from the router, and extracts the value N of the maximum response code field from the received query message. This method overcomes the shortcoming of low detection resistance of information hiding in IGMPv2, so as to achieve the purpose of transmitting covert information.

Description

technical field [0001] The invention belongs to the field of network communication, especially in the field of broadcast and multicast, and specifically relates to a hidden information transmission method based on IGMPv3, specifically refers to using information hiding technology to embed hidden information into IGMPv3 messages, so as to achieve transmission concealment Purpose of Information. Background technique [0002] IGMP: Internet Group Management Protocol (Internet Group Management Protocol) Internet Group Management Protocol (IGMP) is a multicast protocol in the Internet protocol family, used by IP hosts to report their group membership to any directly adjacent router. It stipulates how hosts in different network segments perform multicast communication, and the prerequisite is that the router itself must support multicast. IGMP has three versions, namely IGMP v1, v2 and v3. [0003] According to various research documents, such as "Internet Group Management Proto...
