Abstract

The invention discloses a network telephone network-based trust model construction method and relates to a security solution aiming at a voice over internet protocol (VoIP) of peer-to-peer (P2P) architecture. According to the scheme, a latest public key infrastructure (PKI) technology is adopted in the transmission process of voice data and signaling data, and bidirectional encryption during data communication is realized. In order to enhance the accessibility of the voice data in the VoIP network, a Relay Node is introduced. On the problem how to select the relay node, the calculation factors such as hardware capacities (CPU calculation capacity, memory size, disc space size and the like), online time length and forwarded data volume of the node are used in the model and deduced by related mathematical formulas, so that a service server selects a reliable user node as the forwarding node of voice information. On the problem of limiting the VoIP user authority, a trust server is introduced into the model, and the trust server can monitor the call records of the user in real time and switch on or switch off the VoIP call function of the user.

Description

technical field

[0001] The present invention is a security solution based on VoIP (Voice over Internet Protocol, IP phone) network trust mechanism. It is mainly used to optimize the voice flow in the VoIP network, help the service server in the VoIP network to select a suitable user as a voice information forwarding node, and monitor the user's call records, which belongs to the field of distributed computing software security technology. Background technique

[0002] With the rapid development of business and economy, the relationship between communication and everyone is getting closer and closer. Therefore, whether it is a network operator, an enterprise, or an individual, the requirements for communication are getting higher and higher. Many shortcomings of traditional telephones have been gradually exposed, so people began to look for a new alternative communication method. In the 1990s, IP technology was recognized by international standard organizations and manufactu...
