Embodiment Construction

[0022] figure 1 The flow chart of the Internet call method provided by the embodiment of the present invention; figure 2 A network architecture diagram applicable to the Internet calling method provided by the embodiment of the present invention. The embodiments of the present invention aim at the central server being paralyzed, or when being attacked, the communication parties will not be able to establish a call connection, resulting in reduced call reliability, and provide an Internet call method. The specific steps of the method are as follows:

[0023] Step S101, a node in the peer-to-peer network receives the user name, public key, IP address, time stamp, and first signature information of the user terminal sent by the user terminal.

[0024] Such as figure 2 As shown, when a user terminal connects to a peer-to-peer network (Peer-to-peer, P2P) for the first time, it first generates its own public key and private key, and broadcasts its own user name, public key and p...

Abstract

The embodiments of the present invention provide an Internet calling method and a device. The method includes: receiving by a node in a peer-to-peer network the user name, the public key, the IP address, the time stamp and the first signature information of a user terminal sent by the user terminal; ranking the user name, the public key, and the IP address of the user terminal according to the timestamp to obtain the recorded information; adding a random number to the recorded information and calculating the current hash value according to the recorded information with the added random number and the historical hash values; if the current hash value is less than a threshold value, sending the user name, the public key, the IP address, the timestamp of the user terminal, the random number, the current hash value, and the second signature information to other nodes in the peer-to-peer network. The embodiments of the present invention ensure the security of the user name, the public key and the IP address information of all the users in a P2P network, and improve the calling reliability.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an Internet call method and device. Background technique [0002] VoIP (Voice over Internet Protocol, VoIP) in short is to digitize the analog signal (Voice) and transmit it in real time on the IP network (IP Network) in the form of data packets (Data Packet). [0003] The basic principle of VoIP is to compress the voice data coding through the voice compression algorithm, and then process the voice data according to the Transmission Control Protocol (Transmission Control Protocol, TCP) / internet protocol (Internet Protocol, IP) standard. Packing, sending the data packets to the receiving place through the IP network, and then stringing these voice data packets together, after decompression processing, restore the original voice signal, so as to achieve the purpose of transmitting voice through the Internet. The core and key equipment of the IP...
