Abstract

The invention belongs to the technical field of computer network and information security, and mainly discloses a secret information transmission method under the P2P network based on the BitTorrent protocol. The secret transmission channel is established on the basis of the Handshake message transmission channel in the P2P network, relying on the established secret transmission method. channel, and embed the secret information into the BT keyword of the Handshake message for transmission by means of case-insensitive information encoding. The present invention introduces a case-insensitive information encoding method into the BT keyword of the Handshake message to implement secret communication. The secret information transmission method provided by the present invention is not only simple and efficient, but also has low implementation cost, and is more secure and reliable, and is not easy to be cracked.

Description

technical field

[0001] The invention belongs to the technical field of computer network and information security, in particular to a secret information transmission method under the P2P network based on the BitTorrent protocol. Background technique

[0002] With the rapid development of computer network communication technology, the security problem of information transmission is becoming more and more serious. Traditional encryption technology scrambles secret information and turns it into chaotic ciphertext, but it directly exposes the existence of confidential communication and easily attracts the attention of attackers. Information hiding technology is to hide secret information in approximately normal data streams, thereby hiding the existence of secret information transmission channels. Compared with traditional encryption technology, it has an extra layer of means to confuse attackers and is more secure. .

[0003] P2P network is a distributed peer-to-peer network e...
