Embodiment Construction

[0022] figure 1 A flowchart of a security trust processing method provided by an embodiment of the present invention; figure 2 A network architecture diagram applicable to the security trust processing method provided by the embodiment of the present invention. The specific security trust processing method steps are as follows:

[0023] Step S101 , nodes in the peer-to-peer network calculate a first hash value according to messages transmitted in the peer-to-peer network, first random numbers and historical hash values.

[0024] Such as figure 2 As shown, the first node, the second node, the third node, and the fourth node form a peer-to-peer network (Peer to Peer, P2P). equal to the number of nodes in the network. Each node is peer-to-peer in the peer-to-peer network, and their respective messages can be synchronized. Specifically, each node can be a user terminal, server, server cluster, and other devices. Each node is installed with an Internet security trust P2P pro...

Abstract

Embodiments of the present invention provide a security trust processing method and device. The method includes: a node in the peer-to-peer network calculates a first hash value according to messages transmitted in the peer-to-peer network, a first random number, and a historical hash value; if the first hash value is less than a threshold, the node calculates the first random number The number, the first hash value, and the first timestamp are sent to other nodes in the peer-to-peer network, and the first timestamp indicates the sending time of the node; the node stores the message transmitted in the peer-to-peer network. The embodiment of the present invention realizes a brand-new decentralized Internet security mechanism, and distributes public keys by means of decentralized distributed records. Rely on any third-party organization or individual to solve the problem of insufficient security of the existing Internet security trust mechanism, and provide users with safe and reliable Internet services.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a security trust processing method and device. Background technique [0002] Public key encryption, also known as asymmetric (key) encryption (public key encryption), belongs to the second-level discipline of network security under communication technology, which refers to a pair of unique keys (that is, a public key and a private key). key) encryption method. It solves the issue of key release and management, and is the core of current commercial encryption. In the public key encryption system, what is not disclosed is the private key, and what is disclosed is the public key. [0003] The public key encryption system solves this problem to a certain extent. Each user generates a pair of keys by himself: a public key and a private key. When communicating with another party, send your public key to the other party. In order to show your...
