Abstract

The invention discloses a data sending method. The invention further discloses a data sending device, a data receiving method and device and equipment. When the maintenance signaling information is transmitted, the maintenance signaling information is encrypted by using the symmetric encryption algorithm, and then the encrypted data packet obtained by encryption is sent. Namely, when different decentralized network nodes in the same decentralized network transmit the maintenance signaling information, the maintenance signaling information is sent in a ciphertext form, so that the tamper-proofing capability of the maintenance signaling information is improved, namely, the security of the maintenance signaling information is improved. And meanwhile, the stability, the security and the network service quality of the decentralized network are also improved.

Description

technical field [0001] The present application relates to the technical field of data communication, and in particular to a data sending method and device, a data receiving method and device, and a device. Background technique [0002] In order to maintain the stability and normal operation of the decentralized network, each decentralized network node needs to maintain and manage each other. For example: any decentralized network node periodically sends some maintenance signaling information to other decentralized network nodes in the network to check whether other decentralized network nodes are abnormal or faulty. These maintenance signaling information are important for network stability and external Providing services is important. [0003] In the prior art, maintenance signaling information is transmitted between different decentralized network nodes through a UDP (User Datagram Protocol) protocol. Among them, the maintenance signaling information is transmitted in pl...
