Abstract

The invention belongs to the technical field of block chains, and particularly relates to a mail receiving and sending system based on a block chain. Wherein the mail receiving and sending system comprises a block chain mail client and a mail block chain system, and the block chain mail client is used for receiving and sending mails, encrypting sent mail contents and decrypting the received mail contents; the mail block chain system is used for storing transaction data generated in the mail receiving and sending process through each block chain node. Through the system, the user mail plaintextdata are encrypted at the block chain mail client, so that the security of the data at the sending and transmission stages is ensured. Even if the data is intercepted by a malicious program, the ciphertext is obtained, if the ciphertext data is tampered, the check code is invalid, the verification of the block chain node is not passed, and the repudiation behavior of the user can be effectively prevented due to the characteristics of decentralized storage, non-tampering and the like of the block chain.

Description

technical field

[0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain-based mail sending and receiving system. Background technique

[0002] With the popularity of the Internet, e-mail has become one of the most important and indispensable means of communication for people, especially for various enterprises, government agencies and other organizations.

[0003] The current email system mainly consists of three parts: mail server, user agent and mail transfer protocol. The mail server provides mail transmission and storage, and generally each mail server provider has its own mail server. A user agent is a program for sending or reading mail, such as commonly used OutLook, Foxmail, etc. The mail transfer protocol refers to the agreement that the mail must abide by during the transmission process. It specifies how to exchange information between different servers (or clients). Common mail transfer protocols include SM...
