Embodiment 1

[0049] Such as figure 1 As shown, a blockchain-based mail sending and receiving system in an embodiment of the present invention may include a blockchain mail client and a mail blockchain system.

[0050] The blockchain mail client is used to send and receive mail, encrypt the content of the sent mail, and decrypt the content of the received mail.

[0051] The mail block chain system is used to store transaction data generated during the process of sending and receiving mail through each block chain node. The mail blockchain system includes many blockchain nodes, and its specific structure and operation mechanism can be any of various existing blockchain systems, which is not specifically limited in this embodiment.

[0052] When a user needs to send an email through the blockchain email client, the blockchain email client first encrypts the content of the email to be sent to obtain email ciphertext data. Then, the block chain mail client will construct the mail ciphertext d...

Embodiment 2

[0069] Such as Figure 5 As shown, the mail sending and receiving system in the embodiment of the present invention may include a decentralized storage system in addition to the blockchain mail client and the mail blockchain system in Embodiment 1. The decentralized storage system Including but not limited to storage systems such as IPFS, which are used to store email ciphertext data, thereby reducing the storage burden of the email blockchain system.

[0070] Such as Figure 6 As shown, when a user needs to send an email through the blockchain email client, the blockchain email client first encrypts the content of the email to be sent to obtain email ciphertext data, and sends the email The ciphertext data is sent to the decentralized storage system.

[0071] After receiving the mail ciphertext data, the decentralized storage system stores the mail ciphertext data, and sends response information to the blockchain mail client, the response information includes the mail The ...

Embodiment 3

[0091] Similar to Embodiment 2, the mail sending and receiving system in this embodiment also includes a blockchain mail client, a mail blockchain system and a decentralized storage system. However, in the second embodiment, the blockchain mail client initiates a storage request to the decentralized storage system, while in this embodiment, the blockchain node in the mail blockchain system initiates a storage request to the decentralized storage system ask.

[0092] Specifically, when a user needs to send an email through the blockchain email client, the blockchain email client first encrypts the content of the email to be sent, obtains email ciphertext data, constructs transaction data, and Send the transaction data to the email blockchain system, the transaction data includes but not limited to the email ciphertext data, sender email address, receiver email address, sending time and other data.

[0093] After the mail blockchain system receives the transaction data, it prop...

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...
