In one embodiment, as shown in fig. 3, a mail transmission method is provided, and the method is applied to a terminal for illustration, and includes the following steps:
step S301, receiving encrypted mail information, where the encrypted mail information includes digital signature information.
The private key information is obtained through a blockchain digital signature generation strategy.
In this embodiment, the terminal receives encrypted mail information including encrypted mail information, digital signature information, and mail certificates of the encrypted mail information through a conventional mail transmission path.
Step S302, the private key information is obtained from the blockchain according to the digital signature information of the encrypted mail information, and whether the user information of the mail sending mailbox corresponding to the private key information is identical to the user information of the preset mail sending mailbox is verified.
In this embodiment, the terminal presets the account address of the user information of the sender mailbox, sends the digital signature information of the encrypted mail information to the blockchain, and sends a query request to the blockchain through the request data in the digital signature information, and the blockchain queries the private key information corresponding to the digital signature information on the blockchain through an SM9 (GM/T0044-2016 SM9 identification cryptographic algorithm) or SM2 (elliptic curve public key cryptographic algorithm) algorithm, and feeds back the private key information to the terminal. And the terminal judges whether the account address of the user information of the mail sending mailbox corresponding to the private key information is the same as the preset account address of the user information of the mail sending mailbox according to the public key information (namely the account address of the user information of the mail sending mailbox) corresponding to the private key information.

In this embodiment, when the user information of the sending mailbox corresponding to the private key information is different from the user information of the preset sending mailbox, the terminal sends a prompt such as "mail source is unknown and risk is high" to the display end of the user of the receiving mailbox. And under the condition that the user information of the mail sending mailbox corresponding to the private key information is the same as the user information of the preset mail sending mailbox, the terminal decrypts the encrypted mail information through a decryption algorithm to obtain the mail information corresponding to the encrypted mail information. The decryption algorithm corresponds to the mail encryption algorithm, namely, the mail encrypted by the mail encryption algorithm can only be decrypted by the decryption algorithm.
Based on the scheme, whether the user information of the mail sending box corresponding to the private key information is the same as the user information of the preset mail sending box is verified, so that the problem that a mail receiving box user is attacked and destroyed due to the fact that the mail receiving box user opens risk type mails by mistake is avoided.

In this embodiment, the terminal presets a mail credential of user information of the sending mailbox, and obtains, on the blockchain, a mail credential corresponding to the private key information according to the private key information of the encrypted mail information. The terminal judges whether the mail certificate corresponding to the private key information is the same as the mail certificate of the preset user information. Under the condition that the mail certificate of the private key information is different from the mail certificate of the preset user information, the terminal sends prompt messages such as unknown mail source, high risk and the like to the display end of the user of the receiving mailbox. In the case where the mail certificate of the encrypted mail information is the same as the mail certificate of the preset user information, step S303 is performed. The present step may be executed separately from step S302, simultaneously with the execution of the step, or only any one of the steps may be executed.

In this embodiment, after the user opens the mail information, the evaluation operation may be selectively performed on the mail sending box corresponding to the mail information. And the terminal responds to the evaluation operation of the user of the receiving mailbox and acquires the evaluation value of the sending mailbox corresponding to the evaluation operation. Wherein the evaluation value can be, but is not limited to, a value corresponding to a good-bad evaluation system such as a score, a rating, etc. The terminal obtains the historical evaluation value of the mail sending box, and updates the evaluation value of the mail sending box through the evaluation value of the mail sending box by the user of the mail receiving box, so as to obtain the new evaluation value of the mail sending box. The evaluation value of the sending mailbox is updated by carrying out weighted summation operation on the historical evaluation value of the sending mailbox and the evaluation value of the sending mailbox, so that the evaluation value of the sending mailbox is updated. Or the historical evaluation value of the mailboxes can be replaced by the evaluation value of the mailboxes, so that the evaluation value of the mailboxes is updated.
The terminal presets an evaluation threshold value and judges whether the new evaluation value of the mail sending mailbox is smaller than the preset evaluation threshold value. And under the condition that the new evaluation value of the mail sending box is not smaller than a preset evaluation threshold, the terminal takes the new evaluation value as the evaluation value of the mail sending box and stores the new evaluation value into a mail sending box evaluation value database. And under the condition that the new evaluation value of the mail sending mailbox is smaller than a preset evaluation threshold value, storing account information of the terminal mail sending mailbox and user information of the mail sending mailbox into a blacklist database.
