Abstract

The invention provides an e-mail encryption method, a first client and a blockchain system. The method comprises the following steps: acquiring an e-mail to-be-transmitted; under the condition that afirst client establishes a communication connection with a first blockchain node, obtaining a key corresponding to the current transmission of the first client; encrypting the e-mail according to thesecret key to obtain an encrypted e-mail and an e-mail certificate; uploading the mail voucher to the first blockchain node so that the first blockchain node broadcasts the mail voucher to a second blockchain node and provides the mail voucher to a second client; and sending the encrypted email to the second client so that the second client decrypts the encrypted email through the email certificate to obtain the e-mail. On the basis of an original mail transmission path, only the mail certificate is transmitted through the blockchain, the property that the blockchain is suitable for small-volume data transmission is met, and the reconstruction, operation and maintenance cost of a mail system is reduced while mail encryption is achieved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an email encryption method, a first client and a block chain system. Background technique [0002] E-mail is one of the earliest and most important application services in the computer network. Through e-mail, people around the world can transfer messages and communicate online conveniently and quickly. Currently, e-mail communication has become a common way of communication between people.
