Embodiment Construction

[0038]Spam has brought a great impact on the Internet and the majority of users. This impact is not only the time it takes for people to deal with spam and network resources, but also brings many security issues. Use content filtering to deal with spam. Through the identification of sensitive words, you can simply and directly deal with spam. However, as the privacy of the email, its content should not be leaked or obtained by any third party. Therefore, how to protect the privacy of email content and complete the filtering of sensitive words is what the email server must consider.

[0039]TEE can play the role of a black box in hardware, providing a secure computing environment isolated from untrusted environments. No external applications can access the memory space used by applications in the TEE, and neither code nor data executed in the TEE can be used at the operating system layer. Peeping, only pre-defined interfaces can operate on it. Performing operations in the TEE can ensure...

Abstract

The invention discloses a mail processing method and device, a server and a storage medium. The method is applied to the server. The method comprises the following steps: generating a first key in a trusted execution environment (TEE), wherein the first key is generated at least based on user information; generating first information based on the first key in the TEE; and issuing the first information to a terminal, so that the terminal obtains the first key by decrypting the first information, and uses the first key to encrypt a mail.

Description

Technical field[0001]This application relates to the field of network security applications, and in particular to a method, device, server and storage medium for mail processing.Background technique[0002]In related technologies, the mail filtering system can provide multiple methods of spam filtering functions to prevent accounts from being hijacked to send spam, prevent mail attacks, etc., and fully protect the security of the mail server. However, the mail filtering system will cause the leakage of mail content and cannot protect user privacy and commercial secrets.Summary of the invention[0003]In view of this, the embodiments of the present application provide a mail filtering method, device, server, and storage medium to at least solve the problem of the leakage of mail content caused by the related technical mail filtering system and the inability to guarantee user privacy and commercial secrets.[0004]The technical solutions of the embodiments of the present application are imp...
