Research Of IBE Encryption Email Based On Mozilla Add-On

On the Internet, there are thousands of emails per second between each serverbetween the client and the delivery, but most of them are clearly transmitted through,so easily lead to leaks and privacy theft of trade secrets. Traditional method is to useto protect the safety of data based on digital certificate of Public Key Infrastructure(PKI), but the realization of PKI is faced with many problems, such as themanagement cost is higher, the certificate of the certificate of verification andcancellation of steps a little complicated, these problems hindered the development ofPKI in the user. And identity based encryption IBE can directly use any user identityinformation to calculate the public key, greatly simplifies the use and management ofthe public, make up is very convenient. PKI system is widely used, IBE system easyto use, a combination of both system, pseudo RSA digital certificate distributionsystem application.Mozilla Thunderbird email client platform is a kind of widely used mail client,itself the function of PKI mail encryption system. Thunderbird email client code isopen source, cross-platform and extensible function, etc. In this paper, combiningwith the results of pseudo RSA digital certificate distribution system, developed anextension on the Thunderbird makes IBE encryption technology can be applied to theMozilla platform, and will not affect the Mozilla platform itself the use of PKI emailencryption system.This extension can capture Thunderbird email client send E-mail and open themail, automatically determine whether to send encrypted mail or open the encryptedmail. When send encrypted mail, access to the recipient list, and determine whetherthe recipient has a public key certificate, if there is no public key certificate, canautomatically access to pseudo RSA digital public key certificate and imported intoThunderbird public key certificate repository, using the public key certificate toencrypt E-mail. When open the encrypted mail, can automatically judge whether thecurrent account has a private key certificate, if there is no private key certificate, canautomatically access to pseudo RSA digital private key certificate and import to theThunderbird private key certificate repository, using encrypted private key certificate for mail.In the development process, this paper deeply studied the PKI system and IBEsystem, understanding the basic framework of the Mozilla platform, analyzing theorganization structure and installation running of the extension mechanism. Thisextension uses the XPCOM component technology to invoke the pseudo RSA digitalcertificate distribution system interface to get pseudo RSA public and privatecertificate.Innovation and characteristic of this article is that IBE encryption technologywas applied to the Mozilla Thunderbird email client platform expands theThunderbird email client E-mail encryption. On E-mail encryption process, allprocesses with almost no user manual, by extending automatically in the background,the user use is very convenient. At present, the Thunderbird’s official website toprovide all of the extension, haven’t IBE encryption technology was applied to theThunderbird, so this extension has a great significance in research.
