[GFW BLOG（功夫网与翻墙）] 更简单有效的对抗网络审查（Feed Over E-mail）

来源：译言

这个九月，又一个新工具加入审查规避军火库。

Feed Over E-mail (FOE) sends restricted content, in the form of RSS feeds, via email. The tool can't help a user browse censored sites or obtain large files. But its creator, Sho Ho, says that FOE could be particularly hard to block and could work in concert with other circumvention technologies. Ho, who is a researcher with the federal government's Broadcasting Board of Governors, gave a talk about FOE yesterday at Defcon, a hacker conference that takes place annually in Las Vegas.

Feed Over Email（FOE）以RSS feed形式通过email发送受限制内容。这个工具不能帮助用户浏览受审查的网站获得获取大文件。但是它的创建者，Sho ho，认为FOE很难被封锁并且可以和其他规避技术协同工作。联邦政府的研究院Ho，在Defcon（一个Las Vegas的年度黑客大会）做了报告。

There are plenty of other circumvention tools out there, but it can be hard for some people to gain access to them, Ho says. Also, the makers of such tools can get drawn into a game of cat and mouse with governments that block the access points needed to make them work.

Ho认为现在有许多规避审查的工具，但是都很难让人们接触到他们。同样，这些工具的制作者也在和封锁这些工具的访问途径的政府展开猫捉老鼠的有戏。

To use FOE, a user just needs access to an e-mail service hosted outside of a censoring country, and the FOE client. Information is sent via e-mail, which can come from servers all over the Web, making it hard for censors to spot a consistent source of censored information. Governments also usually don't block access to foreign mail services (there are some exceptions, such as North Korea).

使用FOE，用户只需要访问一个不进行审查的国家的email帐号，之后FOE客户段就可以通过email发送接收信息。由于这些信息可能来自互联网的任何地方，审查就很难连续准确定位出所有的信息源。政府通常不会封锁国外的mail服务（当然这里也有例外，比如北朝鲜）。

FOE is different from the average feed reader in that it's able to fetch content from censored sites without requiring the user to visit those sites to set up the feed. Once FOE fetches the content, it encrypts it and sends it via e-mail much like an attached file. The user's client gets decrypts the feed once it's arrived and displays it on the local machine. Ho adds that FOE should be easy for activists to set up and maintain because it uses existing infrastructure.

FOE有别于一般的可以获得不需要用户直接访问的受审查网站内容的Feed阅读器。一旦FOE抓取到这些内容，它将其加密然后以附件的形式通过email发送出去。FOE客户端接受到这些内容后，解密得到feed内容并显示在本地机器中。Ho补充道，由于基于现有架构，活跃分子（Activists）可以很容易的创建和维护FOE应用。

The version that will be released in September works on machines running Windows, Ho says, but she hopes that volunteers will help add support for other platforms, including mobile devices.

九月份释出的版本可以在Windows上运行，Ho也呼吁道，希望有志愿者可以将其移植到其他平台中，包括移动设备。
