Win7之家（ afsion.com.cn）：BitLocker To Go將帶來(lái)很好的向下兼容性

 在Windows Vista中，微軟引入了BitLocker磁盤(pán)加密這個(gè)功能用于保護(hù)用戶隱私文件和數(shù)據(jù)安全。在Vista SP1中，微軟對(duì)此功能進(jìn)行了改進(jìn)，而在Windows 7中，微軟更是改進(jìn)版的BitLocker To Go。Enterprise和Ultimate版的Windows 7不僅支持本地硬盤(pán)加密，還支持可移動(dòng)磁盤(pán)的加密。此外，微軟還承諾，BitLocker To Go還會(huì)保持良好的向下兼容性，也就是說(shuō)，正如我們此前介紹的，使用BitLocker To Go加密過(guò)的U盤(pán)在Vista和XP下也可以打開(kāi)。

“BitLocker To Go的功能設(shè)計(jì)的初衷就是為了保護(hù)用戶數(shù)據(jù)安全，也就是說(shuō)，只有特定用戶才能查看加密磁盤(pán)中的內(nèi)容。并不需要特殊的硬件支持，而且，BitLocker To Go保持了很好的向下兼容性，用戶唯一需要的是BitLocker To Go Reader。”

那么，哪里下載這個(gè)BitLocker To Go Reader呢？其實(shí)，在U盤(pán)上就已經(jīng)安裝了此工具。所以，直接插上就可以了，只不過(guò)在Vista和XP上，加密過(guò)的磁盤(pán)是只讀的。

附部分原文：

With the advent of Windows Vista, Microsoft offered BitLocker Drive Encryption designed to protect customer information by encrypting machines in order to guarantee that the data was safe especially in scenarios involving stolen computers. BitLocker grew with the addition of Service Pack 1 for Windows Vista, and Windows 7 will bring the next step in the feature's evolution under the label BitLocker To Go. The Enterprise and Ultimate editions of Windows 7 will permit customers to encrypt not only local hard drives, but also removable media, with the focus on USB keys. In this regard, Microsoft has ensured that USB devices encrypted with BitLocker To Go are backward compatible with Windows XP and Windows Vista via the BitLocker To Go Reader, allowing a certain level of access to data.
