BitLocker起源于微软2004年的[[下一代安全计算基础]]架构，其临时代号为“基石”（Cornerstone）<ref name="PdWinHEC20042">{{cite web|url = http://download.microsoft.com/download/1/8/f/18f8cee2-0b64-41f2-893d-a6f2295b40c8/TW04008_WINHEC2004.ppt|title = Next-Generation Secure Computing Base|last = Biddle|first = Peter|date = 2004|archiveurl = https://web.archive.org/web/20060827073150/http://download.microsoft.com/download/1/8/f/18f8cee2-0b64-41f2-893d-a6f2295b40c8/TW04008_WINHEC2004.ppt|archivedate = 2006-08-27|format = PPT|accessdate = 2015-01-30|publisher = [[微软|Microsoft]]|dead-url = yes}}</ref><ref name="PDC-Exclusive2">{{cite web|url = http://windowsitpro.com/article/windows-server-20082/pre-pdc-exclusive-windows-vista-product-editions-revealed-47665|title = Pre-PDC Exclusive: Windows Vista Product Editions|last = Thurrott|first = Paul|date = 2005-09-09|publisher = Penton|work = Supersite for Windows|accessdate = 2015-03-14|archive-url = https://web.archive.org/web/20150402154123/http://windowsitpro.com/article/windows-server-20082/pre-pdc-exclusive-windows-vista-product-editions-revealed-47665|archive-date = 2015-04-02|dead-url = yes}}</ref>，功能为保护设备上的信息，尤其是在设备丢失或被盗的情况下。另一个特性为“代码完整性根检测”（Code Integrity Rooting），旨在验证Microsoft Windows引导与系统文件的完整性<ref name="PdWinHEC20042" />。

当与兼容的[[可信平台模块]]（[[可信平台模块|TPM]]）结合使用时，BitLocker可以在解密受保护的[[卷 (计算)|卷]]之前验证引导和系统文件的完整性，如果验证失败，会禁止用户访问受保护的系统。<ref name="TechnicalOverview2">{{cite web|url = http://download.microsoft.com/download/5/D/6/5D6EAF2B-7DDF-476B-93DC-7CF0072878E6/secure-start_tech.doc|title = Secure Startup – Full Volume Encryption: Technical Overview|author = [[微软|Microsoft]]|date = 2005-04-22|format = DOC|accessdate = 2015-03-14|archive-date = 2017-07-01|archive-url = https://web.archive.org/web/20170701093600/http://download.microsoft.com/download/5/D/6/5D6EAF2B-7DDF-476B-93DC-7CF0072878E6/secure-start_tech.doc|dead-url = yes}}</ref><ref name="ExecutiveOverview2">{{cite web|url = http://download.microsoft.com/download/5/D/6/5D6EAF2B-7DDF-476B-93DC-7CF0072878E6/secure-start_exec.doc|title = Secure Startup – Full Volume Encryption: Executive Overview|author = [[微软|Microsoft]]|date = 2005-04-21|format = DOC|accessdate = 2015-06-09|archive-date = 2016-03-04|archive-url = https://web.archive.org/web/20160304083404/http://download.microsoft.com/download/5/D/6/5D6EAF2B-7DDF-476B-93DC-7CF0072878E6/secure-start_exec.doc|dead-url = yes}}</ref>在Windows Vista发售之前，BitLocker简称安全启动（Secure Startup）<ref name="TechnicalOverview2" />。
