BitLocker este un feature introdus gratuit de Microsoft pe sistemele de operare Windows Vista, Windows 7 Ultimate si Windows 7 Enterprise, pentru a proteja datele de pe hard-disk. Cu ajutorul BitLocker avem posibilitatea de a cripta (encryp hdd drive) atat partitia de sistem cat si partiile de date ale hard-disk-ului, insa pentru a face acest lucru avem nevoie de Trusted Platform Module (TPM). Nu toate calculatoarele / laptop-urile au acest TPM intergrat, iar atunci cand dorim sa activam BitLocker pentru o partitie, ne apare mesajul :
A compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found. Please contact your system administrator to enable BitLocker.
Cum putem folosi BitLocker daca nu avem Trusted Platform Module (TPM).
1. Deschidem Local Group Policy Editor. (run – gpedit.msc sau tastam “gpedit.msc” in Search programs and files (Start Menu))
2. In Local Policy Group mergem la Computer Configuration > Administrative Templates > Windows Components > Bit Locker Drive Encryption > Operating System Drives si facem click-dreapta & Edit (sau dublu-click) pe Require additional authentication at startup.
3. Bifam “Enable” in fata la Require additional authentication at startup si ne asiguram ca este bifata si casuta de la Allow BitLocker without a compatible TPM.
4. Apply & OK & Restart computer.
