Abstract:
This paper studies the certificate protection mechanism in Windows operating system, it analyses the theory of the three security measures which include the private key export flag protection, the private key accession prompt protection and the password protection. A research method that uses a combination of forward analysis and reverse engineering is applied. It shows that there are security risks in the certificates in the form of software in the Windows operating system. It proposes that it can improve the certificates’ security by storing in the hardware.
