Yasmine submits the Windows BitLocker key to a central repository after she encryptions the machine. The central repository allows files to be uploaded, but not read, and is protected with access requiring special permissions. What type of solution is Yasmine's company using?

Yasmine's company has implemented a key escrow process where encryption keys are retained by the organization in case the files on the drive need to be accessed by someone with proper authority. A hardware security module (HSM) is a hardware device used to create and store encryption keys, among other encryption-related functions. Perfect forward secrecy (PFS) is a term used in encryption systems that change keys frequently to ensure that even if a key is hacked, the attacker's access to data will exist in a limited window. Private keys are part of asymmetric encryption schemes and do not reflect the full solution Yasmine's organization is using.
