Final answer:
EFS encrypts the FEK using a key pair consisting of a private key and a public key, significantly increasing the security of the encrypted file.
Step-by-step explanation:
After creating a File Encryption Key (FEK) for a file, the Encrypting File System (EFS) in Windows adds a greater level of security by encrypting the FEK. EFS encrypts the FEK by creating a key pair, composed of a private key and a public key. The public key is used to encrypt the FEK, and the private key is required to decrypt it. This means that even if someone were to gain access to the encrypted file, they would not be able to decrypt the FEK and therefore the file without the corresponding private key.
After creating a File Encryption Key (FEK) for a file, the Encrypting File System (EFS) takes additional steps to enhance the security of the file. EFS instructs Windows to create a key pair consisting of a private key and a public key. It then encrypts the FEK by using the public key and stores the encrypted FEK along with the file. This process provides a greater level of security for the file.
