Technical info - How SilentVault Works

The SilentVault © solution creates an encrypted disk on the hard-drive. All data on this drive is stored in an encrypted format and hence prevents attacks from viruses and other ugly Internet and computer bugs. Only a user with the correct password can read the data from disk.

The solution creates a 256-bit random number, lets call it X, which is hashed to create a AES 256-bit key to encrypt/decrypt vault data. This X should be protected. To protect X, user's password is hashed to create another key and X is encrypted and stored as say X-Encrypted i.e. X is encrypted using user's password and stored.

In the Personal Edition, it is the X-Encrypted that is stored on the hard disk.

In the Professional Edition, it is the X-Encrypted that is stored on the token.

Two Barriers: In Personal Edition, anyone knowing the user id and password can open the vault.

Four Barriers: In Professional Edition, the adversary must not only know the user id and password, but must have physical access to the token and also must know the token access password.
