SecureDisk
SecureDisk is an application that allows users to store data using the highest level of security available for PCs and laptops. It also enables users to export and import files securely to other machines.
SecureDisk offers the user the choice of an encryption engine. You may use AES, Triple DES, RC5, any other encryption engine or our native engine, VM.
Our encryption technology acts as a wrapper for the selected encryption engine. It provides significant features beyond those which any standard encryption engine offers.
- Our technology detects tampering without a round-trip. If an encrypted file has changed, the application will inform the user and the file will not be decrypted. We consider it to be a necessary security measure.
- Each copy of the application is unique. Unless the user decrypting the ciphertext has configured SecureDisk in exactly the same way as it was when encrypting, decryption is not possible.
- Encryption and decryption is accomplished through the use of a password and an external device, an iButton. Each user’s files are different than any others and can only be decrypted by the combination of the password and an exact replica of the iButton used to encrypt the file.
- SecureDisk creates a different ciphertext each time the plain text is encrypted. However, all of the encrypted files will decrypt perfectly. This feature greatly reduces the effectiveness of replay attacks.
There are many environments in which security based only on passwords is inadequate. This application uses an authenticating device, a smart card called an iButton.
To function correctly, the application requires the user’s password and additional information from the iButton. If either is incorrect, the application will not function.
The password is not stored in the application or the iButton. The application receives the password from the user, and sends a calculated signature to the iButton. The iButton only verifies the signature. If the signature cannot be verified, the iButton terminates the connection with the application; no further encryption or decryption is possible.
