Security

All communications between Data Vault Backup Server and your computer are transported in a 128-bit SSL (Secure Socket Layer) channel. Although all your backup files travel through a public network (internet), eavesdroppers have no knowledge of what has been exchanged.

All of your files are first zipped and encrypted with your defined encrypting key before they are sent to Data Vault backup server. To all people but you, your files stored on Data Vault backup server are no more than some garbage files with random content.

The encryption key used to encrypt your files resides only on your computer and is known only to you. It is never transmitted anywhere across the network. If this key is lost, all backup files can never be recovered. Therefore, although we have access to all files you stored on our backup server, we have no knowledge of the content of the files you stored. 

Reminder : Please make sure you write down you encryption key in a safe place where it will never be forgotten. Otherwise, you will never be able to recover your backup files.

The algorithm that we are using to encrypt your files is CBC mode AES. It is a block cipher designed by Counterpane Labs. It was also one of the five Advanced Encryption Standard (AES) finalists chosen by National Institute of Standard and Technology (NIST). It subjects to frequent public reviews but no known attack against this algorithm has been reported.

A 128-bit key size has 2128 or around 3.4 x 10³⁸ possible combination. Even if you have the world best super computer, ASCI White, SP Power3 375 MHz manufactured by IBM as of November 2000, it would take 8.77 x 10¹⁷years to test all combinations. Assuming your have the super computer, ASCI White, SP Power3 375 MHz has 8192 processors which totals a capability of 12.3 teraflops (trillions of operations/second), available to you. Also it just needs one computer operation to test a possible combination (which is already faster than what it can do). To use brute force attack (checking all combinations) on this encryption algorithm. It would take:

3.4 x 1038
-------------- seconds ~ 2.76 x 10²⁵sec 
12.3 x 1012

i.e. 876530835323573935 years or 8.77 x 10¹⁷ years

to successfully try all combinations. Let alone ASCI White cannot process as fast as what described here. You can be sure that your data stored on our server is 100% secured.

You can also restrict access to your backup files from the set of IP addresses you defined. If someone tries to access your data from an IP address not on your defined list, their access will be denied. This additional security ensures backup files is not open to all locations, even if the username and password are known.
