SafeNet applies 'white box crypto' to software protection

By

A new software protection system from SafeNet is said to be safe from prying eyes.

The use of hardware dongles to protect software is less common than it was in previous decades (at least in Australia). It adds to the complexity of IT management, but it seems to have retained a niche among developers who are especially at risk from the unlicensed use of their wares.

Virtualisation is a useful technique for security researchers trying to understand how a new piece of malware works, but it (among other techniques) can also be used by those intent on breaking software protection schemes.

SafeNet has come up with a new approach that is supposed to hold fast under such scrutiny. "Our white box solution assumes that attackers have full visibility. It replaces the exposed algorithm and encryption keys with special application libraries that minimise the attack surface," said Michael Zunke, chief technology officer, software monetization solutions, SafeNet.

This way, the keys used to encrypt communication between the software and the hardware token cannot be extracted, and each application library is uniquely generated and obfuscated for each specific software vendor using SafeNet's protection system.
