Embedded Software Anti-cloning
Software used to power embedded systems (host) is often copied, edited or changed by counterfeiters. Companies
looking for an inexpensive way to protect their host embedded software from competitors and counterfeiters can now
use the AT88SA102S as an onboard CryptoAuthentication device.
To configure embedded software for anti-cloning protection the AT88SA102S is integrated into the host. At random
intervals a challenge is sent to the CryptoAuthentication device. The response from the CryptoAuthentication is then
compared to the expected response. By providing a large number of challenges and placing those in unique areas, the
source code can be relatively well protected. This makes it extremely difficult for anyone to reverse engineer the source
code. This added difficulty will make it more cost effective for competitors and cloners to develop an entirely new
system rather than modify your existing source code. The basic operation of this security model is displayed in
Figure 3.
