Abstract:
Side-channel attacks, such as power analysis attacks, have been studied 
now for 10 years. Side-channel attacks are still one of the biggest 
security threats to real-world applications. In this talk we will look 
at side channels from a new perspective. Instead of seeing side-channels 
only as a threat to security, we will look at the constructive use of 
side-channels.
At CHESS 09, the idea of building hardware trojans using side-channels 
was first introduced. But to embed side-channels into the hardware 
design is not only lucrative for attackers who want to leak out secret 
information. Side-channels can be used to set up a hidden and encrypted 
communication channel. This can be achieved by transmitting the 
information under the noise level of the side-channel, e.g. the 
power-consumption. The information is hidden in the noise and can only 
be revealed with the knowledge of a secret. The advantage of using 
side-channels such as the power consumption to set up a communication 
channel is that no additional I/O periphery is needed and that they can 
be implemented using only a few gates.
As an example aplication for the use of side-channels we will introduce 
a watermark for integrated circuits that is based on side-channels. Such 
a watermark could be used to detect IP theft.
