Classification: CPC H  G | IPC G  H

Claim 6:
7. The device of claim 6, wherein said receiver manager is configured to raise an alarm:
if the counter is equal to said second threshold and the random signal values transmitted through said signal transmission lines are different from the updated random signal values stored during said rising edge of system clock, or
if the counter is lower than said first threshold and the random signal values transmitted through said signal transmission lines during a current system clock cycle are different from the random signal values transmitted through the signal transmission lines during the preceding system clock cycle, or
if the counter is higher than said second threshold and the random signal values transmitted through said signal transmission lines during a current system clock cycle are different from the random signal values transmitted through the signal transmission lines during the preceding system clock cycle, or
if the random signal values transmitted through said signal transmission lines change more than two times during one system clock cycle.
