Abstract
Systems, apparatuses, and methods to mitigate effects of glitch attacks on a broadcast communication bus are provided. The voltage levels of the communication bus are repeatedly sampled to identify glitch attacks. The voltage level on the communication bus can be overdriven or overwritten to either corrupt received messages or correct received messages.
