Abstract:
An embedded device is provided that is configured to randomize execution time of a boot process of the embedded device performed responsive to a reset signal, wherein reset release time is nondeterministic. The embedded device may include a randomizer component configured to generate a timeout signal after a random interval, wherein to randomize execution time, the embedded device is further configured to execute a first portion of a reset process, signal the randomizer component to generate the timeout signal after a first random interval, wait for the timeout signal, and execute a second portion of the reset process responsive to the timeout signal.
