ABSTRACT:
A data processor which may prevent data processing being executed from being analyzed based on the power consumption has been disclosed. A data processor (100) may include clock generating circuit (101), a random number generating circuit (102), a clock thinning-out circuit (103), and circuit resources (105to109). A clock signal (CLOCK A) may be thinned out by clock thinning out circuit (103) in correspondence to a random number generated by a random number generating circuit (102) to provide a clock signal (CLOCK C) to circuit resources (105to109). In this way, correct analysis of data processing being executed based on monitoring power consumption may be prevented.
