| 摘要 |
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 ( 105 to 109 ). 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 ( 105 to 109 ). In this way, correct analysis of data processing being executed based on monitoring power consumption may be prevented.
