Abstract
An encryption device is provided, which includes a controller, a random controller, a first functional unit, and a second functional unit. The controller generates a first enable signal and a second enable signal. When at least one of the first enable signal and the second enable signal is in a first logic level, the random controller generates a first random signal and a second random signal. The first functional unit performs the corresponding operation according to the first enable signal and the first random signal. The second functional unit performs the corresponding operation according to the second enable signal and the second random signal.
