Abstract: Provided is a method of protecting an application from reverse engineering. The method includes registering, in an electronic device, a handler capable of being called as a preset fault is generated in the application, after the handler is registered, executing a protection code for generating the preset fault in the application, determining whether an environment where the application is executed is an abnormal environment, based on whether the handler has been called as the protection code is executed, and performing an operation for protecting the application, based on a result of the determination.

Abstract: Disclosed is an electronic device. An electronic device according to various embodiments comprises: a housing elongated between a first end portion and a second end portion; a resonant circuit having a coil placed inside the housing; a wireless communication circuit placed inside the housing; a rectifier for rectifying, to a direct-current power, an alternating-current power which is received via the resonant circuit; a battery which is charged by using the direct-current power; a switch for selectively connecting between the rectifier and the battery; a voltage detector which is set to detect the voltage value of the direct-current power and transmit, on the basis of the detected voltage value, a control signal for turning the switch on and off to the switch and the wireless communication circuit, wherein, when an interval of time between the control signals to be sequentially received from the voltage detector is the same or less than a predetermined value, the wireless communication circuit can be set to ignore at least one control signal to be received additionally after the sequentially received control signals. Other various embodiments can be provided.
