Abstract: Provided are a random number generating device and an operating the same. The random number generating device includes a particle detector, a pulse generator, a clock counter, and a random number converter. The particle detector detects particles emitted from a radioactive isotope. The pulse generator generates pulses corresponding to the particles. The clock counter counts the number of clocks during time intervals between the pulses and generates a plurality of count values. The random number converter adjusts a clock frequency, based on a minimum value and a maximum value of the plurality of count values and converts a target count value generated depending on the adjusted clock frequency into a random number.

Abstract: An electronic device configured to perform forensic analysis on a target device includes a data extractor, an emulator, and a user data converter. The data extractor obtains, from the target device, a source file of at least one of applications installed on the target device. The data extractor obtains, from the target device, user data generated according to the least one of the applications being executed in the target device. The emulator emulates an execution of a target application installed based on the obtained source file. The user data converter converts the obtained user data having a data structure according to a database scheme of the target device into converted user data having a data structure according to a database scheme of the emulator. The emulator emulates the execution of the target application such that the target application operates using the converted user data.
