A random number generation method and apparatus using a low-power microprocessor is provided. In the random number generation method, a low-power microprocessor determines whether external power is supplied to a random number generator. The low-power microprocessor updates an internal state of the random number generator based on a first scheme if it is determined that the external power is supplied to the random number generator. The low-power microprocessor updates the internal state of the random number generator based on a second scheme different from the first scheme if it is determined that the external power is not supplied to the random number generator.

An apparatus and method for verifying the integrity of firmware of an embedded system is provided. The apparatus for verifying the integrity of firmware of an embedded system includes a target integrity code obtainment unit for obtaining a target integrity code of firmware of the embedded system. A source integrity code obtainment unit obtains a source integrity code of source firmware. An integrity determination unit determines whether integrity of the firmware of the embedded system is maintained, by using the target integrity code and the source integrity code.

A method of generating a random number using nonvolatile memory and an apparatus for the same are provided. The method of generating a random number includes reading random number state information from nonvolatile memory when power is supplied; updating the random number state of a random number generator using the random number state information and a saving entropy source, thereby producing updated random number state information; storing the updated random number state information in the nonvolatile memory; updating a random number state of the random number generator using the updated random number state information and a generating entropy source, thereby producing a generating random number state information; and producing a random number to be used in an application program using the generating random number state information and the generating entropy source.
