Abstract: A fake base station (FBS) redirection attack method using unicast message injection in a long term evolution (LTE) wireless section and a system thereof are provided. The FBS redirection attack method includes synchronizing with a signal of a commercial base station connected with a target device being an attack target, transmitting an international mobile subscriber identity (IMSI) paging message to the target device using an IMSI of the target deice, and injecting a unicast message including a frequency of an FBS into the target device, before a base station re-access process is completed in the target device which decodes the IMSI paging message.

Abstract: Disclosed is a method for estimating a read reference voltage for a flash memory using a neural network and an apparatus therefor. According to an embodiment of the inventive concept, a method for reading a flash memory may include receiving predetermined variable values with respect to a flash memory, estimating a read reference voltage corresponding to the received variable values, using a neural network of a pre-trained learning model with respect to the variable values, and reading the flash memory, using the estimated read reference voltage. The method may further include updating the learning model of the neural network by reflecting a difference in characteristics between individual chips constituting the flash memory.
