Abstract: Disclosed herein are a garbage collection method and apparatus. The garbage collection method includes when an area dynamically allocated through a malloc( ) function or a new operator of a standard C library is deallocated through a free( ) function or a delete operator, inserting the deallocated area into a quarantine list, recording a base address and an end address of each of areas inserted into the quarantine list in a CSR_quarantined_chunks register, finding a physical address of a memory page used by a processor and searching data in the memory page for a value included in a quarantined area of the CSR_quarantined_chunks register, when a value included in the quarantined area is not present, setting a state flag bit of the register to 0, and deleting an area which the state flag bit is 0 from the quarantine list, and inserting the area into a free list.

Abstract: Disclosed herein are a fuzzing preprocessing apparatus and method for automating smart network fuzzing. The fuzzing preprocessing method includes collecting communication message samples that are sent by a fuzzing target client to a fuzzing target system, comparing the communication message samples with each other, and then identifying sizes and types of fields of a fuzzing target protocol, determining a property of a protocol field value with reference to ASCII code, determining a coverage of a user field based on a response message to a test communication message that has been sent to the fuzzing target system, and storing a fuzzing protocol data model having a field number, a field type, a field size, a field value property, and a field value of the fuzzing target protocol, as elements.

Abstract: An apparatus and method for collecting the radio frequency (RF) feature of a wireless device in a wireless communication apparatus are disclosed herein. The RF feature extraction unit adds a tag having a unique value to a received radio signal, and extracts RF feature information from the radio signal. The MAC information extraction unit extracts the source MAC address and tag information of a MAC protocol frame from the received radio signal, and then removes the added tag. The tag comparison unit selects an source MAC address and RF feature information, when the tags have the same value, from the RF feature information and tag information from the RF feature extraction unit and the source MAC address and tag information from the MAC information extraction unit. The RF feature storage unit stores the selected source MAC address and RF feature information.
