IoT Security: On-Chip Secure Deletion Scheme using ECC Modulation in IoT Appliances
Na Young Ahn, Dong Hoon Lee
NAND flash memory-based IoT devices inherently suffer from data retention issues. In IoT security, these retention issues are significant and require a robust solution for secure d…
Security of IoT Device: Perspective Forensic/Anti-Forensic Issues on Invalid Area of NAND Flash Memory
Na Young Ahn, Dong Hoon Lee
NAND flash memory-based IoT device can potentially still leave behind original personal data in an invalid area even if the data has been deleted. In this paper, we raise the foren…
Forensic Issues and Techniques to Improve Security in SSD with Flex Capacity Feature
Na Young Ahn, Dong Hoon Lee
Over-provisioning technology is typically introduced as a means to improve the performance of storage systems, such as databases. The over-provisioning area is both hidden and diff…
Countermeasure against Side-Channel Attack in Shared Memory of TrustZone
Na-Young Ahn, Dong Hoon Lee
In this paper we introduced countermeasures against side-channel attacks in the shared memory of TrustZone. We proposed zero-contention cache memory or policy between REE and TEE t…
