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…
Vehicle Communication using Hash Chain-based Secure Cluster
Na-Young Ahn, Dong Hoon Lee
We introduce a hash chain-based secure cluster. Here, secure cluster refers to a set of vehicles having vehicular secrecy capacity of more than a reference value. Since vehicle com…
Physical Layer Security of Autonomous Driving: Secure Vehicle-to-Vehicle Communication in A Security Cluster
Na-Young Ahn, Dong Hoon Lee
We suggest secure Vehicle-to-Vehicle communications in a secure cluster. Here, the security cluster refers to a group of vehicles having a certain level or more of secrecy capacity…
Vehicle Communication using Secrecy Capacity
Na-Young Ahn, Donghoon Lee, Seong-Jun Oh
We address secure vehicle communication using secrecy capacity. In particular, we research the relationship between secrecy capacity and various types of parameters that determine…
Privacy Protection Cache Policy on Hybrid Main Memory
Na-Young Ahn, Donghoon Lee
We firstly suggest privacy protection cache policy applying the duty to delete personal information on a hybrid main memory system. This cache policy includes generating random dat…
Duty to Delete on Non-Volatile Memory
Na-Young Ahn, Dong Hoon Lee
We firstly suggest new cache policy applying the duty to delete invalid cache data on Non-volatile Memory (NVM). This cache policy includes generating random data and overwriting t…
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…
