IoT Security: On-Chip Secure Deletion Scheme using ECC Modulation in IoT Appliances. (arXiv:2308.05225v1 [cs.CR])

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 deletion. Secure deletion methods can be categorized
into off-chip and on-chip schemes. Off-chip secure deletion schemes, based on
block-level erasure operations, are unable to perform real-time trim
operations. Consequently, they are vulnerable to hacking threats. On the other
hand, on-chip secure deletion schemes enable real-time trim operations by
performing deletion on a page-by-page basis. …
