Seoul National University has developed hardware security technology that can hide and display encryption keys on demand using 3D flash memory

According to foreign media reports, the School of Engineering of Seoul National University announced that its research team has developed a new hardware security technology based on commercial 3D NAND flash memory (V-NAND flash memory).

This technology, called Concealable PUF, retains the core advantages of traditional PUF – unclonability and randomness, but adds a new feature: the ability to hide security keys and display them only when needed. This marks the first time in the world that such a feature has been implemented on V-NAND flash memory.
