From Nintendo Switch Brew
Jump to: navigation, search

The Nintendo Switch uses Tegra's Security Engine (SE) for handling cryptographic opearations at the system's lowest level.

The SE driver is mapped to physical address 0x70012000 with a total size of 0x2000 bytes and exposes several registers for programming the Security Engine.
