Current Apps: Shared Execution
01
Flat Architecture
UI, Application Logic, and Security Keys all reside in the same memory space.
02
OS Dependency
The app relies on the Android/iOS Kernel for protection. There is no secondary hardware barrier.
03
Kernel Compromise
If a Remote Access Tool (RAT) gains OS-level permissions, it gains full access to the app's secrets.
04
Factor Collapse
The attacker captures the PIN (Knowledge) and the Key (Possession) simultaneously because both are exposed.
05
Outcome: Breach
A single point of failure at the OS level results in the total compromise of the user's financial identity.
NonaShield: Isolated Execution
01
Bunker Architecture
Sensitive "Signing Logic" is moved to a Separate Execution Environment (Secure Enclave).
02
Hardware Abstraction
The OS only handles the UI. The actual security decisions happen in a Hardware-Isolated Layer.
03
OS Compromise Immunity
If the OS is infected by a virus, the Cryptographic Vault remains Dark and inaccessible to the attacker.
04
Factor Independence
The Knowledge factor (PIN) cannot compromise the Possession factor (Hardware Key) because they live in different worlds.
05
Outcome: Resilience
Even a fully compromised phone cannot perform a fraudulent transaction without the isolated hardware's approval.
