Table 1.

BCI security requirements vs. current solutions.

Requirement	Standard PQC	BCI need
Authentication	Separate protocols	Integrated biometric binding
Session Duration	Short-lived connections	Years of continuous operation
Forward Secrecy	Full protocol reruns	Zero-communication updates
Noise Tolerance	Error-free environments	EEG drift (15–25% variance)
Power Constraints	Server-grade hardware	Wearable devices ( mW)
