Core engineering and protocols for Neurostimulation Anti-Tamper Gate.
Bidirectional BCIs do not just read brain signals; they write back into the nervous system using electrical microstimulation (used in deep brain stimulation for Parkinson's, epilepsy suppression, and sensory feedback). If a malicious hacker compromises the wireless link, they could inject electrical waveforms designed to induce grand mal seizures or permanent tissue necrosis.
BCIVault places an immutable, analog hardware safety gate between the digital communications processor and the stimulation electrode drivers. Every stimulation pulse must be cryptographically signed, and analog clamping circuits physically restrict current amplitude and pulse duration to safe neurobiological boundaries regardless of software commands.
