xPulse: Robotic Surgery Command Integrity

The Problem

Robotic surgery systems have single points of failure. A compromised controller can issue harmful commands with no independent verification layer.

Modern surgical robots like the Da Vinci system execute movements based on commands from a single controller. If that controller is compromised -- through a software bug, a cyberattack, or a hardware fault -- it can issue commands that cause patient harm. There is no independent verification that the command is safe before the robot acts.

As remote and autonomous surgery capabilities expand, the attack surface grows. A network-connected surgical robot is a safety-critical system that currently relies on single-point trust. One compromised node can override all safety checks.

The Old Way

The PRIVATE.ME Solution

XorIDA splits each surgical command across independent verification nodes. The robot only executes when threshold consensus confirms the command is valid and safe.

Every command from the surgeon's console is split into N shares and distributed to independent verification nodes. Each node independently validates the command against safety parameters, boundary checks, and patient-specific constraints. Only when K nodes return valid shares can the command be reconstructed and sent to the robot.

This creates a multi-party verification layer that no single compromised node can bypass. A malicious command injected at any single point is detected because it cannot produce valid shares at the other verification nodes.

The New Way

How It Works

Every surgical command passes through a multi-stage verification pipeline before robot execution. No single node can authorize a command alone.

Use Cases

Integration

import { verifyCommand, splitSurgicalOp } from '@private.me/surgisplit';

// Split surgical command across 3 verifiers (2-of-3)
const shares = await splitSurgicalOp(moveCommand, {
  verifiers: ['primary', 'secondary', 'safety'],
  k: 2
});

// Verify and reconstruct with threshold consensus
const result = await verifyCommand(moveCommand, {
  verifiers: ['primary', 'safety'],
  k: 2
});
// result.ok === true → safe to execute

Security Properties

Verifiable Data Protection

Every operation in this ACI produces a verifiable audit trail via xProve. HMAC-chained integrity proofs let auditors confirm that data was split, stored, and reconstructed correctly — without accessing the data itself.

Ship Proofs, Not Source

xPulse generates cryptographic proofs of correct execution without exposing proprietary algorithms. Verify integrity using zero-knowledge proofs — no source code required.
