autogen - 💡(How to fix) Fix Cryptographic governance layer for AutoGen distributed agent runtime [22 comments, 5 participants]

Fix Plan

To integrate the Agent Passport System, follow these steps:

• Step 1: Generate Ed25519 passports for each agent:
  • Use a library like ed25519 to generate key pairs.
  • Store the private key securely and share the public key with other agents.
• Step 2: Implement signed delegation chains:
  • Use a library like json-web-token to create and verify JSON Web Tokens (JWTs).
  • Include the agent's identity, scope, and expiration time in the JWT payload.
• Step 3: Validate identity and scope using the ProxyGateway:
  • Verify the agent's identity by checking the Ed25519 signature.
  • Check the delegation chain to ensure the agent has the required scope.
• Step 4: Generate signed ActionReceipts:
  • Use a library like ed25519 to create a digital signature for each action.
  • Include the action details and agent identity in the signature payload.

Example code (Node.js):

const ed25519 = require('ed25519');
const jwt = require('jsonwebtoken');

// Generate Ed25519 key pair
const keyPair = ed25519.generateKeyPair();

// Create a JWT with delegation chain
const token = jwt.sign({
  agentId: 'agent-a',
  scope: ['read', 'write'],
  exp: Math.floor(Date.now() / 1000) + 3600
}, keyPair.privateKey, { algorithm: 'ES256' });

// Verify token and delegation chain
jwt.verify(token, keyPair.publicKey, { algorithms: ['ES256'] }, (err, decoded) => {
  if (err) {
    console.error(err);
  } else {
    console.log(decoded);
  }
});

// Generate signed ActionReceipt
const actionReceipt = ed25519.sign({
  action: 'read',
  agentId: 'agent-a'
}, keyPair.privateKey);

Verification

To verify the fix, test the following scenarios:

• Agent A sends a message to Agent B with a valid Ed25519 passport and delegation chain.
• Agent A sends a message to Agent B with an invalid or expired Ed25519 passport.
• Agent A sends a message to Agent B with a valid Ed25519 passport but insufficient scope.

Extra Tips

• Use a secure random number generator to generate Ed25519 key pairs.
• Implement a revocation mechanism to handle compromised or expired passports.
• Monitor and analyze ActionReceipts to detect potential security issues.
