Hardware Keystores for AI Agent Signing Workflows: A Zero-Trust MCP Enforcement Architecture

Proposes routing AI-agent cryptographic signing through hardware keystores under a zero-trust MCP architecture—directly relevant as enterprises embed autonomous agents into DevOps pipelines with software-stored secrets.

arXiv:2608.06130v1 Announce Type: new Abstract: AI agents performing cryptographic operations (signing Git commits, authenticating API calls, issuing certificates) currently store private keys in software-accessible locations: plaintext files, environment variables, or container memory. Any process with sufficient read privileges can extract the raw key material. A recent production incident demonstrated the practical severity: private keys were exfiltrated from a widely deployed framework via

Editorial Analysis

Why it matters

As enterprises deploy AI agents for automated code signing and API authentication, software-stored private keys become a high-value target; hardware-backed enforcement could materially reduce credential theft risk.

What to do

Inventory all AI-agent workflows that handle cryptographic keys and assess hardware keystore feasibility for the highest-risk signing operations.

Board brief

AI agents signing code with software-stored keys create theft risk; hardware keystores offer a concrete mitigation path.
