Migrating legacy ERP systems to post-quantum cryptography standards for supply chain data protection

ERP systems are the central nervous systems of the global supply chain, housing intellectual property, vendor contracts, and sensitive financial data. However, the cryptographic foundations of these systems—most of which rely on RSA and Elliptic Curve Cryptography (ECC)—are fundamentally threatened by the advent of quantum computing.

For the enterprise, the risk is not just a future “Q-Day.” It is the “Harvest Now, Decrypt Later” (HNDL) strategy currently employed by state actors who are intercepting encrypted ERP traffic today to decrypt it once cryptographically relevant quantum computers (CRQC) emerge. Migrating legacy ERPs to Post-Quantum Cryptography (PQC) is a mission-critical imperative that requires more than a simple software patch; it requires a structural rethinking of how data is stored, transmitted, and authenticated across the supply chain.

1. The Vulnerable Nexus: Why ERPs are Targets

An ERP system is the ultimate “honeypot.” It aggregates data from procurement, manufacturing, and logistics into a single … Read More
