As quantum computing capabilities advance, federal agencies face unprecedented challenges in protecting sensitive data and communications. This article explores the emerging quantum threats and how agencies can prepare with quantum-resistant cryptography solutions.
Quantum Threats to Federal Security
Key Quantum Threats
- Shor's Algorithm: Breaks RSA and ECC encryption
- "Harvest Now, Decrypt Later": Adversaries collect encrypted data for future decryption
- PKI and Digital Signature Vulnerabilities
- Long-term classified data exposure
Understanding Quantum Computing Risks
Quantum computers leverage quantum mechanical phenomena to perform calculations exponentially faster than classical computers. This computational power poses significant risks to current cryptographic systems:
- RSA and ECC encryption vulnerability to Shor's algorithm
- Potential compromise of classified communications
- Threats to digital signatures and PKI infrastructure
- Risk to long-term data security
Mitigation Strategies
- Inventory cryptographic assets
- Adopt crypto-agile architectures
- Implement quantum-resistant algorithms
- Develop phased migration plans
- Continuous staff training on quantum security
The "Harvest Now, Decrypt Later" Threat
Adversaries may collect encrypted data now and decrypt it in the future when quantum computers become available. Sensitive information with long-term value is already at risk.

Frequently Asked Questions (FAQs)
What is quantum-resistant cryptography?
Quantum-resistant cryptography (PQC) refers to algorithms designed to withstand attacks from quantum computers, unlike traditional RSA or ECC.
When will quantum computers break current encryption?
Estimates vary, but experts predict this could happen within the next decade, making early preparation critical.
What should agencies do first?
Start with a cryptographic inventory and risk assessment, then develop a migration plan to PQC.
What is crypto-agility?
Crypto-agility is the ability to quickly switch between cryptographic algorithms as threats and standards evolve.
Are there federal mandates for quantum security?
Yes, agencies are required to begin quantum-resistant planning and follow NIST guidance.
