Quantum-Powered Security: The Clock is Ticking on Classical Encryption

Cybersecurity faces a major challenge today: the cryptographic protocols that have long secured sensitive communications—RSA, ECC, DH-—are already vulnerable to quantum computing due to "harvest now, decrypt later" attacks. Adversaries are stockpiling encrypted data, knowing that quantum computers will break these encryption standards. This is not a future threat; it is an active risk that requires immediate action and transition to quantum-safe security solutions. Organizations that fail to prepare risk exposing critical digital assets to breaches happening now and in the near future.

Modern cybersecurity relies entirely on mathematical encryption methods. These methods have a limited lifespan. “Cryptographically-relevant” quantum computers render asymmetric cryptography obsolete by efficiently solving factorization and discrete logarithm problems using Shor’s algorithm. Even symmetric encryption, such as AES, faces threats from Grover’s algorithm, which dramatically accelerates brute-force attacks. While Post-Quantum Cryptography (PQC) is a valuable tool in the implementation of quantum-safe cybersecurity, it remains a mathematically based solution susceptible to unknown quantum computing advancements. The only truly unbreakable and “future proof” approach is quantum physics-based security, which leverages the fundamental laws of quantum mechanics and cannot be broken.

An alternative to PQC is already being deployed: entanglement-based quantum networks that use entangled pairs of photons to securely transfer information between two nodes. Quantum networks use the same fibers and telecom wavelengths already in place today, and hardware components such as lasers and single-photon detectors are commercially available. Most of this equipment operates at room temperature, making the implementation of quantum networks more feasible than many assume.

Quantum Key Distribution (QKD) is one of the practical applications of quantum networking, using quantum mechanics to create secure shared symmetric encryption keys. However, prepare-and-measure QKD (like the BB84 protocol) is just the beginning. Its single-purpose nature limits its utility compared to general-purpose entanglement-based quantum networks, which can enable not just key generation, but also direct data transmission, quantum computer interconnects, and quantum sensor networks.

To build general-purpose quantum networks, Aliro leverages protocols like BBM92, which enable entanglement-based communication. These protocols allow networks to generate secure keys and convey quantum information directly between nodes. The nodes at either end of a quantum network are typically individuals sharing secure messages, but they could also be quantum computers connected via the network to scale their capabilities. These networks support a broad spectrum of applications, including:

• Key Generation – Enables the most secure encryption keys using quantum entanglement.
• Quantum Secure Communications (QSC) – Protects sensitive data against quantum-enabled cyber threats.
• Networking of Quantum Processors – Enables future large-scale distributed quantum computing.
• Quantum Sensor Interconnectivity – Enhances precision measurement and sensing capabilities.

Whether it’s securing critical communications, interconnecting quantum computers, or laying the foundation for a quantum internet, entanglement-based quantum networking is key to unlocking many other quantum applications and capabilities. For business leaders and technologists, the message is clear: now is the time to get involved in entanglement-based quantum networking.
