Preventing Quantum Attacks on RSA and AES Encryption
How PrivID Could be the Missing Key
Chinese scientists claim to have used quantum computers to crack military-grade encryption, specifically targeting RSA and AES algorithms. That is according to recent reports. This underscores a growing reality: quantum computing is no longer a distant possibility but an imminent challenge for traditional encryption methods.
This breakthrough poses a "real and substantial threat" to the “tried and true [and dated]” encryption standards, particularly those underpinning much of today’s digital security. But there are solutions. Innovative technologies like PrivID have been positioned to mitigate these emerging quantum risks for some time, ensuring data security in the face of these forms of attack.
The Quantum Threat to RSA and AES
RSA and AES are widely regarded as pillars of cryptographic security. RSA relies on the difficulty of factoring large prime numbers, while AES uses complex substitution-permutation networks to encrypt data. Both methods are strong, but not unbreakable.
Quantum computers, with their ability to process immense calculations simultaneously, have changed the game. Shor’s and Grover’s algorithms make quick work of RSA’s prime factorisation and reduce the search space for AES keys. This means quantum computers render current encryption methods obsolete, endangering everything from military communications to financial transactions.
How PrivID Works Against Quantum Attacks
PrivID’s advanced solutions are designed to meet not just current cybersecurity challenges but future threats like quantum computing. Here's how:
1. Post-Quantum Cryptography Integration
PrivID already incorporates post-quantum cryptographic algorithms that are resistant to quantum attacks. These algorithms are based on mathematical problems that remain computationally infeasible even for quantum computers, such as lattice-based cryptography, hash-based signatures, and multivariate polynomial problems.
By transitioning away from RSA and AES to quantum-resistant encryption, PrivID ensures that sensitive data remains secure even as quantum capabilities advance.
2. Zero-Knowledge Proofs (ZKP)
Zero-knowledge proofs, a cornerstone of PrivID’s technology, enable data verification without revealing the underlying data itself. Unlike traditional encryption, which can be targeted for decryption, ZKPs create a system where there’s nothing for attackers to “decrypt”, when combined with FHE. This drastically reduces the attack surface for quantum or classical adversaries.
3. Fully Homomorphic Encryption (FHE)
FHE allows data to be processed while encrypted, eliminating the need to decrypt sensitive information during operations. This provides a significant advantage against quantum threats: even if a quantum computer could intercept the data, it would only encounter ciphertext, not plain text or actionable information.
4. Granular Access Control and Segmentation
PrivID’s architecture ensures that data is segmented and accessible only on a strict need-to-know basis. Even if one segment were compromised (a highly unlikely scenario), the overall system remains secure. This principle limits the potential damage of any [quantum-enabled] breach.

Practical Benefits for Organisations
Adopting PrivID’s quantum-secure solutions isn’t just about staying ahead of the curve; it’s about future-proofing operations. For organisations managing critical infrastructure, government secrets, or financial data, the stakes couldn’t be higher.
By implementing PrivID, organisations can:
Ensure long-term data confidentiality, even against future quantum advancements.
Avoid costly retrofits once quantum-safe cryptography becomes mandatory.
Demonstrate leadership in adopting cutting-edge cybersecurity measures, enhancing trust with customers and stakeholders.
A Post-Quantum World
The Chinese breakthrough is a wake-up call. While it may still be years before quantum computers become widely available, the time to act is now. Organisations need encryption solutions designed for a quantum future to prevent playing catch-up when the threat materialises.
PrivID’s commitment to leveraging post-quantum cryptography, combined with innovative techniques like ZKP and FHE, positions it as a strong solution in this and the upcoming era of computations. With PrivID, the transition to a quantum-secure world can be seamless, efficient, and effective.
Final Thoughts
Quantum computing represents both an opportunity and a challenge. While its potential to revolutionise industries is undeniable, its implications for cybersecurity cannot be ignored. RSA and AES, once seen as impenetrable, aren’t. The need for quantum-resistant solutions like PrivID has never been more needed and necessary.
In an age where the rules of cryptography are being rewritten, PrivID is the author that can make your organisation remain secure, compliant, and prepared for whatever comes. The future may be quantum, but with PrivID, so is your defence.
