Quantum Computing Encryption Threats: RSA and AES Still Stand Strong
Recent advancements in quantum computing, particularly from the D-Wave announcement, have raised concerns about the longevity of traditional encryption standards such as RSA and AES. While the 22-bit RSA key factorization achieved by D-Wave’s quantum computer in October 2024 garnered attention, it remains far from threatening widely adopted algorithms like RSA-2048 or AES-256. In this article, we explore these quantum threats and explain why current encryption standards will remain resilient for years to come.
For example, IBM’s Quantum Roadmap forecasts breakthroughs in fault-tolerant quantum computing by 2030. Additionally, Google Quantum AI provides insights on the advances in qubit stability and quantum algorithms that are still far from being able to compromise encryption standards like RSA-2048. According to the Chinese Academy of Sciences, their research reinforces the prediction that stable qubits capable of breaking RSA-2048 may not be developed for at least 20 years.
Predictive Models & Scientific References
Predictive Models and Studies: Citing models like Moore’s Law for Qubits, which predicts the exponential growth in quantum computational power, can give credibility to your timeline predictions. These models suggest that while quantum advancements are rapid, reaching 20 million stable qubits for breaking RSA-2048 is unlikely within the next few decades.
References to journals like Nature and Science could strengthen your predictions. For example, Nature’s 2023 article on qubit scalability provides an academic basis for your claim that quantum advancements necessary to compromise AES-256 or RSA-2048 are decades away.
The Quantum Threat to RSA Encryption
Quantum computing has made significant strides, but it’s crucial to distinguish between current progress and future potential threats. The RSA algorithm, which relies on the difficulty of factoring large prime numbers, is particularly vulnerable to quantum attacks via Shor’s algorithm. Shor’s algorithm efficiently solves the integer factorization problem that underpins RSA’s security, creating vulnerabilities in systems dependent on RSA encryption.
In October 2024, Chinese researchers using D-Wave’s quantum computer successfully factored a 22-bit RSA key. While this result attracted significant attention, it’s far from posing an immediate threat to RSA-2048, which is widely used for secure communications. Experts estimate that factoring an RSA-2048 key would require a quantum computer equipped with approximately 20 million stable qubits:
\( N = 2^{20} \).
These qubits would need to operate continuously for around eight hours. Current systems, like D-Wave’s 5,000-qubit machine, are far from this level of capability. As a result, cracking RSA-2048 remains a theoretical possibility, but it’s still decades away from practical realization.
For more details on this breakthrough, you can review the official research report published by Wang Chao and colleagues here: Chinese Research Announcement.
Even as quantum advancements accelerate, experts agree that RSA-2048 will likely remain secure for at least the next 30 years, while RSA-4096 may resist quantum attacks for over 40 years. Transitioning to RSA-3072, as recommended by NIST, provides a more resilient alternative in preparation for future quantum capabilities.
Research on Quantum Vulnerabilities (Shor’s Algorithm and RSA)
Scientific Consensus on RSA’s Vulnerabilities
To enhance the credibility of your predictions regarding RSA, reference foundational work such as Peter Shor’s research on the factorization of prime numbers. Current consensus, including work from the Chinese Academy of Sciences and Google Quantum AI, suggests that while Shor’s algorithm poses a significant threat, practical implementation is likely decades away due to the requirement for millions of stable qubits.
Citing a 2022 study published in Physical Review Letters, which examines the theoretical number of qubits required to crack RSA-2048, strengthens this assertion. The study found that 20 million stable qubits would be necessary to break RSA-2048 using Shor’s algorithm. This would also require sustained quantum coherence for around eight hours, a feat not currently achievable by modern quantum systems. These findings align with ongoing research on Quantum Computing Encryption Threats, which continues to explore the timelines and practicalities of quantum computers’ impact on existing encryption algorithms.

Why AES-256 Remains Secure in a Quantum World
Unlike RSA, AES-256 encryption stands resilient in the face of quantum threats. Even with the use of Grover’s algorithm—a quantum algorithm that could potentially halve the effective security of AES-256—it still requires \( N = 2^{128} \) operations, a number that remains computationally prohibitive, even for future quantum systems.
To illustrate the reduction caused by Grover’s algorithm, we use the following complexity formula:
\[
N = 2^{256} \rightarrow N = 2^{128}
\]
However, 2^128 operations are still computationally prohibitive, even for future quantum systems. Furthermore, current quantum computers are nowhere near capable of exploiting this vulnerability.
Freemindtronic’s DataShielder solutions further strengthen AES-256’s resilience by incorporating segmented key encryption, with key sizes exceeding 512 bits. This segmentation method adds an additional layer of complexity to brute-force attacks, making it nearly impossible for attackers—even with quantum assistance—to capture and recombine multiple segments of the key accurately.
Current Research and Theses
Recent Theses & Academic Research
Theses and academic papers from institutions such as MIT, Stanford, and ETH Zurich often provide deep insights into post-quantum cryptography and quantum resilience. Specifically, the work of Peter Shor on Shor’s algorithm underpins much of the concern around RSA’s vulnerability to quantum computing. Mentioning Waterloo University’s Quantum-Safe Cryptography Group can also substantiate your argument on AES-256’s continued resilience when combined with techniques like segmented key encryption.
Research Supporting AES-256’s Resilience
AES-256’s Resilience in Current Research: The strength of AES-256 against Grover’s algorithm can be further supported by recent research published in Physical Review Letters and IEEE. These studies emphasize that even if quantum computers reduce the complexity of breaking AES-256 to 2^128 operations, this still remains infeasible for current quantum machines. Citing such studies will validate your claims regarding the security of AES-256 for the next 30 to 40 years, especially when using additional safeguards like segmented key encryption.
Estimating the Time to Crack AES-256 with Quantum Computers
Though AES-256 is secure for the foreseeable future, estimating the time it would take quantum computers to crack it offers valuable insights. Experts predict that a quantum system would need 20 million stable qubits to effectively execute Grover’s algorithm. Even with a reduction in security to AES-128 levels, quantum computers would still need to perform:
\[
N = 2^{128}
\]
operations. This remains computationally infeasible and poses significant challenges for quantum systems.
Currently, machines like D-Wave’s 5,000-qubit computer fall short of the qubit count required to compromise AES-256 encryption. Moreover, these qubits would need to maintain stability over extended periods to complete the necessary operations, further complicating such an attack. Consequently, AES-256 is expected to remain secure for at least the next 30 to 40 years, even with advancements in quantum computing.
Organizations should begin preparing for these future quantum threats by adopting solutions like Freemindtronic’s DataShielder, which utilizes segmented key encryption to add additional layers of protection. These segmented keys provide enhanced security, ensuring that sensitive data remains secure and future-proof against the looming quantum computing encryption threats.
Advanced Techniques to Combat Quantum Threats
To combat the emerging quantum threats, Freemindtronic has developed a patented segmented key encryption system, protected under patents in the USA, China, Europe, Spain, the UK, Japan, South Korea, and Algeria. This technique divides encryption keys into multiple segments, each of which is independently encrypted. To decrypt the data, an attacker would need to obtain and decrypt all segments of the key. Even with current quantum computers, achieving this is impossible.
For example, if you segment a 4096-bit key into four 1024-bit sections, a quantum computer would need to coordinate across significantly more qubits, thereby complicating the decryption process. This method effectively future-proofs encryption systems against quantum advancements and significantly strengthens the security of AES-256 CBC encryption.
The Quantum Roadmap: What’s Next for RSA and AES?
The October 2024 D-Wave factorization of a 22-bit RSA key showcases the potential of quantum computing. However, cracking RSA-2048 requires exponential advancements in quantum capabilities, far beyond today’s systems. Experts estimate that breaking RSA-2048 could take at least 30 years, while RSA-4096 may resist attacks for over 40 years.
To safeguard encryption during this period, NIST recommends transitioning to RSA-3072, which offers better quantum resistance than RSA-2048. Additionally, adopting post-quantum cryptography (PQC) solutions, especially for critical infrastructures, will ensure systems remain resilient as quantum technologies advance. For AES-256, it’s estimated that 295 million qubits would be required to crack it, reaffirming its continued security. With innovations like segmented key encryption, AES-256 will likely remain highly resistant to quantum computing for decades.
