## Quantum Computing Impact on Cryptography
### Key Points
- Quantum computers threaten classical cryptographic algorithms like RSA and ECC due to Shor's algorithm.
- AES is vulnerable to Grover's algorithm, albeit to a lesser extent than RSA and ECC. AES-256 is more resistant than AES-128.
- Post-quantum cryptography (PQC) aims to develop algorithms resistant to quantum computer attacks.
- Quantum Key Distribution (QKD) offers secure key exchange based on quantum mechanics, but faces practical challenges.
- NIST is standardizing PQC algorithms, and organizations are exploring hybrid QKD/PQC solutions.
- The timeline for significant quantum attacks is uncertain, but proactive measures are necessary.

### Overview
Quantum computing poses a significant threat to modern cryptography. Quantum algorithms like Shor's and Grover's can break or weaken widely used encryption methods. This necessitates the development and adoption of quantum-resistant cryptographic solutions. This report provides an overview of the impact of quantum computing on existing cryptographic algorithms and explores potential solutions like post-quantum cryptography (PQC) and Quantum Key Distribution (QKD).

### Detailed Analysis
#### Vulnerabilities of Classical Cryptography
Classical cryptographic algorithms rely on mathematical problems that are difficult for classical computers to solve but are vulnerable to quantum algorithms.
| Algorithm | Vulnerability | Quantum Algorithm | Impact |
| :-------- | :------------ | :---------------- | :------------------------------------------------------------------ |
| RSA | Factoring | Shor's Algorithm | Efficient factorization of large numbers, breaking RSA encryption |
| ECC | Discrete Log | Shor's Algorithm | Efficiently solves discrete logarithm problems, breaking ECC encryption |
| AES | Brute Force | Grover's Algorithm| Reduces the search space, weakening AES security; AES-256 is stronger |
Shor's algorithm can efficiently factor large numbers, rendering RSA and ECC useless if a sufficiently powerful quantum computer is developed [http://greekcrisis.net/shors-algorithm-quantum-computers/]. Breaking RSA-2048 requires approximately 4000 qubits, and ECC-256 requires about 2500 qubits [https://ej-compute.org/index.php/compute/article/view/146].
Grover's algorithm reduces the brute-force search space for AES, weakening its security [https://ej-compute.org/index.php/compute/article/view/146]. AES-256 is more secure against quantum attacks than AES-128 or AES-192 [https://crypto.stackexchange.com/questions/6712/is-aes-256-a-post-quantum-secure-cipher-or-not].
#### Quantum Computational Resources
Breaking RSA-2048 requires around 4000 qubits and millions of gate operations, potentially achievable within the next decade [https://ej-compute.org/index.php/compute/article/view/146]. A quantum computer breaking RSA-2048 in hours could be built by 2030 for around a billion dollars [https://crypto.stackexchange.com/questions/102671/is-aes-128-quantum-safe]. IBM has a 1121-qubit 'Condor' processor, with leading platforms aiming for two-qubit gate fidelity in the range of 99.9% to 99.99% [https://methodologists.net/Exploring-the-Transformative-Advancements-in-Quantum-Computing-and-Their-Global-Impact-in-2024].
#### Post-Quantum Cryptography (PQC)
Post-quantum cryptography (PQC) involves developing cryptographic algorithms that are secure against attacks by both classical and quantum computers [https://en.wikipedia.org/wiki/Post-quantum_cryptography].
**PQC Algorithm Types**
| Algorithm Type | Examples | Characteristics |
| :------------------- | :---------------------------------------- | :--------------------------------------------------------------------------- |
| Lattice-based | CRYSTALS-Kyber, CRYSTALS-Dilithium, NTRU | Based on the hardness of lattice problems |
| Multivariate | Rainbow | Based on the difficulty of solving systems of multivariate polynomial equations |
| Hash-based | SPHINCS+ | Based on the security of cryptographic hash functions |
| Code-based | Classic McEliece | Based on the difficulty of decoding general linear codes |
| Isogeny-based | CSIDH | Based on isogenies between supersingular elliptic curves |
| Symmetric Key Quantum Resistance | AES and SNOW 3G | Post quantum resistance to known Symmetric Key Quantum resistance attacks |
PQC algorithms often require larger key sizes compared to pre-quantum algorithms [https://en.wikipedia.org/wiki/Post-quantum_cryptography].
**NIST Standardization**
NIST is conducting a Post-Quantum Cryptography Standardization Process to select PQC algorithms [https://en.wikipedia.org/wiki/Post-quantum_cryptography]. NIST has released the first three finalized post-quantum encryption standards: CRYSTALS-Kyber (ML-KEM), CRYSTALS-Dilithium (ML-DSA), and SPHINCS+ [https://www.nist.gov/news-events/news/2024/08/nist-releases-first-3-finalized-post-quantum-encryption-standards].
#### Quantum Key Distribution (QKD)
QKD offers a method for secure key exchange leveraging the principles of quantum mechanics [https://www.iosrjournals.org/iosr-jce/papers/Vol16-issue2/Version-11/A0162110109.pdf]. Eavesdropping introduces detectable anomalies due to the disturbance of the quantum system [https://en.wikipedia.org/wiki/Quantum_key_distribution].
**QKD Protocols**
| Protocol | Description |
| :------- | :---------- |
| BB84 | First QKD protocol |
| E91 | Uses entangled photons |
| COW | Coherent One Way |
Practical challenges include secret key rate, distance, size, cost, and practical security [https://arxiv.org/abs/1606.05853]. The NSA views quantum-resistant cryptography (PQC) as a more cost-effective and easily maintained solution than QKD for securing data in National Security Systems [https://www.nsa.gov/Cybersecurity/Quantum-Key-Distribution-QKD-and-Quantum-Cryptography-QC/].
#### Hybrid Approaches
Hybrid security systems integrating PQC and QKD are being explored [https://www.gsma.com/newsroom/wp-content/uploads//IG.18-Hybrid-QKD-and-PQC-security-scenarios-and-use-cases-Whitepaper-v1.0-002.pdf]. Network operators are expected to spend over $6 billion on QKD development and implementation between 2025 and 2030 [https://smartinfrastructuremagazine.com/news/quantum-key-distribution-network-operators-to-spend-6-3-billion-over-next-six-years].
#### Risk Assessment and Timelines
Quantum computing advancements are progressing, creating an urgent need to transition to quantum-safe alternatives [https://ej-compute.org/index.php/compute/article/view/146]. Cryptographic vulnerabilities may emerge within the next 5–10 years [https://ej-compute.org/index.php/compute/article/view/146].
