Quantum Computing Threats to CAD Encryption: What You Need to Know
As quantum computing advances, the ability of traditional encryption methods to secure CAD files comes under serious threat. By leveraging algorithms like Shor's, a large enough quantum computer could break widely used asymmetric encryption systems, such as RSA and ECC. This poses a significant risk to engineers and designers relying on CAD solutions like SolidWorks to safeguard intellectual property.
Nobody knows the exact date of Q-Day, but NIST plans to deprecate RSA and ECC from 2030 and disallow them from 2035, so designers and manufacturers should start planning quantum-resistant strategies now.
In the context of SolidWorks users, CAD designs often represent trade secrets and proprietary knowledge. Losing control over these assets can cost an SME far more than the files themselves, especially when it operates on tight margins. Because design data stays valuable for years, the shift to new encryption that can withstand quantum attacks needs attention now, not on the day a quantum computer arrives.

How Quantum Computing Threatens CAD Encryption
Quantum computers excel at solving certain problems that classical computers find computationally infeasible. Using Shor's algorithm, they can factor large integers and compute discrete logarithms quickly, breaking encryption systems like RSA and elliptic curve cryptography, which underpin digital signatures, key exchanges and authentication processes in CAD workflows.
For CAD systems, the implications are clear: asymmetric cryptography used to verify access controls and ownership certificates could become obsolete. This is particularly worrisome for SolidWorks users sharing proprietary designs with external collaborators, manufacturers or subcontractors. Attackers can also copy encrypted files and traffic today and decrypt them later, a tactic known as "harvest now, decrypt later". Without robust protective measures, designers risk unauthorized manipulation or theft of their intellectual property.
Symmetric encryption is in a much better position. Grover's algorithm only halves the effective strength of a key, so AES-256 encryption for CAD files and SHA-256 hashes remain strong. The weak points are the public-key parts around them. This table shows where each algorithm stands:
Top Quantum-Resistant Solutions for CAD Encryption
- Post-quantum cryptography: New encryption algorithms designed to withstand quantum attacks provide an effective alternative. NIST published its first post-quantum standards in August 2024: ML-KEM (FIPS 203) and ML-DSA (FIPS 204), which are lattice-based, and SLH-DSA (FIPS 205), which is hash-based.
- Blockchain-backed protection: Integrating blockchain technology creates tamper-evident records of authorship and ownership for CAD files, adding an extra layer of evidence. Learn how blockchain interoperability in CAD systems keeps proprietary designs secure.
- Quantum key distribution: This advanced methodology uses quantum mechanics to exchange encryption keys, so any attempt to intercept them can be detected. It needs dedicated fibre or satellite links, so most companies will rely on post-quantum cryptography instead.
- Enhanced DRM/IRM technologies: Digital Rights Management (DRM) and Information Rights Management (IRM) strategies, implemented with encryption that adapts to quantum computing threats, can reinforce file security across platforms like SolidWorks.
The Role of Blockchain in Protecting CAD with SolidWorks
Blockchain technology is well suited to provide tamper-evident records for CAD files. For SolidWorks users, BORIS for SOLIDWORKS registers a hash (digital fingerprint) and a timestamp of each design version from inside SOLIDWORKS. The native files stay in your vault, and access to them is still controlled by SOLIDWORKS PDM permissions.
Smart contracts can record licensing and usage terms for CAD files shared externally, but they do not replace encryption: the files themselves still need strong encryption in storage and transit. Blockchains also rely on ECC signatures today and will need to migrate to post-quantum signatures. A SHA-256 hash and timestamp recorded before Q-Day still show that a design existed at that time, which is why registration and post-quantum encryption work best together.

Violetta Bonenkamp: Quantum Threats from a Legal and Engineering Perspective
Violetta Bonenkamp, CEO of CADChain, emphasizes that preparing CAD workflows for quantum resilience is a necessity, not an option. According to Violetta, early adoption of blockchain-integrated solutions like BORIS for SOLIDWORKS helps SMEs navigate quantum challenges without overhauling their entire process.
Her co-founder, Dirk-Jan Bonenkamp, a legal expert, further asserts that blockchain records will likely become court-admissible evidence for IP ownership disputes, which is a crucial advantage for protecting SolidWorks designs. Read more about blockchain records as legal evidence.

Common Mistakes in CAD Security Against Quantum Threats
- Relying solely on traditional encryption: Current asymmetric encryption algorithms are vulnerable to quantum breakthroughs. Transitioning to post-quantum cryptographic solutions should be prioritized.
- Failing to register designs with blockchain: Without a dated, tamper-evident record of each version, proving the authenticity and ownership of CAD files in court becomes harder.
- Ignoring collaborative risks: Sharing native files across distributed teams without clear licence terms and controlled sharing could lead to unauthorized reproduction or IP theft. Send STEP or eDrawings files where you can; see how to share CAD files without exposing IP.
- Neglecting API reliability: APIs enabling CAD file transfers must be fortified against quantum-era vulnerabilities. Learn more about AI-enhanced CAD security measures.
Preparing CAD Workflows for Quantum Resilience
- Assess vulnerabilities: Audit your existing CAD security measures to identify weaknesses exposed by quantum computing. List where RSA and ECC are used: PDM server certificates, VPN, single sign-on and code signing.
- Adopt post-quantum cryptography: Transition encryption methods used in CAD file sharing to resilient solutions defined by NIST and similar organizations, starting with hybrid key exchange where your vendors support it.
- Use blockchain-backed registration: Register each released design version with BORIS for SOLIDWORKS, which records a hash and timestamp on a blockchain as tamper-evident proof that the design existed.
- Integrate smart contracts: Record usage permissions and licence terms in smart contracts that refer to the registered versions, so they are clear and automated where payments happen on-chain. Enforcement outside the blockchain still relies on contracts and courts.
- Update training protocols: Train engineers to handle quantum-secure encryption and blockchain-relevant workflows on platforms like SolidWorks.

People Also Ask:
Could a quantum computer break Bitcoin encryption?
Yes, a quantum computer with sufficient power could theoretically break the cryptography that protects Bitcoin using algorithms like Shor’s algorithm. Bitcoin relies on ECC (Elliptic Curve Cryptography) for its signatures, which would be vulnerable to such a device. Current estimates suggest that practical quantum computers capable of breaking ECC may not emerge before 2030 or later.
How quantum computing threatens encryption?
Quantum computing threatens encryption by using algorithms that can efficiently solve mathematical problems considered infeasible for classical computers, like factoring large numbers or solving discrete logarithms. This capability could break widely-used cryptographic protocols, including RSA and ECC, compromising secure communication and data protection systems globally.
How long would it take a quantum computer to crack 256-bit encryption?
It depends on the type. For AES-256, Grover’s algorithm only halves the effective key length to about 128 bits, which would still take an impractically long time, so AES-256 is considered quantum-safe. 256-bit elliptic curve keys are different: a fault-tolerant quantum computer with thousands of logical qubits, which means millions of physical qubits, could break them with Shor’s algorithm in hours or days. Current quantum computers lack this capability and may require many years of development to reach that level.
What did Elon Musk say about quantum computing?
Elon Musk has reacted publicly to quantum computing news, for example to Google’s Willow chip announcement in December 2024.
