Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure multi-party computation methods fail to provide unconditional privacy protection, as they rely on data distortion or trusted intermediaries, and are inefficient in data mining applications, while existing quantum solutions are not provably secure and require complex homomorphic encryption.
Innovation Solution
The method employs quantum entanglement of photons to enable secure data sharing and processing without revealing private information, using entangled photons with mutually unbiased measurement bases and quantum frequency conversion, allowing computations to be performed in a public channel without encryption keys or trusted parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data distortion techniques (noise adding, information blocking) are applied to protect privacy, then privacy protection level is improved, but data mining efficiency deteriorates
Solution Approach 1:
The patent replaces classical mechanical data protection methods (noise adding, information blocking) with quantum mechanical systems. Quantum entanglement and superposition enable privacy-preserving computation without distorting the underlying data, maintaining both privacy protection and data mining efficiency simultaneously.
Solution Approach 2:
The patent changes the fundamental parameter of data representation from classical bits to quantum states (qubits). This parameter change enables data to exist in superposition states, allowing multiple computational paths to be explored simultaneously while maintaining privacy through quantum entanglement, thus resolving the contradiction between privacy and efficiency.
2Reliability
If homomorphic encryption is applied to protect data-in-use, then security is improved, but system complexity increases
Solution Approach 1:
The patent replaces complex homomorphic encryption algorithms with quantum mechanical phenomena. Quantum key distribution and entanglement-based protocols provide security based on fundamental physics principles rather than computational complexity, dramatically simplifying the system architecture while maintaining or enhancing security.
Solution Approach 2:
The patent introduces quantum entangled photons as intermediaries to facilitate secure computation. These photons serve as a mediator that enables private information comparison and data processing without requiring complex encryption/decryption operations, reducing system complexity while maintaining security.
3Reliability
If quantum entanglement is used for secure computation, then unconditional security is achieved, but proof size becomes excessive for blockchain applications
Solution Approach 1:
The patent extracts only the essential verification information from quantum entanglement measurements, discarding redundant data. By using quantum random number generation and selective measurement outcomes, the system generates compact zero-knowledge proofs that maintain unconditional security while being small enough for blockchain integration.
Solution Approach 2:
The patent inverts the traditional approach by having the verifier generate challenges based on quantum randomness rather than the prover generating proofs. This inversion reduces proof size significantly while maintaining security, as the quantum-verifiable random function (QVRF) enables compact verification without requiring large proof structures.

AI summary
The present invention relates to methods for secure computation and/or communication. Entangled photons (118) are generated such that each participating party receives a series of optical pulses. Each party has private information (110, 112) which are never transmitted through public or private communication channels. Instead, each party converts their respective private information (110, 112) into measurement bases via an encryption process (114, 116) which are then applied to the entangled photons (118). After the measurement process, e.g., quantum frequency conversion (122, 124), reference indices are announced (124, 126) so that computation can be performed (128) without revealing the private information directly or indirectly.
