Controlled Message Encryption With Rights-Based Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems lack robust privacy protection, allowing unauthorized access, data breaches, and vulnerability to quantum computing, with insufficient control over message disposition and actions, and fail to authenticate senders effectively.
Innovation Solution
Implementing Secure Controlled Communications (SCC) using asymmetric and symmetric encryption, digital signatures, and message rights to ensure end-to-end encryption, authenticate senders, control message disposition, and restrict actions, while being quantum-safe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end-to-end encryption with asymmetric and symmetric encryption is implemented, then information confidentiality and security are improved, but device complexity and computational overhead increase
Solution Approach 1:
The encryption system is segmented into two distinct parts: asymmetric encryption for key exchange and symmetric encryption for data encryption. This segmentation allows each encryption type to be optimized for its specific purpose, improving overall security while managing complexity through functional separation.
Solution Approach 2:
Asymmetric encryption acts as an intermediary mechanism that enables secure key exchange between parties without requiring them to share secret keys directly. This intermediary layer protects the symmetric encryption keys during transmission, resolving the complexity of secure key distribution.
2Reliability
If digital signatures are used to authenticate senders, then sender authentication and data integrity are improved, but computational overhead and processing time increase
Solution Approach 1:
Digital signatures are generated and attached to messages in advance during the encryption process, rather than being verified separately. This preliminary action integrates authentication into the existing encryption workflow, minimizing additional processing time while maintaining strong sender verification.
3Reliability
If message rights control is implemented to restrict actions on information, then information security and authorization control are improved, but system complexity and operational overhead increase
Solution Approach 1:
Message rights and authorization controls are applied locally to individual messages or message groups rather than requiring a centralized rights management system. Each encrypted message carries its own access control parameters, allowing fine-grained control without complex global authorization infrastructure.
4Reliability
If quantum-safe encryption is implemented, then long-term security against quantum computing threats is improved, but computational requirements and processing overhead increase
Solution Approach 1:
The system uses post-quantum cryptographic algorithms that rely on different mathematical problems (such as lattice-based cryptography) rather than traditional factoring or discrete logarithm problems. This parameter change in the cryptographic foundation provides quantum resistance while maintaining computational efficiency through optimized algorithm implementations.

AI summary
A system for secure controlled communications between entities is described that incorporates: confidentiality, sender authentication, data integrity, malware resistance, and author defined rights. A novel mechanism is described where the system creates symmetric encryption parameters (“SEPs”) for each message and independently encrypts message: metadata, rights, body, and attachments with symmetric encryption. The SEPs themselves are encrypted with asymmetric encryption, using the recipient's public asymmetric encryption key. Only intended recipients can decrypt the encrypted SEPs with their corresponding private asymmetric decryption key and use these SEPs to decrypt encrypted: metadata, rights, body, and attachments. The system also generates a digital signature of these SEPs, signed by the sender with their private asymmetric signature key. This allows any recipient to authenticate the sender by verifying the digital signature using the sender's public asymmetric signature key. Actions taken on a message and its disposition are controlled by message rights set by the author.
