Joint Cipher Encoding for Secure Error Correction on Noisy Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for communicating data over unreliable channels expose error correction redundancy and are sensitive to noisy data, leading to challenges in error correction decoding due to error propagation during encryption with diffusion transformations.
Innovation Solution
Jointly performing encryption and error correction encoding, and decryption and decoding, by interleaving these operations within a memory controller engine, using modified AES-based ciphers to embed error correction encoding and decoding processes, thereby maintaining security and handling noisy data effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption with diffusion transformations is applied to data before error correction encoding, then security is improved, but error propagation occurs during encryption which worsens error correction decoding
Solution Approach 1:
The patent merges encryption and error correction encoding into a single joint operation. Instead of applying encryption then error correction separately, the system performs both operations simultaneously through a unified cipher that incorporates error correction encoding directly into the encryption process, preventing error propagation while maintaining security.
Solution Approach 2:
The patent inverts the traditional sequence by integrating error correction encoding within the encryption operation itself rather than applying it afterward. The joint cipher structure embeds error correction capabilities directly into the encryption rounds, fundamentally changing the order and integration of these operations to eliminate the harmful error propagation effect.
2Reliability
If error correction encoding is applied after encryption, then security is maintained, but error correction redundancy is exposed
Solution Approach 1:
The patent combines error correction encoding and encryption into a single integrated operation. The joint cipher produces ciphertext that simultaneously contains both encrypted data and embedded error correction redundancy, preventing the exposure of separate redundancy structures while maintaining security through the unified encryption process.
3Ease of operation
If separate encryption and error correction operations are performed, then operational simplicity is maintained, but system complexity increases
Solution Approach 1:
The patent merges two separate operations (encryption and error correction encoding) into a single joint cipher operation. This integration reduces the number of separate processing steps and components needed, thereby simplifying the overall system architecture and operation while maintaining both security and error correction capabilities.
