Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing encryption methods are inefficient and insecure, particularly in real-time data streams, as they require decryption of encrypted files to convert to different encryption formats, exposing content to interception and are computationally intensive, and password/key management is cumbersome.
Innovation Solution
A transcoder system that uses synchronized state machines with pseudo-random number generators and multi-level context-based encryption to increase the hacker's problem space, ensuring secure conversion of encryption formats without exposing plaintext, leveraging deterministic algorithms to maintain security with minimal CPU resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional decryption and re-encryption process is used to convert encrypted files to different encryption formats, then the content can be converted to different formats, but the content is exposed to interception during the conversion process and the process is computationally intensive
Solution Approach 1:
The system performs preliminary action by pre-processing the encryption conversion through a transcoder that transforms encrypted content from one encryption format to another without requiring full decryption. This preliminary transformation maintains security throughout the process while enabling format adaptability.
Solution Approach 2:
The patent introduces an intermediary transcoder component that mediates between different encryption formats. This intermediary performs the conversion in a secure manner without exposing the plaintext content, acting as a safe bridge between encryption schemes.
2Productivity
If encryption is scaled to the end user application to minimize CPU usage, then customer experience is improved, but security management becomes more difficult when streaming to millions of users
Solution Approach 1:
The system segments the encryption management into modular components including transcoders, state machines, and key management systems. This segmentation allows distributed deployment across multiple servers and devices, making it feasible to manage security for millions of users while maintaining good customer experience.
Solution Approach 2:
The patent implements a universal transcoder architecture that can handle multiple encryption formats and serve multiple functions including encryption, decryption, and format conversion. This multi-functionality reduces the need for separate systems for different operations, simplifying security management at scale.
3Reliability
If more complex algorithms and CPU power are used to increase the hacker's problem space, then the safe time of the cipher is extended, but consumer IoT devices are left behind and become attack vectors
Solution Approach 1:
The system changes parameters by using synchronized state machines with pseudo-random number generators that can be configured with different levels of complexity. This allows the same architecture to provide extended safe time for high-security applications while maintaining compatibility with consumer IoT devices through parameter adjustment rather than algorithmic complexity.

AI summary
Information security systems and methods are presented including synchronized state machines operating with private data and tamper-evident identifiers that expand the problem space of attacks by unauthorized consumers of data in flight or rest to near infinity. A quantum cryptography-resistant distribution network for identity, trust relationship, encryption, and transcoding of valuable information is described where a priori knowledge of the hardware or software is irrelevant to the safe time for the data protected and modified as needed within a multikey encryption and data control and availability assurance domains. Due to its low compute design, the methods described within are well suited for a variety of tasks including real-time data streams such as video and audio distribution.
