Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication protocols often require uniform encryption across messages, leading to inefficiencies and resource consumption due to maintaining connection state, which is not adaptable to varying security needs and can cause performance issues in resource-constrained devices.
Innovation Solution
A stateless, scalable, and lightweight communication protocol that supports multiple message formats with varying levels of security, allowing messages to be processed independently and out-of-order, using a public key infrastructure for authentication and encryption as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform encryption is applied across all messages, then security is improved, but resource consumption and device complexity increase
Solution Approach 1:
The patent applies different security levels to different messages based on their specific requirements. Some messages use encryption while others use only digital signatures or no security measures, allowing the system to provide security where needed without uniformly encrypting all messages, thus reducing overall resource consumption.
Solution Approach 2:
Instead of applying full encryption to all messages, the patent uses partial security measures appropriate to each message's needs. Some messages receive only digital signatures or basic authentication, which consumes fewer resources than full encryption, while still providing adequate security for those specific communication scenarios.
2Stability of the object's composition
If connection state is maintained across messages, then message processing coherence is improved, but device complexity and memory usage increase
Solution Approach 1:
The patent extracts the security and processing logic from a stateful connection model to a stateless message model. Each message contains all necessary information for independent processing, removing the need to maintain connection state in device memory, thus reducing device complexity while preserving processing coherence through self-contained messages.
Solution Approach 2:
The patent segments the communication into independent, self-contained messages that can be processed individually without reference to previous or future messages. Each message carries its own security context and processing instructions, eliminating the need for continuous state maintenance across the message sequence.
3Reliability
If encryption is applied to all messages, then security is improved, but processing efficiency and adaptability decrease
Solution Approach 1:
The patent applies security measures locally to each message based on its specific requirements rather than uniformly encrypting all messages. This allows critical messages to receive full encryption while less sensitive messages use lighter security measures, improving overall processing efficiency while maintaining necessary security.
Solution Approach 2:
The patent introduces dynamic security level selection where the security measure applied to each message can vary based on message type, sender, receiver, or content sensitivity. This dynamic approach allows the system to optimize processing efficiency by applying appropriate security levels rather than maximum encryption to all messages.
4Stability of the object's composition
If stateful protocol is used, then message sequence tracking is improved, but scalability and out-of-order processing capability decrease
Solution Approach 1:
The patent extracts sequence tracking from a centralized stateful protocol to individual message headers. Each message contains its own sequence information and processing instructions, allowing receivers to process messages out of order while still maintaining proper sequence tracking through the embedded message metadata, thus enabling both sequence tracking and out-of-order processing.
Solution Approach 2:
The patent makes each message self-sufficient by embedding all necessary processing information directly in the message itself, including sequence numbers, security parameters, and routing information. This allows messages to be processed independently and out of order without requiring the receiver to maintain state about the overall message sequence, improving scalability and adaptability.

AI summary
A stateless, scalable, and lightweight communication protocol may support multiple message formats that allow messages to be processed independently and with varying levels of security. When transmitting a message over a communication channel using the communication protocol, an electronic device may determine a message format for the message. The message format can be one of a plurality of message formats available for messages communicated over the communication channel. Each message format is associated with a corresponding level of security. At least one of the message formats may require message encryption. The electronic device can generate the message according to the determined format and then transmit the message to a second electronic device over the communication channel.
