Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems lack effective methods to verify the authenticity and correctness of data transmitted over transmission channels, especially in safety-critical scenarios where redundancy is required.
Innovation Solution
A method involving generating first signature information based on first data and a first key, augmenting it with second data and a second key, and verifying the augmented signature information using corresponding keys at the receiver to ensure data validity, identity of the sender, and integrity of the transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission channels are provided for redundant data transmission, then reliability of communication is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple signature verification processes into a single unified verification step. The receiver verifies the augmented signature information that encompasses both first and second data signatures, thereby achieving redundancy verification without requiring separate verification procedures for each transmission channel, thus reducing system complexity while maintaining reliability
Solution Approach 2:
The augmented signature information serves multiple functions simultaneously: it verifies the authenticity of first data, verifies the authenticity of second data, and provides a unified verification mechanism for redundant transmission channels. This multi-functional approach eliminates the need for separate verification systems, reducing overall system complexity
2Reliability
If augmented signature information is generated using both first and second keys, then data authenticity verification is improved, but computational effort increases
Solution Approach 1:
The sender generates and attaches the augmented signature information to the data packets before transmission. This preliminary action ensures that the receiver can directly verify authenticity without performing additional computational steps, thereby reducing the computational energy required at the receiver end while maintaining strong authentication
Solution Approach 2:
The augmented signature information acts as a cryptographic copy that encapsulates the verification capability for both first and second data. Instead of requiring the receiver to independently verify both signatures separately, the augmented signature provides a consolidated verification mechanism that reduces computational overhead
3Reliability
If augmented signature information is transmitted with data, then data integrity is improved, but transmission data volume increases
Solution Approach 1:
The patent merges multiple signature elements into a single augmented signature information structure. Instead of transmitting separate signature data for first and second data, the augmented signature consolidates these into one compact representation, thereby maintaining data integrity verification while minimizing the increase in transmission data volume

AI summary
A sender, a receiver, and a method are provided for verifying the validity of data transmitted via a transmission channel, comprising the steps of generating first signature information on the basis of first data and a first key, augmenting the first signature information on the basis of second data and a second key. The first data is redundant with respect to the second data if the first and second data are valid. The first data or the second data and the augmented signature information is transmitted from a sender to a receiver via the transmission channel. The receiver verifies whether the augmented signature information was generated on the basis of the received data, the first key, and the second key.
