Partial Authentication Code Generation for Beacon Message Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating and protecting the integrity of message contents, particularly in beacon systems, lack sufficient security and efficiency, especially for transmitters with limited resources, as they rely on weak authentication codes and insufficient cryptographic protection.
Innovation Solution
A method that calculates partial authentication codes from a repeating message content, which are then combined to form a stronger authentication code, ensuring the integrity and authenticity of messages by incrementally increasing security with each received message, even in resource-constrained transmitters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If weak authentication codes are used in beacon systems, then device complexity is reduced, but security and integrity protection are insufficient
Solution Approach 1:
The authentication code is divided into multiple partial authentication codes, each calculated from different sections of the repeating message content. This segmentation allows the system to achieve strong security without requiring a single complex authentication code, as each partial code can be computed independently using simpler cryptographic operations.
Solution Approach 2:
Multiple partial authentication codes are combined to form a complete authentication code. By merging the results of multiple simpler authentication operations, the system achieves the security strength of a complex authentication code while maintaining the simplicity of individual partial codes.
2Reliability
If cryptographic protection is enhanced, then message integrity is improved, but computational resources required increase
Solution Approach 1:
Instead of calculating a single comprehensive authentication code requiring full computational resources, the system calculates multiple partial authentication codes from different message sections. This partial action approach provides sufficient integrity protection while reducing the computational burden on resource-constrained transmitters.
Solution Approach 2:
The authentication codes are calculated continuously as messages are received, with each new message contributing additional partial authentication codes. This continuous process incrementally strengthens the authentication without requiring a single large computational burst, making it suitable for resource-constrained devices.
3Reliability
If authentication codes are calculated from repeating message content, then security is enhanced, but processing time increases
Solution Approach 1:
The repeating message content is divided into multiple sections, each processed to generate a partial authentication code. This segmentation allows parallel processing and reduces the time required compared to processing the entire message content as a single unit, while maintaining comprehensive authenticity verification.

AI summary
A method for providing messages which can be authenticated is provided. The method has a step of determining a repeating message content of the messages, a step of calculating sub-authentication codes for the messages using the repeating message content, wherein a first authentication code can be calculated for at least some of the messages from at least one part of the sub-authentication code in order to authenticate the repeating message content, and a step of providing the messages, wherein the messages contain the repeating message content and at least one respective sub-authentication code of the sub-authentication codes.
