Service Integrity Adaptation for Secure Network Interchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In service-oriented architectures, existing technologies fail to effectively protect the integrity of services provided across multiple devices and networks, as they primarily focus on individual device integrity rather than service-specific integrity, which is semantically insignificant in such scenarios.
Innovation Solution
A method and system that compute and transmit service-specific integrity information across networks, using a management unit to assess and encrypt the integrity status of components, ensuring that only this information is shared, thereby adapting access rules and preventing direct access to individual device integrity from external networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service-specific integrity information is transmitted across networks, then the integrity and confidentiality of service data are improved, but the complexity of the system increases due to the need for management units and access rule adaptation mechanisms
Solution Approach 1:
A management unit is introduced as an intermediary component that collects integrity information from multiple components, processes it, and generates service-specific integrity information. This mediator abstracts the complexity from the data interchange process, allowing networks to exchange only the necessary aggregated integrity data without direct access to individual component details, thus improving reliability while managing system complexity.
2Object-affected harmful factors
If access rules are adapted based on service-specific integrity information, then the security of data interchange is improved, but the difficulty of operation increases due to the need for continuous integrity monitoring and rule adjustment
Solution Approach 1:
The system implements self-service mechanisms where the management unit automatically collects integrity information from components, evaluates it against predefined criteria, and generates updated access rules without requiring manual intervention. The components themselves provide integrity data through standardized interfaces, and the system automatically adapts access rules based on the aggregated service-specific integrity information, reducing operational complexity while maintaining high security.
3Loss of information
If individual device integrity information is protected from external access, then the confidentiality of internal system information is improved, but the measurement precision of service integrity decreases
Solution Approach 1:
The management unit merges integrity information from multiple individual components into a single service-specific integrity information item. By combining the integrity data of all components involved in a service into one aggregated representation, the system protects individual device information from external access while maintaining precise measurement of the overall service integrity. The aggregation process preserves the essential integrity characteristics needed for assessment without exposing sensitive individual component details.

AI summary
Adapting access rules for a data interchange between a first network and a second network by the second network is provided based on a service-specific integrity information item of the first network, wherein the first network processes data for carrying out a service and the service defines multiple components. A respective integrity status is transmitted for each of the components by each respective component via a communication link within the first network to a management unit of the first network. The service-specific integrity information item is computed based on each respective integrity status by the management unit. The service-specific integrity information item is transmitted by a network access point of the first network to a receiver in the second network for adapting the access rules. Access by the receiver to each respective integrity status is prevented.
