Implementing a security server and memory devices with integrated security features that utilize cryptographic computations and access controls to validate identities, prevent unauthorized access, and manage ownership, allowing for secure communication and service access without relying on external processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current authentication methods are used for communication endpoints, then device compatibility and ease of operation are maintained, but security against counterfeit and tampering is insufficient
Solution Approach 1:
The patent replaces traditional mechanical/authentication systems with cryptographic computations. Secure memory devices perform cryptographic operations to generate authentication data, replacing physical authentication mechanisms with mathematically secure methods that resist counterfeit and tampering while maintaining system compatibility
Solution Approach 2:
The patent introduces secure memory devices as intermediaries between communication endpoints and authentication servers. These devices hold cryptographic keys and perform secure computations, acting as a trusted mediator that enhances security without requiring complex changes to the overall authentication architecture
2Reliability
If secure memory devices with cryptographic computations are implemented, then data integrity and authenticity are improved, but processing requirements and device complexity increase
Solution Approach 1:
The patent segments the authentication system into distinct functional components: secure memory devices for cryptographic computations, authentication servers for verification, and communication endpoints for operation. This segmentation allows each component to be optimized independently, managing complexity while maintaining high security standards
3Reliability
If traditional authentication methods are used, then device simplicity is maintained, but vulnerability to unauthorized access increases
Solution Approach 1:
The patent implements self-service authentication where secure memory devices automatically perform cryptographic computations and generate authentication data without requiring manual intervention. The devices self-manage their security credentials and automatically verify authenticity, protecting against unauthorized access while maintaining operational simplicity
Data Source
AI summary
A server system configured to allow a group of endpoints to share a subscription. For example, data can be stored to associate the endpoint group with at least one subscriber identifier. After receiving a validation request containing identity data generated by a memory device configured in an endpoint in the group, the server system can validate the identity data based at least in part on a secret of the memory device. In response to a determination that the identity data is valid, the system can determine that the subscriber identifier is not currently assigned to any endpoint in the group and thus assign, based on the data associating the endpoint group with the subscriber identifier, the subscriber identifier to the endpoint to cause a service offered to an account represented by the subscriber identifier to be provided to the endpoint.
