Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network access control is used, then network services can be provided, but the system is vulnerable to unauthorized access and cybercrimes
Solution Approach 1:
The system performs preliminary authentication actions by establishing secure communication channels and verifying device identities before allowing network service access. The infrastructure device validates the user device's credentials and establishes cryptographic contexts in advance, preventing unauthorized access attempts from compromising the network.
Solution Approach 2:
The patent introduces cryptographic intermediaries including authentication contexts, cryptographic contexts, and signed tokens that mediate between the user device and infrastructure device. These intermediaries verify identities and authenticate requests without requiring direct trust between communicating parties, thereby enhancing security while maintaining manageable complexity.
2Reliability
If authentication information is transmitted securely, then unauthorized access is prevented, but communication overhead increases
Solution Approach 1:
The system performs preliminary authentication during the initial connection establishment, creating cryptographic contexts and signing tokens in advance. Once authenticated, the user device can make subsequent requests without repeating the full authentication process, reducing time loss for legitimate users while maintaining strong security.
Solution Approach 2:
The authentication mechanism dynamically adapts to different communication scenarios. The infrastructure device verifies cryptographic contexts and signed tokens with varying levels of scrutiny based on the request type and communication session state, optimizing the balance between security verification and processing speed.
3Reliability
If session-based authentication is implemented, then continuous secure communication is enabled, but session management complexity increases
Solution Approach 1:
The cryptographic context serves multiple functions simultaneously: it establishes encrypted communication channels, verifies device identities, and provides the basis for signing subsequent requests. This multi-functionality reduces session management complexity by consolidating authentication state into a single versatile data structure that the infrastructure device can verify without maintaining separate session records.

AI summary
The present disclosure discloses configuring a user device to receive an invitation link to enable the user device to receive network services from an infrastructure device; configuring the user device to receive, based on the user device activating the invitation link, seed information to be utilized by the user device to determine authentication information; configuring the user device to transmit, during an active communication session and based on determining the authentication information, a user request related to an action to be performed regarding receiving the network services, a portion of the user request being signed based on utilizing a first portion of the authentication information; and configuring the user device to perform the action regarding receiving the network services based on a verification that the communication session is currently active. Various other aspects are contemplated.
