Interface Discovery Authentication in Name-Based Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In content-centric networks, unsolicited messages from unregistered interfaces are often dropped by nodes, leading to the loss of valid messages due to unknown source identifiers, which can result in communication disruptions and potential security threats.
Innovation Solution
An interface discovery and authentication system that generates a control message with the source identifier and local interface information, allowing the routing agent to authenticate and configure a new channel, enabling data forwarding and logging for administrative actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a node does not accept unsolicited messages from unregistered interfaces, then security is improved and attack impact is minimized, but valid messages from peer nodes are dropped causing communication disruptions
Solution Approach 1:
The system performs preliminary authentication and channel configuration actions before accepting messages. When an unregistered interface sends a message, the system initiates an authentication process and channel setup procedure in advance, rather than rejecting the message outright. This allows valid messages to be processed after verification while maintaining security against unauthorized communications.
Solution Approach 2:
The patent introduces an intermediary authentication and channel management mechanism between the unregistered interface and the message processing system. This intermediary layer verifies the legitimacy of unsolicited messages, authenticates source identifiers, and establishes communication channels before allowing message delivery. This mediator resolves the contradiction by filtering out malicious messages while permitting valid communications.
2Reliability
If all nodes are coordinated to establish communication channels among themselves, then message delivery reliability is improved, but system complexity and coordination requirements increase
Solution Approach 1:
The system implements self-service mechanisms where nodes automatically authenticate and establish channels with unregistered interfaces without requiring manual coordination. When a message arrives from an unregistered interface, the receiving node autonomously initiates authentication, verifies the source identifier, and configures the communication channel. This eliminates the need for complex pre-coordination protocols while ensuring reliable message delivery.
Solution Approach 2:
The channel configuration system is made dynamic rather than static. Instead of requiring all nodes to pre-establish fixed communication channels through complex coordination, the system dynamically creates and configures channels on-demand when messages arrive from unregistered interfaces. This dynamic approach reduces initial system complexity while maintaining message delivery reliability through automated authentication and channel setup.
3Object-affected harmful factors
If unsolicited messages are dropped without authentication, then security threats are minimized, but communication flexibility and peer node connectivity are reduced
Solution Approach 1:
The system applies partial authentication action - not all unsolicited messages are rejected, but only those that fail authentication. Messages from authenticated sources are accepted, while unauthenticated messages are dropped. This partial approach maintains security by filtering out threats while preserving communication flexibility for legitimate peer nodes that can successfully authenticate.
Solution Approach 2:
The system performs preliminary authentication checks on unsolicited messages before allowing them through. By verifying source identifiers and establishing authenticated channels in advance, the system creates a protective barrier against security threats while enabling flexible communication for legitimate messages. This preliminary anti-action filters harmful messages while preserving adaptability for authorized communications.
Data Source
AI summary
One embodiment provides an interface discovery system that facilitates interface discovery and authentication. During operation, the system receives a message from an unregistered interface via a local interface of a link adapter. The message can include a name. If the system determines that a source identifier of the message is not configured for a channel, the system generates a control message comprising the source identifier and an identifier of the local interface and sends the control message via a transport stack of the system.
