Network Device Authentication URL Notification via DHCP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clients connecting to a network are often unaware of the necessity for authentication and may fail to access network resources without clear indication of the authentication requirement, leading to unclear access failures.
Innovation Solution
Incorporating a notification mechanism within DHCP or Router Advertisement packets to inform clients of the prerequisite URL for authentication, allowing them to perform the authentication process before attempting to communicate over the network, which includes providing a network identifier and URL in suitable packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is required before network access, then network security is improved, but client awareness of authentication requirement deteriorates
Solution Approach 1:
The patent applies preliminary action by incorporating authentication requirement information directly into DHCP or Router Advertisement packets before the client attempts network access. This ensures clients are notified of authentication requirements upfront, allowing them to complete authentication before accessing network resources, thereby resolving the contradiction between security and client awareness.
2Device complexity
If authentication process is hidden, then network complexity is reduced, but access failure clarity deteriorates
Solution Approach 1:
The patent implements feedback by providing explicit information about authentication requirements through DHCP or Router Advertisement packets. When authentication is required, clients receive clear indication through these packets, enabling them to understand why access may fail and how to proceed, thus improving access failure clarity without significantly increasing network complexity.
Data Source
AI summary
A network device includes a processor and a memory communicatively coupled to the processor. The memory stores instructions causing the processor, after execution of the instructions by the processor, to detect the presence of a client connecting to a network and send a packet to the client indicating that access to a Universal Resource Locator (URL) is a prerequisite to the client communicating over the network in response to the client connecting to the network. The packet includes the URL.
