Communication Device Access Control Method Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices may use access control methods that are not appropriate for servers, leading to potential communication errors and security vulnerabilities.
Innovation Solution
A communication device with a method storage and controller that requests and receives server method information, prompting users to change access control methods if more secure options are available, ensuring compatibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communication device uses a configured access control method, then the device can operate with current settings, but the method may be inappropriate for the server leading to security vulnerabilities
Solution Approach 1:
The system implements feedback by having the communication device query the server to obtain supported access control methods, then comparing these with the currently configured method. This feedback loop enables the system to identify when the configured method is inappropriate and prompt the user to change it, thereby improving security without requiring users to manually research or understand complex access control protocols.
Solution Approach 2:
The system performs preliminary action by proactively checking whether the configured access control method is appropriate before actual communication occurs. By querying the server in advance and comparing methods, the system identifies security issues beforehand and prompts users to make necessary changes, preventing potential security vulnerabilities rather than reacting to them after they occur.
2Reliability
If the communication device checks for server-supported access control methods, then compatibility and security are improved, but additional communication steps and processing time are required
Solution Approach 1:
The system applies partial action by checking only the most critical aspect of compatibility - whether the configured access control method is supported by the server. Rather than performing exhaustive verification of all possible parameters, the system focuses on the essential security check, obtaining supported methods from the server and comparing them with the configured method, thus achieving good compatibility verification with minimal time loss.
3Reliability
If the system prompts users to change access control methods, then security is enhanced, but user operation complexity increases
Solution Approach 1:
The system enables self-service by automatically obtaining the list of server-supported access control methods and performing the comparison with the configured method. This eliminates the need for users to manually research or understand which methods are appropriate, as the system autonomously identifies incompatibilities and presents clear prompts for correction, thereby enhancing security while maintaining operational simplicity.
Data Source
AI summary
A communication device includes a method storage and a controller. The method storage stores method information indicating access control methods usable by the communication device. The indicated access control methods include a configured control method that is currently set to be used by the communication device, and a candidate control method that is a candidate for the configured control method. The controller sends a request for server method information indicating one or more server control methods supported by a first server, to the first server. The controller receives a response including the server method information from the first server via the communication interface. The controller outputs first output information to prompt a user to change the configured control method to the candidate control method, in a case where a change condition is satisfied that includes a condition that the one or more server control methods include the candidate control method.
