Communication Access Control Gateway for Flexible Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication control methods fail to securely allow access to user devices from different access sources, such as acquaintances or service programs, as they do not provide flexible access control and service adaptation based on the access source.
Innovation Solution
A communication control apparatus and method that establish a virtual communication channel, authenticate access requests, and refer to access control policies to allow or deny access, enabling safe access to user devices via a network by using a gateway that manages access control lists and authenticates clients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relay server is used to enable Internet access to user devices, then connectivity is improved, but access control flexibility deteriorates
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the Internet and user devices. This gateway maintains the tunneling connection for reliable connectivity while implementing sophisticated access control mechanisms including access control lists (ACLs), authentication units, and service information management. The gateway acts as a mediator that can authenticate multiple different access sources and selectively forward requests based on predefined policies, thus resolving the contradiction between maintaining connectivity and enabling flexible access control.
2Reliability
If access control is strictly enforced for safety, then security is improved, but service adaptability deteriorates
Solution Approach 1:
The patent implements dynamic access control where the gateway can adapt service provision based on the authenticated access source. The access control unit references access control lists to dynamically determine whether to allow access and what services to provide. Different access sources (owners, acquaintances, service programs) can be granted different levels of access and service types, enabling the system to maintain strict security while adapting services to the specific needs of each access source.
Solution Approach 2:
The system changes access parameters dynamically based on authentication results. The gateway authenticates access sources and then modifies access control parameters (allowed services, access permissions) according to the authenticated identity and corresponding access control list entries. This allows the system to enforce security policies while providing customized service levels for different users and applications.

AI summary
A communication control apparatus that controls communication via a network between a first communication apparatus for communicating via a virtual communication channel and a second communication apparatus for transmitting a communication request with the first communication apparatus including a storage unit that stores access control policy defining allowance or denial of access to the first communication apparatus, an establishment unit that establishes the virtual communication channel with the first communication apparatus, an authentication unit that authenticates the second communication apparatus based on the communication request received from the second communication apparatus, an access control unit that refers to the access control policy and evaluates whether to allow or deny access from the authenticated second communication apparatus to the first communication apparatus, and a transfer unit that transfers the received communication request to the first communication apparatus when the access control unit evaluates that the access is allowed.
