WVAN Security Module Key Generation and Domain Manager
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless video area networks (WVANs) face security issues as data transmitted between devices may not be secure, allowing unauthorized devices to access private user data.
Innovation Solution
A security module generates and updates cryptographic keys to establish a secure relationship between devices in a WVAN, with a domain manager maintaining an authorized list of station devices, ensuring only verified devices can join and operate within the network, using public-key cryptography and authentication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is implemented in WVAN, then communication convenience and network accessibility are improved, but data security and privacy protection deteriorate
Solution Approach 1:
The patent implements preliminary authentication and key establishment before data transmission begins. The domain manager pre-authenticates station devices and establishes cryptographic keys in advance, ensuring that only authorized devices can join the network and transmit data, thereby preventing unauthorized access while maintaining wireless convenience
Solution Approach 2:
The patent introduces a domain manager as an intermediary entity that mediates authentication and key distribution between devices. The domain manager verifies device credentials, manages cryptographic keys, and controls network access, providing a centralized security mechanism that protects data transmission without compromising network accessibility
2Object-affected harmful factors
If cryptographic key management is implemented, then data encryption and security are improved, but system complexity and computational overhead increase
Solution Approach 1:
The patent extracts the complex cryptographic key management functions into a separate domain manager entity. This separates security-critical operations from regular data transmission processes, allowing the authentication and key establishment mechanisms to be handled by a specialized component while keeping the overall system architecture relatively simple and modular
Data Source
AI summary
A device is disclosed including a security module to generate and update cryptographic keys to establish a secure relationship between the device and one or more station devices in a wireless video area network (WVAN) and a domain manager to maintain a list of the station devices that are authorized to operate in the WVAN.
