IP Camera Security System Key Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IP camera security systems face performance degradation due to the need for multiple encryption and decryption processes in image storage devices, and security vulnerabilities arise from managing encryption keys in IP cameras and client terminals.
Innovation Solution
Implementing an IP camera security system where the image storage device manages the encryption key and method, transmitting them through a separate security session from the data transport session, and avoiding decryption and re-encryption processes in the image storage device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image storage device performs multiple encryption and decryption processes for IP camera image transmission and storage, then network security is improved, but the performance of the image storage device is significantly lowered
Solution Approach 1:
The patent extracts the encryption and decryption operations from the image storage device and relocates them to the IP camera and client terminal respectively. The image storage device only performs secure transmission of encryption keys and methods, while the actual encryption/decryption is handled by endpoints with sufficient processing power, thus relieving the performance burden from the storage device.
Solution Approach 2:
The patent introduces encryption keys and encryption methods as intermediaries that enable secure communication without requiring the image storage device to perform multiple encryption/decryption operations. The key management system acts as a mediator that distributes cryptographic materials to appropriate parties, allowing secure data flow while maintaining storage device performance.
2Adaptability or versatility
If IP cameras and client terminals manage their own encryption keys, then encryption flexibility is improved, but security vulnerabilities increase
Solution Approach 1:
The patent adds a new dimension to key management by introducing a hierarchical structure where encryption keys are distributed through a controlled key management system rather than being independently generated. This creates a multi-layered security architecture that maintains flexibility while adding centralized control to mitigate vulnerabilities.
Solution Approach 2:
The patent implements a feedback mechanism where the image storage device receives confirmation from IP cameras and client terminals about successful key reception and usage. This allows the system to monitor and control the distribution and usage of encryption keys, ensuring security policies are enforced while maintaining operational flexibility.

AI summary
An IP camera security system allowing secure encryption information to be transmitted is provided that is implemented such that an encryption key and an encryption method are managed not by an IP camera and a client terminal vulnerable to security but by an image storage device having robust security so as to further secure the network segment security.
