Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IP multimedia gateways face challenges in enabling secure communication between client devices and service managers when there are compatibility issues in security capabilities, authentication methods, cryptography methods, and access authorizations, particularly when client devices lack initial authorization to access certain content.
Innovation Solution
The method and system for an IP multimedia gateway identify client devices with incompatible security capabilities and perform authentication and cryptography translations, as well as access control conversions, to enable secure communication and content access, while maintaining accessibility for authorized devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If authentication translation is performed between different authentication methods, then compatibility between client devices and service managers is improved, but system complexity increases
Solution Approach 1:
The patent introduces an authentication translation mechanism that acts as an intermediary between client devices using different authentication methods and the service manager. This translation layer converts authentication requests from various methods into a unified format that the service manager can process, enabling compatibility without requiring the service manager to support multiple authentication methods directly, thus managing complexity through abstraction.
2Adaptability or versatility
If cryptography translation is performed between different cryptography methods, then secure communication compatibility is improved, but processing overhead increases
Solution Approach 1:
The patent implements cryptography translation that performs cryptographic conversions in advance before data transmission. By pre-processing the cryptographic translation of authentication credentials and data formats, the system avoids real-time conversion delays during actual communication sessions, reducing processing overhead during critical operations while maintaining compatibility across different cryptography methods.
3Adaptability or versatility
If access control conversion is performed for content authorization, then access flexibility is improved, but security risk increases
Solution Approach 1:
The patent implements access control conversion with feedback mechanisms that continuously monitor and verify authorization decisions. The system converts access control policies into formats compatible with different client devices while maintaining centralized policy enforcement. The feedback loop validates that converted access controls correctly reflect the intended security policies, detecting and preventing unauthorized access attempts, thus managing security risks while providing access flexibility.

AI summary
An IP multimedia gateway (IMG) may be operable to identify a client device which may not currently possess a security capability that is compatible with a security capability of a service manager for receiving a service from the service manager. A security process between the client device and the service manager may be enabled by the IMG to enable the client device to receive the service from the service manager. The client device may be local to the IMG or remote with respect to the IMG. The IMG may enable an authentication process between the client device and the service manager by performing authentication translation. The IMG may enable a cryptography process between the client device and the service manager by performing cryptography translation. The IMG may enable an authorization process for authorizing the client device to access a particular content by performing access control conversion.
