Multimedia Middleware Security Management via Negotiated Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multimedia middleware lacks effective security management capabilities, leading to resource waste, high complexity, and vulnerability to malicious codes and viruses due to the absence of standardized security procedures and automatic negotiation processes during communication with external entities.
Innovation Solution
A security management method and apparatus for multimedia middleware that negotiates secure session setup with external entities, verifies access rights through a metadata structure specifying security algorithms and protocols, and manages license lists to ensure secure data exchange and resource access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multimedia middleware communicates with external entities without standardized security procedures, then flexibility in communication is maintained, but security management complexity increases and vulnerability to malicious codes arises
Solution Approach 1:
The patent introduces standardized security parameters including security algorithms, protocols, and session management mechanisms that transform the security processing from ad-hoc to systematic. These parameter changes enable automated security negotiations between multimedia middleware and external entities, reducing complexity while improving reliability.
Solution Approach 2:
The patent employs security management entities that act as intermediaries between multimedia middleware and external entities. These intermediaries handle security negotiations, authentication, and session management, isolating the complexity of security processing from the core multimedia functions and providing standardized security procedures.
2Productivity
If multimedia middleware lacks automated negotiation process for security algorithms, then implementation simplicity is maintained, but time and terminal resources are wasted for setting up secure channels
Solution Approach 1:
The patent implements preliminary action by pre-defining security algorithms, protocols, and negotiation procedures in the multimedia middleware. This allows automated security negotiations to occur efficiently when communication with external entities is needed, eliminating the need for time-consuming manual security channel setup while maintaining implementation simplicity through standardized templates.
3Reliability
If multimedia middleware does not use separate security process, then system simplicity is maintained, but security management effectiveness decreases
Solution Approach 1:
The patent applies universality by designing security management entities that can handle multiple security functions including authentication, authorization, encryption, and session management within a unified framework. This multi-functional approach improves security management effectiveness without proportionally increasing system complexity, as the same security infrastructure serves multiple purposes.
Data Source
AI summary
A security management method in multimedia middleware of a terminal that can download a multimedia service provided from an external entity. The security management method includes if there is an access request for a particular multimedia service, determining whether there is a corresponding multimedia service; if the access-requested multimedia service does not exist in middleware of the terminal, performing negotiation for secure session setup with the external entity; setting up a secure session to the external entity using a security parameter selected as a result of the negotiation; and receiving information for the download from the external entity through the secure session, and determining whether to execute the download.
