Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in effectively managing and installing valid certificates and certificate issuer information in 5G communication systems, particularly for IoT networks, which are crucial for secure data transmission and device authentication.
Innovation Solution
A method and apparatus that enable a local bundle assistant (LBA) to negotiate certificates with a secondary platform bundle manager (SPBM) in a wireless communication system, involving the transmission and reception of certificate information and public key identifiers to establish secure key agreements and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If certificates and certificate issuer information are managed and installed in 5G communication systems for IoT networks, then security and authentication reliability is improved, but device complexity and management overhead increases
Solution Approach 1:
The patent introduces a bundle manager as an intermediary component that centralizes the management of certificates and certificate issuer information. This mediator handles the complex tasks of certificate installation, validation, and updates, thereby improving security reliability while shielding individual devices from the complexity of cryptographic management. The bundle manager coordinates between certificate authorities, devices, and security modules, resolving the contradiction by centralizing control.
Solution Approach 2:
The patent segments the certificate management system into distinct functional components: certificate issuance by authorities, bundle creation by the bundle manager, certificate installation by devices, and validation by security modules. This segmentation allows each component to specialize in specific tasks, improving overall system reliability while reducing the complexity burden on individual devices by distributing management responsibilities across the architecture.
2Adaptability or versatility
If multiple certificates and certificate issuers are negotiated and managed between LBA and SPBM, then authentication capability and security service versatility is improved, but information management complexity increases
Solution Approach 1:
The bundle manager is designed as a universal component that can negotiate and manage multiple types of certificates from different certificate issuers. It provides multi-functional capabilities including certificate selection, validation, installation, and updates across various 5G IoT scenarios. This universality enables the system to support diverse authentication requirements and security services while the bundle manager handles the underlying information management complexity centrally, reducing the burden on individual devices.
3Reliability
If secure key agreement and authentication are established through certificate negotiation, then data transmission security is improved, but communication overhead and time consumption increases
Solution Approach 1:
The patent implements preliminary action by having the bundle manager negotiate and install certificates and certificate issuer information before actual data transmission occurs. This advance preparation ensures that security credentials are already in place and validated, so when secure communication is needed, the key agreement and authentication processes can proceed efficiently without delays. The preliminary certificate installation resolves the contradiction by trading initial setup time for faster subsequent secure communications.

AI summary
A method of a local bundle assistant (LBA) negotiating a certificate with a secondary platform bundle manager (SPBM) in a wireless communication system including: transmitting a request message requesting information of certificates supported by a secondary secure platform (SSP) to a secondary platform bundle loader (SPBL) of the SSP; receiving the information of certificates supported by the SSP including information of certificate issuers corresponding to a family identifier from the SPBL; transmitting the information of certificates supported by the SSP to the SPBM; and receiving a certificate of the SPBM for key agreement, information of public key identifiers of certificate issuers to be used by the SSP, and information of the family identifier from the SPBM.
