Gateway Credential Segmentation for IoT Device Cloud
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current social networking systems face challenges in securely and efficiently managing access to a network of connected devices, particularly in transmitting valid credentials over restricted-size packets and ensuring real-time authorization.
Innovation Solution
A device cloud communicates with a local gateway using multiple network protocols like BTLE, WIFI, and ZIGBEE, where restricted-size packets are used to transmit credentials, and the gateway assesses authorization in real-time by reassembling the data using sequencing information from packet headers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If credentials are transmitted using restricted-size packets, then security is improved, but transmission complexity increases
Solution Approach 1:
The patent segments credentials into multiple restricted-size packets for transmission. Each packet contains a portion of the credential data along with sequencing information, allowing the gateway to reassemble the complete credentials securely while maintaining packet size restrictions that enhance security.
Solution Approach 2:
The gateway acts as an intermediary that receives restricted-size packets containing credential segments, reassembles them using sequencing information from packet headers, and then processes the complete credentials for device authorization. This intermediary role manages the complexity of segmented transmission.
2Reliability
If authorization is assessed in real-time, then security is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-segmenting credentials into restricted-size packets with embedded sequencing information before transmission. This preparation allows the gateway to quickly reassemble and process credentials in real-time without extensive processing delays, as the segmentation and sequencing framework is already in place.
3Reliability
If packets are restricted in size, then security is improved, but data transmission efficiency decreases
Solution Approach 1:
Credentials are segmented into multiple restricted-size packets that can be transmitted through security-restricted channels. Each packet includes sequencing information in its header, enabling efficient reassembly at the gateway without requiring additional overhead for error correction or retransmission protocols.

AI summary
Particular embodiments of a gateway computing device may provide a provisioning service for access credentials for a restricted network. The gateway computing device may receive, from a client device, a request for the access credentials, wherein the request was sent over an open network using a restricted-packet-size protocol designed to limit power usage by devices sending messages using the protocol. The gateway computing device may segment data comprising the access credentials into a plurality of packets, wherein the plurality of packets conform to the restricted-packet-size protocol. Finally, the gateway computing device may send, over the open network to the client device, the segmented data using the restricted-packet-size protocol.
