6LoWPAN Sensor Authentication via Commissioning Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless security systems face challenges in efficient setup due to time-consuming and costly processes involving secret coding schemes for encryption, requiring trained technicians to enter encryption data.
Innovation Solution
A method for configuring a security system using a unique commissioning key formed by encrypting the IEEE or MAC address with a secret key, allowing sensors to self-organize into a wireless network and authenticate each other, reducing the need for manual encryption data entry and enabling periodic key changes without compromising security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secret coding schemes are used for encryption in wireless security systems, then security is improved, but setup time and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-provisioning each sensor with a unique commissioning key during manufacturing. This key is generated in advance and stored securely in the sensor's memory, eliminating the need for manual encryption data entry during setup. The commissioning key is used to authenticate sensors to the alarm panel automatically, resolving the contradiction between maintaining security and reducing setup time.
2Reliability
If secret coding schemes are used for encryption in wireless security systems, then security is improved, but setup complexity and cost increase
Solution Approach 1:
The patent implements self-service by enabling sensors to automatically authenticate themselves to the alarm panel using their pre-provisioned commissioning keys. The alarm panel verifies each sensor's commissioning key automatically without requiring technician intervention for encryption data entry. This self-authentication process maintains security while dramatically simplifying setup procedures and reducing dependency on trained technicians.
3Reliability
If manual encryption data entry is required, then security can be established, but the need for trained technicians increases cost and time
Solution Approach 1:
The system enables self-service authentication where sensors automatically present their commissioning keys to the alarm panel for verification. This eliminates the manual data entry process that requires trained technicians, allowing any installer to quickly configure the system by simply adding sensors to the network. Security is maintained through automatic cryptographic verification while productivity increases due to the simplified setup process.

AI summary
A method and apparatus of providing a security system. The method includes the steps of a registering sensor having a secret key and an IEEE or MAC address automatically forming a commissioning key, the registering sensor forming a registration request including the IEEE or MAC address and the commissioning key, a co-ordinator sensor receiving the wireless request for registration from the registering sensor, the co-ordinator sensor having a separate copy of the secret key, the co-ordinator sensor automatically authenticating the registering sensor via the received request for registration and the separate copy of the secret key and the registering sensor joining the co-ordinator sensor of the wireless network under the 6LoWPAN operating protocol.
