Distributed Encryption Across IoT Devices to Reduce Power Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices often lack the processing power and energy resources to perform encryption, leading to increased costs and reduced data transmission frequency, necessitating a more efficient method for securing data transmissions.
Innovation Solution
Distributed encryption across multiple devices, where data is split into portions and encrypted by different devices using a shared certificate, with one device retaining a portion and merging the encrypted results before transmission to a server, ensuring security and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single IoT device performs encryption locally, then data security is improved, but processing power requirements and power consumption increase
Solution Approach 1:
The patent divides the encryption task into multiple segments, with different portions of data being encrypted by different devices in the network. Each device performs partial encryption operations rather than one device handling the entire encryption process, thereby distributing the computational burden and reducing individual device power consumption while maintaining overall data security.
2Reliability
If a single IoT device performs encryption locally, then data security is improved, but processing power requirements increase
Solution Approach 1:
The encryption workload is segmented across multiple devices in the network. Each device contributes its processing capabilities to encrypt a portion of the data, thereby distributing the total processing power requirements across the network rather than concentrating the entire burden on a single device.
3Reliability
If encryption is performed on IoT devices, then data security is improved, but data transmission frequency decreases
Solution Approach 1:
By segmenting the encryption task across multiple devices, the patent reduces the time required for each individual device to complete encryption operations. This enables more frequent data transmissions as the distributed encryption process is faster than single-device encryption, thereby improving both security and transmission frequency.
4Reliability
If more processing power is allocated to encryption, then data security is improved, but device cost increases
Solution Approach 1:
The patent segments the encryption function across multiple devices in the network, allowing each device to have lower processing power specifications. This reduces the manufacturing cost of individual IoT devices while maintaining strong data security through the collective encryption capability of the distributed network.

AI summary
Examples described herein include systems and methods for performing distributed encryption across multiple devices. An example method can include a first device discovering a second device that shares a network. The device can identify data to be sent to a server and calculate a checksum for that data. The device can then split the data into multiple portions and send a portion to the second device, along with a certificate associated with the server for encrypting the data. The first device can encrypt the portion of data it retained. The first device can receive an encrypted version of the second portion of the data sent to the second device. The first device can merge these two portions and send the merged encrypted data to the server, along with the checksum value. The server can decrypt the data and confirm that it reflects the original set of data.
