Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring the security of data reported by zero-power terminals in communication systems is a challenge, particularly in scenarios where traditional security measures are inadequate.
Innovation Solution
A communication method involving a first device that receives a wireless signal and removes interference signals using first information associated with the interference, and a second device that reports data mixed with an interference signal during transmission, ensuring secure data exchange through interference signal removal and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is transmitted by zero-power terminals, then communication functionality is achieved, but data security is compromised due to inability to employ traditional security measures
Solution Approach 1:
The patent converts the harmful interference signal into a beneficial encryption key. The base station generates an interference signal and transmits it to the zero-power terminal, which then uses this interference signal as a key to encrypt the data before transmission. This transforms the previously harmful interference into a useful security mechanism, allowing secure communication without traditional security measures.
Solution Approach 2:
The interference signal acts as an intermediary element between the base station and zero-power terminal. Instead of directly transmitting encrypted data, the system uses the interference signal as a shared secret that both parties can utilize to achieve secure communication. The base station transmits the interference signal, and the terminal uses it to encrypt data, creating a secure communication channel without requiring traditional authentication mechanisms.
2Reliability
If interference signal is added to data during transmission, then data security is improved, but signal processing complexity increases
Solution Approach 1:
The zero-power terminal performs self-encryption using the interference signal as its own encryption key. The terminal receives the interference signal from the base station and then uses this same signal to encrypt its data for transmission back to the base station. This self-service encryption mechanism simplifies the overall system complexity compared to requiring complex key exchange protocols or multiple encryption layers.
