Backscattering Rectifier for Security and Identification in the context of Simultaneous Wireless Information and Power Transfer
Résumé
This article presents a proof-of-concept of an innovative security and identification mechanism for Internet of Things applications within the context of Simultaneous Wireless Information and Power Transfer. This easily integrable solution involves modifications only at the RF rectifier level of the wireless Sensing Node, enabling backscattering of the power source wave as a function of a digital private key. The wireless Sensing Node will be able to transmit identification information for a brief period. These details allow the power source system to identify the object and confirm its operational status. This mechanism adds an additional layer of security, independent and complementary of the communication protocol of the wireless Sensing Node.
