Microchip BodyCom Uses Human Body as Secure, Low-Power Communication Channel
Microchip Technology launched their BodyCom technology. It is the first framework for using the human body as a secure communication channel. BodyCom technology provides a secure, low-cost and easy method for implementing short-range, low-data-rate wireless communication with the lowest power consumption. The BodyCom Development Framework is available via free download, and it works with any of our PIC microcontrollers.
BodyCom technology does not require RF antennas. It offers low energy consumption, and increases security via bidirectional authentication. BodyCom results in simpler circuit-level designs and a lower bill of materials (BOM). All of this is enabled by the BodyCom Development V1.0 Framework, which is supplied through free software libraries that work on all of Microchip’s more than 900 8, 16 and 32-bit PIC microcontrollers.
BodyCom technology is activated by capacitively coupling to the human body. The system then begins communicating bidirectionally between a centralized controller and one or more wireless units. There are a broad range of applications where secure wireless communication is essential, and there is no more secure channel than the human body. This is especially true when you add bidirectional authentication that supports advanced encryption, such as KeeLoq technology and AES. For example, BodyCom technology helps prevent the “Relay Attack” problem that is typical in automotive passive-keyless-entry security systems.
