Microchip Technology has announced the introduction of BodyCom™ Technology which makes use of the human body as a secure communication channel. BodyCom™ Technology works by capacitive coupling to the human body. The human body is used as the secure communications channel between a Base Unit and a Mobile Unit without any form of antenna being required:
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.
BodyCom™ Technology is supported by the free BodyCom Development V1.0 Framework and software libraries that work with all 8, 16 and 32-bit PIC® microcontrollers. The Microchip BodyCom Development Kit is also available to aid development of BodyCom designs.
