The invention discloses a short-distance
wireless communication node and a
wireless communication method. The short-distance
wireless communication node acquires a plurality of types of sensing information or accesses a universal
bus to form a self-organization communication network with security identification and
encryption functions. The short-distance wireless communication node is mainly characterized in that an
embedded security algorithm coprocessor is installed on hardware to allow wireless node equipment to have low-power-consumption and high-speed
encryption and decryption calculation capacities of performing a complicated
algorithm such as Rivest-Shamir-Adleman (RSA),
error checking and correcting (ECC) and
advanced encryption standard (AES), thereby improving
wireless network access identification and
data stream encryption and decryption, and improving the
information security of a network is through hardware enhancement. According to the functions of a
wireless network, the short-distance wireless communication node can serve as front-end acquisition equipment as well as routing equipment and gathering equipment; and as being externally provided with a plurality of universal
bus interfaces, the short-distance wireless communication node can be conveniently connected with the conventional security protection sensor or network, so that the security and the credibility of the conventional
system during wireless communication expansion are improved to adapt to applications with relatively
high security level demands. The short-distance wireless communication node can be applied to the security protection fields of
fire prevention, theft prevention, intelligent monitoring and the like.
