Abstract

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.
