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.

AI Technical Summary

Problems solved by technology

For a wireless sensor network, it mainly faces three aspects of security issues: one is signal interference from the wireless communication process, such as attackers can block wireless communication by interfering with the communication frequency; the other is from self-organizing wireless network The problem of link vulnerability and simple network protocol, attackers can counterfeit and tamper with the transmitted information; the third is from the sensor node itself, such as the energy of ordinary low-power sensors or nodes is limited, it is difficult to load complex security Protection measures, easy to be captured and counterfeited

[0006] At present, most of the wireless sensor network node devices used at home and abroad do not perform data encryption and decryption, or only perform data encryption and decryption with symmetric algorithms, without high-security identity authentication functions, and cannot implement high-complexity security algorithms.

From the attacker's point of view, data security in such an open environment is low, the encryption key of the data transmitted over the network is easily cracked, and sensitive information is easily obtained through statistical methods

In any case, hardware is the basic condition. If the hardware does not meet the requirements, the security function cannot be realized.
