Method for realizing safe access of terminal of internet of thing

Abstract

The invention discloses a method for realizing safe access of a terminal of internet of thing, which comprises the steps of: storing an authorization message in an electronic key, and using the authorization message as an identity identification, wherein the authorization message is used as a private key signature by an authorized management node and stored in the authorized management node; writing the authorization message into the electronic key in an electronic key authorization list of the management node; when no terminal node connected with the electronic key applies to accessing the internet, searching a terminal authorization list by the management node to judge whether the access of the terminal node is allowed; and when the terminal node connected with the electronic key applies to accessing the internet, firstly executing the operation without the electronic key by the management node, and if the terminal is failed to access, searching the electronic key authorization listto judge whether the access of the terminal node is allowed. According to the method realizing the safe access of the terminal of the internet of thing, disclosed in the invention, the problem of safe access of the terminal can be effectively solved, a great amount of terminals of the internet of thing can be effectively managed, and the rapid automatic access of the terminals of the internet of thing can be realized.
