A portable multi-scenario teaching identity authentication method

Abstract

The present invention provides a portable multi-scenario teaching system, comprising the following steps: step S1, writing identity information, public key and private key into the teaching terminal and cloud server; step S2, establishing the first data when the teaching terminal is close to the pairing device Communication connection, the pairer encrypts the public key to generate the first ciphertext and sends it to the teaching terminal; step S3, the teaching terminal decrypts the first ciphertext and compares whether it is consistent with the public key stored by itself; step S4, the teaching terminal encrypts the private key to generate The second ciphertext and its identity information are sent to the pairing device; Step S5, the pairing device decrypts the second ciphertext and sends it to the cloud server, and the cloud server notifies the pairing device after confirming that the identity is legal; Step S6, the pairing device establishes the second data communication Connection; step S7, the pairing device encrypts the username and password to generate a third ciphertext and sends it to the teaching terminal; step S8, the teaching terminal decrypts the third ciphertext to obtain the username and password. The invention has the advantages of improving the security of the identity authentication process of the teaching terminal.

Description

technical field [0001] The invention relates to an identity authentication method, in particular to a portable multi-scene teaching identity authentication method. Background technique [0002] With the advancement of technology, classroom equipment is also advancing with the times, and various teaching equipment have also been updated. Multimedia teaching has become an indispensable teaching form in every classroom. In current classrooms, a set of multimedia equipment and corresponding teaching terminals will be installed, and each teaching terminal corresponds to controlling various sub-equipments under a set of multimedia equipment in a classroom. [0003] In order to facilitate the management of teaching terminals and multimedia equipment, and to check the teacher's class time and get out of class time, it is necessary to perform identity recognition and account password pairing operations on the teaching terminal. However, if an unauthorized person knows the pairing co...
