Database in;An identical Encryption Algorithm is stored in instructional terminal and pair matcher;
Step S2, when instructional terminal is close to pair matcher, instructional terminal is established the first data communication with pair matcher and is connect, pairing
Device generates a random data string, and pair matcher generates the first ciphertext using Encryption Algorithm and random data string encrypted public key, and will
First ciphertext and random data string are sent to instructional terminal;
Step S3, the first ciphertext is decrypted using Encryption Algorithm and random data string in instructional terminal, and to decrypting
Public key and the public key of itself storage compare, if unanimously, by verifying for the first time, entering step S4;If inconsistent,
Terminate process;
Step S4, instructional terminal generates the second ciphertext using Encryption Algorithm and random data string encryption key, and by the
Two ciphertexts and identity information are sent to pair matcher;
Step S5, pair matcher decrypts the second ciphertext using Encryption Algorithm and random data string, and by identity information and
It decrypts obtained private key and issues Cloud Server, whether the identity information that Cloud Server confirmation receives has record in the database,
If so, entering step S6;If it is not, then terminating process;
Step S6, Cloud Server confirms whether the private key received and the private key for being stored in Cloud Server are consistent, if one
It causes, then sends identity legitimate messages to pair matcher, and enter step S7;If inconsistent, terminate process;
Step S7, it after pair matcher receives identity legitimate messages, is verified by second, and disconnects the first data communication and connect
It connects, instructional terminal is established the second data communication with pair matcher and connect;
Step S8, the user name password generation third that pair matcher serially adds close equipment using Encryption Algorithm and random data is close
Text, and third ciphertext is sent to instructional terminal;
Step S9, third ciphertext is decrypted using Encryption Algorithm and random data string in instructional terminal, and instructional terminal utilizes and sets
Standby user name password connecting multimedia device group is imparted knowledge to students.
Further, in the step S2, when the instructional terminal is close to pair matcher, instructional terminal and pair matcher establish the
One data communication connection specifically: when instructional terminal is close to pair matcher, instructional terminal and pair matcher pass through the second near-field communication mould
Block and third near-field communication module establish the connection of the first data communication.
Further, in the step S7, the instructional terminal is established the second data communication with pair matcher and is connect specifically:
The instructional terminal is established the second data communication by the first wireless communication module and second communication module with pair matcher and is connect.
The present invention has the advantages that
