Abstract
The invention discloses an encryption communication method of an Internet of things padlock, which is characterized in that an APP is installed in intelligent terminal equipment, after system authorization, the APP enters the intelligent terminal equipment, and is connected with the Internet of things padlock in a USB (universal serial bus) data line, nfc or Bluetooth mode and the like to control a switch, and meanwhile, data communication between the equipment and a terminal is encrypted to prevent the equipment from being cracked and stolen by people. The system is composed of an intelligent lock, an encryption part, a server and an intelligent terminal APP, wherein the intelligent lock and the intelligent terminal APP are cores of products, and an encryption algorithm and the server are mainly responsible for encryption and decryption and identity authentication of the intelligent lock. The method can open and close the padlock without an entity key through an intelligent terminal, enterprises do not need to manage the entity key, authorized operation can be performed on an unlocking person in real time, and real-time locking and unlocking information can be obtained. Meanwhile, in order to solve the problem that the lock is stolen by others, unlocking communication needs to be carried out in an encryption mode.
Description
Technical Field
The invention relates to an encryption communication method, in particular to an encryption communication method of an Internet of things padlock.
Background
The traditional padlock adopts an entity key to carry out locking and unlocking operation, the management of the entity key becomes a difficult point of enterprises, and the massive traditional mechanical locks have the defects of high key management difficulty, poor safety, high personnel maintenance cost and many management loopholes. The maintenance personnel work load is big, need carry many keys.
The control means is deficient: the locks are distributed in a city in a remarkable fragmentation mode, the box body or the lock body is damaged and moved, and the like, so that the management center cannot update the information of the locks in time. Management is in the form of a tangle that is difficult to manage and maintain, despite insecurity.
The monitoring method is lack: because of constructor, the change of patrolling and examining personnel, the key appears duplicating easily, loses reason leak very big, can't carry out effectual supervision to the personnel of unblanking, time, authority.
The maintenance efficiency is very low: relying on manual maintenance and management, there is a lack of normative support systems.
Therefore, developing an encryption communication method for the padlock of the internet of things becomes a problem to be solved urgently by those skilled in the art.
Disclosure of Invention
In order to solve the defects, the invention provides an encryption communication method of an internet of things padlock.
The above object of the present invention is achieved by the following technical means: an encryption communication method of an Internet of things padlock is characterized in that: the method comprises the following steps:
s1: after the intelligent terminal and the intelligent lock are successfully connected, reading specific data played (plaintext) in the intelligent lock, and encrypting by adopting a CA (conditional access) algorithm to form a ciphertext;
s2: the method comprises the steps that an intelligent terminal APP pushes acquired plain text data to a server, the server encrypts the data to form a ciphertext, and the ciphertext is stored in a database to be used as an encryption and decryption private key;
s3: the method comprises the steps that an intelligent terminal APP sends a command to an intelligent lock, the command data are encrypted according to a ciphertext data private key acquired from a server, an encrypted command string is generated and sent to the intelligent lock;
s4: after receiving the confidential command string, the intelligent lock reads a specific play (plaintext) of the intelligent lock, then performs encryption operation by adopting an encryption algorithm the same as that of the intelligent terminal APP to form a ciphertext (ciphertext), and decrypts the received encrypted string as a private key to obtain a command to be operated and execute the command;
s5: after the command is executed, the intelligent lock encrypts data needing to be transmitted back to the intelligent terminal APP by using a ciphertext (ciphertext) to form a returned encrypted string, and transmits the returned data to the server for encryption operation to obtain actual returned data;
s6: and the intelligent terminal APP displays the execution result of the command according to the returned data.
Further, in step S1, the intelligent terminal and the intelligent lock are linked by installing an APP in the intelligent terminal device, and after the system is authorized, the intelligent terminal and the intelligent lock enter the APP and are connected with the padlock of the internet of things by means of a USB data line, nfc, bluetooth or the like.
Further, the system is composed of an intelligent lock (device), an encryption (encrypt), a server (server) and an intelligent terminal APP (client).
The invention can prevent the data from stealing or leaking. The integrity of the data is guaranteed, and the data transmitted by communication is prevented from being tampered. And the identity of the two communication parties is confirmed to ensure the data source and the legal user.
Compared with the prior art, the invention has the advantages that: the method can open and close the padlock without an entity key through an intelligent terminal, enterprises do not need to manage the entity key, authorized operation can be performed on an unlocking person in real time, and real-time locking and unlocking information can be obtained. Meanwhile, in order to solve the problem that the lock is stolen by others, unlocking communication needs to be carried out in an encryption mode.
