Detailed Description
Referring to fig. 1, an intelligent access control system according to an embodiment is provided, which includes an intelligent access control, an intelligent terminal, and a server, where when the intelligent access control performs data communication with the server through the intelligent terminal, data encryption is required to be performed in order to ensure communication security. On one hand, after the connection between the intelligent terminal and the intelligent access control is established, the intelligent terminal can generate a first key pair, namely a first public key and a first private key, the intelligent terminal sends the first public key to the intelligent access control, the intelligent access control can generate the first key for establishing a data security transmission channel, the first key is encrypted according to the first public key and then sent to the intelligent terminal, and the intelligent terminal decrypts the encrypted first key according to the first private key to obtain the first key. On the other hand, when the intelligent access control is activated, a second key pair, namely a second public key and a second private key, is generated, the intelligent access control sends the second public key to the intelligent terminal, the intelligent terminal forwards the second public key to the server side, the second key is generated at the server side, the server side encrypts the second key according to the received second public key and sends the second key to the intelligent terminal, the intelligent terminal receives the encrypted second key and sends the second key to the intelligent access control, and the intelligent access control decrypts the encrypted second key according to the second private key and then can obtain the second key, namely the intelligent access control obtains the second key sent by the server side. Through the process, the intelligent access control can safely obtain the first secret key and the second secret key, the intelligent terminal can safely obtain the first secret key, and the server side can obtain the second secret key.
When an intelligent system needs to transmit data or information, for example, when the intelligent access control needs to transmit information to a server, firstly, double encryption is performed on the information to be transmitted according to a first secret key and a second secret key to obtain double encryption information, the double encryption information is transmitted to an intelligent terminal, the intelligent terminal performs single-layer decryption on the double encryption information according to the first secret key to obtain single-layer encryption information, the single-layer decryption information is decrypted by the server according to the second secret key to obtain the information to be transmitted, the information to be transmitted is transmitted by the intelligent access control, and the information transmission safety between the intelligent access control and the server can be realized through double encryption corresponding to a solid line part in fig. 1. For another example, when the server needs to send data to the smart door control, the server encrypts the original data according to the second key and sends the encrypted original data to the smart terminal, the smart terminal encrypts the encrypted original data again according to the first key to obtain double-encrypted data and sends the double-encrypted data to the smart door control, and the smart door control receives the double-encrypted data and then double-decrypts the double-encrypted data according to the first key and the second key to obtain the original data sent by the server, so that communication between the server and the smart door control is realized, corresponding to a dotted line part in fig. 1, because the server and the smart terminal are both encrypted, that is, double-encrypted, data transmission safety can be ensured. The process of sending the information to the server by the intelligent door sensor is not sequential to the process of sending the data to the intelligent door sensor by the server, and the processes can be performed simultaneously, that is, the sequence of the solid line part and the dotted line part in fig. 1 can be changed, and the processes can also be performed simultaneously. Specifically, when the intelligent access control communicates data or information with the server, the symmetric key is used for encryption and decryption, that is, the same key is used for encryption and decryption. When public key transmission is carried out between the intelligent access control and the server side and between the intelligent access control and the intelligent terminal, asymmetric encryption is adopted, namely, a public key is adopted during encryption, and a private key is adopted during decryption, namely, different keys are adopted for encryption and decryption respectively.
Referring to fig. 2, an embodiment of a data processing method for an intelligent access control system is provided, which is applied to an intelligent terminal and includes the following steps:
s210: and receiving the encrypted original data obtained by encrypting the original data by the server according to the first key.
When the server needs to send data to the intelligent access control, the server first needs to obtain original data, namely the data to be sent which needs to be sent to the intelligent access control, a first secret key for encryption is generated at the server, the original data to be sent is encrypted according to the first secret key to obtain the encrypted original data, the original data in an encryption area is sent to the intelligent terminal, and the intelligent terminal receives the encrypted original data. Specifically, the first key generated by the server may be decrypted successfully after a certain time, that is, when data is encrypted and transmitted through the first key, there is a risk that the same first key is used for encrypting for a certain time.
S220: the second key is read.
At the intelligent access control, a second key used for establishing a data security transmission channel can be generated, namely the second key can be randomly generated at the intelligent access control and used for encrypting data, in order to ensure that the data can be safely transmitted before the intelligent access control and the intelligent terminal, the intelligent terminal can decrypt the data transmitted by the intelligent access control and the intelligent terminal can encrypt the data sent by the server side, the intelligent access control needs to transmit the generated second key to the intelligent terminal, namely the intelligent terminal needs to acquire and store the second key of the intelligent access control in advance, and when the intelligent terminal needs to encrypt the data sent by the server side or decrypt the information sent by the intelligent access control according to the second key, the second key stored in the intelligent terminal needs to be read for encryption or decryption. That is, when the encrypted original data sent by the server needs to be encrypted again after being received, the stored second key is read, and then the encrypted original data is encrypted again according to the second key.
S230: and encrypting the encrypted original data according to the second key to obtain double encrypted data.
S240: and transmitting the double-encrypted data to the intelligent access control.
Because the intelligent terminal is used as an intermediary for communication between the server and the intelligent access control, whether data transmission is safe or not is related to whether the whole transmission process is safe or not, in order to ensure the safety of data transmission, after the intelligent terminal receives encrypted original data obtained by encrypting the original data by the server according to the second secret key, the encrypted original data needs to be encrypted again according to the read second secret key, namely, the original data is encrypted twice to obtain double-encrypted data. And encrypting the encrypted original data again through the intelligent terminal so as to further ensure the safety of the data transmitted to the intelligent entrance guard by the intelligent terminal. The intelligent access control can decrypt the double-encrypted data after receiving the double-encrypted data to obtain the original data sent by the server, so that safe passing between the server and the intelligent access control is realized.
According to the data processing method of the intelligent access control system, when the server side sends original data to the intelligent access control through the intelligent terminal as an intermediary, the intelligent terminal encrypts the original data sent by the server side according to the second secret key to obtain double-encrypted data and sends the double-encrypted data to the intelligent access control, namely, the original data needing to be sent to the intelligent access control by the server side is firstly encrypted by the server side and sent to the intelligent terminal to ensure the communication safety between the server side and the intelligent terminal, then the double-encrypted data is encrypted by the intelligent terminal and sent to the intelligent access control, so that the communication safety between the intelligent terminal and the intelligent access control is further ensured, and the communication safety is ensured through double-encryption.
Referring to fig. 3, in one embodiment, the data processing method of the intelligent access control system further includes the steps of:
s250: and receiving double encryption information sent by the intelligent entrance guard.
S260: and decrypting the double encrypted information according to the second key to obtain single-layer encrypted information.
S270: and sending the single-layer encryption information to the server.
Specifically, in the intelligent terminal, the step of receiving the double encryption information sent by the intelligent access control and the step of receiving the encrypted original data are not in sequence, that is, the two steps can be performed simultaneously, the double encryption information can be received first and then the encrypted original data can be received, the encrypted original data can be received first and then the double encryption information can be received, that is, the intelligent terminal can process the data received from the service end at any time and can process the information received from the intelligent access control at any time.
When the intelligent entrance guard needs to send information to the server, the intelligent entrance guard firstly double encrypts the information to be sent and sends the information to the intelligent terminal, the intelligent terminal receives the double encrypted information sent by the intelligent entrance guard and then decrypts the information once according to a second secret key, the double encrypted information is information encrypted twice through a first secret key and a second secret key, the second secret key is stored in the intelligent terminal, so that single-layer encrypted information can be obtained by decrypting the double encrypted information once according to the second secret key, the single-layer encrypted information, namely the information to be sent is encrypted according to the first secret key and then is sent to the server, and the first secret key is stored in the server, so that the information to be sent by the intelligent entrance guard can be obtained by decrypting the single-layer encrypted information according to the first secret key after the server receives the single-layer encrypted information, because the information to be sent is doubly encrypted in the intelligent access control, the intelligent access control can safely transmit the information to the server.
Referring to fig. 4, in one embodiment, before the step of reading the second key, the method further includes the steps of:
s401: and acquiring a first public key and a first private key corresponding to the first public key.

S403: and receiving an encrypted second key obtained by encrypting the second key by the intelligent access control according to the first public key.
S404: and decrypting the encrypted second key according to the first private key to obtain the second key and storing the second key.
At intelligent entrance guard, can generate a second key that is used for establishing data security transmission channel, in order to ensure that intelligent entrance guard and intelligent terminal can safe transmission data before and intelligent terminal can decipher the data that intelligent entrance guard transmitted, intelligent entrance guard need give intelligent terminal with the second key transmission who produces. In order to ensure the transmission security of the second key of the intelligent access control and the intelligent terminal, a first key pair, namely a first public key and a first private key corresponding to the first public key are generated in the intelligent terminal, thereby obtaining a first public key and a first private key corresponding to the first public key, the information encrypted by the second public key can be unlocked only by the second private key corresponding to the second public key, and sends the first public key to the intelligent entrance guard, the intelligent entrance guard encrypts the second key according to the first public key after receiving the first public key sent by the intelligent terminal to obtain an encrypted second key, and the intelligent terminal decrypts the encrypted second key according to the first private key corresponding to the first public key to obtain and store the second key sent by the intelligent access control, and the second key can be read when the second key is subsequently required to be encrypted or decrypted.
Referring to fig. 5, the present invention further provides an embodiment of a data processing method for an intelligent access control system, which is applied to an intelligent access control system, and includes the following steps:
s510: and receiving the double encrypted data sent by the intelligent terminal.
When the server sends original data to the intelligent access control, the original data are encrypted according to the first secret key and then sent to the intelligent terminal, the intelligent terminal encrypts the encrypted original data again to obtain double-encrypted data and then sends the double-encrypted data to the intelligent access control, and the intelligent access control receives the double-encrypted data.
S520: the first key and the second key are read.
S530: and decrypting the double encrypted data according to the first key and the second key to obtain the original data.
If the intelligent access control wants to obtain the original data sent by the server, the intelligent access control needs to perform double decryption on the received double encrypted data, so that the stored first key and the stored second key need to be read at first, and the double encrypted data is subjected to double decryption through the first key and the second key, so that the original data can be obtained.
Specifically, the step of decrypting the doubly encrypted data according to the first key and the second key to obtain the original data includes decrypting the doubly encrypted data according to the second key to obtain the encrypted original data; and decrypting the encrypted original data according to the first key to obtain the original data. That is to say, when the server sends the original data to the smart door sensor, the original data is firstly encrypted according to the first secret key and then sent to the smart terminal, and the smart terminal then re-encrypts the encrypted original data according to the second secret key to obtain the double-encrypted data, that is, the original data is firstly encrypted by the first secret key and then encrypted by the second secret key, so that when decrypting, the double-encrypted data is firstly decrypted according to the second secret key and then decrypted according to the first secret key.
According to the data processing method of the intelligent access control system, after the intelligent access control receives the double-encrypted data sent by the intelligent terminal, double decryption is carried out on the double-encrypted data to obtain the original data sent to the intelligent access control by the server, and data communication is achieved. The double-encrypted data is the data obtained by encrypting the original data by the server side and then encrypting the original data by the intelligent terminal, namely the double-encrypted data is the data obtained by encrypting the original data twice, and then carrying out double decryption on the double-encrypted data to obtain the original data.

s640: and acquiring information to be sent.
S650: and carrying out double encryption on the information to be sent according to the first key and the second key to obtain double encryption information.
When the intelligent access control needs to send information to the intelligent terminal, the intelligent access control firstly needs to acquire information to be sent, and in order to ensure the information communication safety, the information to be sent needs to be doubly encrypted according to the first secret key and the second secret key to acquire double information. That is, the double encryption information is obtained, and if the double decryption page is not performed on the double encryption information by the first key and the second key, the information sent to the intelligent terminal by the intelligent access control cannot be obtained, that is, the communication security is ensured by the double encryption mode. The step of receiving the double-encrypted data sent by the intelligent terminal and the step of acquiring the information to be sent can be switched in sequence and can also be carried out simultaneously, that is, the intelligent access control can firstly receive the double-encrypted data sent by the intelligent terminal and then acquire the information to be sent, and can also firstly acquire the information to be sent and then receive the double-encrypted data sent by the intelligent terminal and also can see to be carried out simultaneously.
Specifically, the information to be sent is doubly encrypted according to a first key and a second key, and the step of obtaining doubly encrypted information comprises the steps of encrypting the information to be sent according to the first key to obtain the encrypted information to be sent; and encrypting the encrypted information to be sent according to the second key to obtain double encrypted information. That is to say, because the intelligent terminal only comprises the second key, the first key is stored in the server, and the intelligent terminal intelligently decrypts the double encryption information according to the second key, when the original data is encrypted in the intelligent door magnet, the encryption is performed according to the first key and then the encryption is performed according to the second key, so that the intelligent terminal can decrypt once according to the second key after obtaining the double encryption information to obtain the single-layer encryption information.
S660: and sending the double encryption information to the intelligent terminal.
After the double-encryption information is obtained, the double-encryption information is sent to the intelligent terminal, the intelligent terminal can decrypt the double-encryption information once according to the second secret key to obtain single-layer encryption information and send the single-layer encryption information to the server, and the single-layer encryption information is also a single-encryption result of the information to be sent, so that the information to be sent has a protection effect. The server side can generate and store the first secret key, and the server side can obtain the information to be sent, which is sent to the server side by the intelligent access control, by decrypting the first secret key once according to the first secret key, so that the safe communication between the intelligent access control and the server side is realized.

S702: and generating a second public key and a second private key corresponding to the second public key.
In the process of using the access control for the first time, a registered user of an APP (application) with an access control function is required to activate the used intelligent access control through strict authority control. The intelligent access control can generate and store a second key pair, namely a second public key and a second private key corresponding to the second public key in the activation process, so that the second public key and the second private key corresponding to the second public key can be obtained, and the information encrypted by the second public key can be unlocked through the second private key corresponding to the second public key.
S703: and sending the second public key to the intelligent terminal.

The server side can generate a first secret key, and in order to enable the intelligent door to decrypt data encrypted by the server side through the first secret key, the server side needs to send the first secret key to the intelligent door. In order to ensure the transmission safety of the first secret key, the intelligent terminal is used as an intermediary to send a second public key to the server, the server encrypts the first secret key according to the second public key and transmits the encrypted first secret key to the intelligent entrance guard through the intelligent terminal, namely, the intelligent entrance guard can obtain the encrypted first secret key so as to ensure the transmission safety of the first secret key.
