Title: SMART MANAGEMENT DEVICE, SMART LOCK DEVICE AND SMART MANAGEMENT DEVICE IDENTIFICATION METHOD
Abstract: [0001]    A smart management device (140) identification method includes: sending, by a smart management device (140), an activation request to a smart lock device (130), wherein the activation request is used to verify validity of the smart management device (140); in response to information indicating that the smart management device (140) is valid, receiving, by the smart management device (140), an access control key from the smart lock device (130), wherein the access control key is generated according to a master key of the smart lock device (130) and an identifier of the smart management device (140); and requesting, by the smart management device (140), the smart lock device (130) to perform a state switching operation using the access control key.

Claims: number: 1
text: A smart management device identification method, comprising:
number: 2
text: The method according to claim 1, wherein prior to the sending the activation request to the smart lock device, the method further comprises:
sending, by smart management device, a public key generated in the smart management device to a server, and receiving and storing a signature certificate returned by the server, wherein the server generates the signature certificate by signing the public key of the smart management device using a private key of a certificate authority center.
number: 3
text: The method according to claim 1 or 2, wherein the access control key comprises an external authentication key and an internal authentication key, and the receiving the access control key comprises:
number: 4
text: The method according to anyone of claims 1 to 3, wherein the requesting, by the smart management device, the smart lock device to perform a state switching operation using the access control key, comprises:
number: 5
text: The method according to anyone of claims 1 to 4, wherein the smart management device is a CPU card with data calculation capability and logic encryption capability or wherein the smart management device is a device in which an application having a function of access control management is installed, wherein preferably the application is an applet installed in the smart management device.
number: 6
text: A smart management device identification method, comprising:
number: 7
text: The method according to claim 6, wherein performing, by a smart lock device, authentication on the activation request, comprises:
performing, by the smart lock device, authentication on a signature certificate carried in the activation request using a public key of a certificate authority center.
number: 8
text: The method according to claim 6 or 7, wherein sending, by the smart lock device, an access control key to the smart management device, comprises:
number: 9
text: A smart management device, comprising:
an activation module (1401) configured to send an activation request to a smart lock device, wherein the activation request is used to verify validity of the smart management device, wherein preferably the activation module (1401) is further configured to:
number: 10
text: The smart management device according to claim 9, further comprising:
a sending module configured to send a public key generated in the smart management device to a server, and receive and store a signature certificate returned by the server, wherein the server generates the signature certificate by signing the public key of the smart management device using a private key of a certificate authority center.
number: 11
text: The smart management device according to claim 9 or 10, wherein the access control key comprises an external authentication key and an internal authentication key;
wherein the key obtaining module (140) is configured to:
number: 12
text: The smart management device according to anyone of claims 9 to 11, wherein the request module is configured to:
number: 13
text: The smart management device according to anyone of claims 10 to 12, wherein the activation request is sent to the intelligent lock device via near field communication or Bluetooth, and the smart management device is a CPU card with data calculation capability and logic encryption capability.
number: 14
text: The smart management device according to anyone of claims 9 to 13, wherein the smart management device is a device in which an application having a function of access control management is installed, and
the application is an applet installed in the smart management device.
number: 15
text: A smart lock device, comprising:
an activation request authentication module (1501) configured to receive an activation request sent from a smart management device, and perform authentication on the activation request, wherein preferably the activation request authentication module (1501) is further configured to:
number: 16
text: A non-transitory computer-readable storage medium, wherein when instructions in the storage medium are executed by a processor of a smart management device, the smart management device performs the smart management device identification method according to any one of claims 1 to 5.
number: 17
text: A non-transitory computer-readable storage medium, wherein when instructions in the storage medium are executed by a processor of a smart lock device, the smart lock device performs the smart management device identification method according to any one of claims 6 to 8.
