Embodiment Construction

[0035] For smart devices based on the CPK identification authentication mechanism, the CPK security module is added to the smart device. According to the key characteristics of the CPK, the overall security mechanism is established in the CPK security module. When the smart device is connected to the Internet, all data must be encrypted. And the source of data must be confirmed, and effective security control is carried out through data encryption and data signature. This mechanism can be used with various identification methods for users, such as fingerprint / iris and other two-factor authentication methods.

[0036]

[0037] Such as figure 1 , is a system architecture diagram of the present invention.

[0038] The invention includes a smart switchgear and at least one smart key. Wherein, at least one smart key includes a management smart key with management authority, and there may be no user smart key, or one or more user smart keys.

[0039] The invention integrates the...

Abstract

The invention discloses a security control method and system based on a CPK intelligent switch device. The method comprises the following steps: a user requests to open the CPK intelligent switch device by using a user CPK intelligent key; the CPK intelligent switch device sends a challenge value to the CPK intelligent key; the CPK intelligent key performs digital signature on the challenge valueby using an own user CPK private key and returns the challenge value to the CPK intelligent switch device; and the CPK intelligent switch device extracts the stored user CPK public key, verifies whether the received digital signature is correct, verifies whether the challenge value is sent by itself, and controls to open the intelligent switch or not according to the authorization time and the authorization counts. By adoption of the scheme, the remote control of the intelligent switch device can be achieved, and remote authorization of the intelligent switch is also achieved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a security control method and system based on CPK intelligent switch equipment. Background technique [0002] According to the characteristics of the identification key of CPK, it is more secure and convenient to manage the identity authentication, identity verification and data security of smart devices than other key systems. At present, the security issue is the most important link for smart devices to connect to the network environment. Trusted identification and security authorization are the basic functions that every smart device of the Internet of Things must have. With the ability of smart devices to authenticate identities and protect data, the range of functionality that can be added expands even further. For example: smart door locks, smart car locks, smart safes, etc., not only the function of opening, but the function of enhancing authorization and sharing. [0003] F...
