The invention relates to a gateway offline authentication method, a device, a system and a computer readable storage medium, and belongs to the field of communication. A client firstly initiates verification information to a data platform to verify whether a binding relationship with a target gateway is established or not. After a data platform determines that a binding relationship is establishedbetween a client and a target gateway, a secret key is generated according to a target gateway. The multiple encryption is performed on the secret key through a pre-acquired public key correspondingto the target gateway and a private key corresponding to a client to obtain a multiple encryption secret key. The secret key and the multiple encryption secret key are sent to the client, so that theclient sends the multiple encryption secret key to the target gateway. The target gateway decrypts the multiple encryption key according to a pre-stored private key corresponding to the target gatewayand a public key corresponding to the client to obtain a key. In the process of transmitting the secret key, the secret key is also encrypted and decrypted, so that the safety of the gateway offlineauthentication process can be ensured.

Gateway offline authentication method, device, system and computer readable storage medium

The invention discloses a secure networking transmission method based on a dual encryption mechanism for an intelligent lock system. The secure networking transmission system comprises a wireless communication module, a 433 MHz-to-WIFI module and an intelligent lock body control module, wherein the wireless communication module is electrically connected with the intelligent lock body control module; the 433 MHz-to-WIFI module is used for establishing a local area network; the wireless communication module obtains a trust joining local area network of the 433 MHz-to-WIFI module according a D-Hsecret key exchange algorithm and an XXTEA encryption algorithm; the 433 MHz-to-WIFI module is used for distributing an ID number to the wireless communication module; then, the wireless communicationmodule is combined into a value according to the obtained ID number and a password sequence stored by the wireless communication module; a new communication secret key is generated through a hash operation to encrypt data and further to realize the dual encryption mechanism to guarantee wireless transmission safety, and the purposes of low power consumption and remote monitoring are achieved.
