Embodiments of the disclosure provide a Bluetooth network, a communication method, an apparatus, and a storage medium thereof. In the embodiments of the disclosure, a Bluetooth network comprises a Bluetooth node configured with a forwarding capability and serving as a non-leaf node, and a Bluetooth node functioning in a Bluetooth advertising mode to serve as a leaf node. Each leaf node is connected to at least one of one or more non-leaf nodes. Via the forwarding capability of the non-leaf node, the leaf node communicates with other leaf nodes or non-leaf nodes not within its signal coverage, thereby extending a communication range of a Bluetooth node.

Bluetooth network, communication method, apparatus, and storage medium thereof

The disclosure provides a key generation method and apparatus. The key generation method comprises: encrypting a first key factor generated by a first device with an initial key, and sending the encrypted first key factor to a second device through a first secure channel, wherein the initial key is a key preset for the first device and the second device; receiving, through the first secure channel, a second key factor encrypted with the initial key, wherein the second key factor is generated by the second device; decrypting the second key factor encrypted with the initial key and received through the first secure channel, so as to obtain the second key factor; and generating a shared key between the first device and the second device according to the first key factor and the second key factor. According to the disclosed embodiments, a gateway device is unable to acquire a shared key negotiated between a first device and a second device, ensuring the security of data transmitted there between, and further reducing the risk of data being illegally captured during transmission.

Key generation method and apparatus using double encryption

A verification information update method includes: receiving a first request message for binding to a smart device from a terminal device, the first request message carrying a universally unique identifier (UUID) of the smart device; determining a binding relationship between the UUID and a user identifier of the terminal device, and generating a session random number corresponding to the binding relationship; and generating a new verification number and a new verification password of the smart device based on the session random number. The technical solution of the present disclosure implement dynamic update of verification information during a session, thus increasing the difficulty in monitoring the verification information during update.

Verification information update

Disclosed herein are methods, apparatuses, and systems for remotely accessing cloud applications. In one embodiment, the method comprises receiving an access request of a requester, sent by a cloud server, requesting being accessed by a controlling party; establishing a secure channel with the cloud server based on the access request of the requester, sent by the cloud server, requesting being accessed by the controlling party; receiving, via the safety channel, a login key generated based on the access request of the requester sent by the cloud server; generating, based on the login key, a login request for logging into the requester and sending the login request to the cloud server; receiving mode information of a login success returned by the cloud server after the cloud server verifies the login request; and receiving current mode information of the requester pushed by the cloud server, and entering a remote access mode for the requester. The disclosed embodiments can solve the following problems: remote access is not possible between different operating systems; a request for remote access cannot be made between terminals; and wasting unnecessary resources on site traffic. In addition, the method also prevents the risk of password leakage during remote access.
