One aspect provides a system and method for provisioning an access point (AP) in a wireless mesh network. During operation, a controller can obtain a set of published global encryption parameters comprising a master public key, apply an identity-based encryption (IBE) scheme to encrypt a configuration message based at least on the master public key, and transmit the encrypted configuration message to a proxy device, which forwards the encrypted configuration message to the AP. The proxy device is coupled to the controller via a previously established secure communication channel and coupled to the AP via an open communication channel. The AP can decrypt the encrypted configuration message using an AP-specific secret key generated based on a unique identifier of the AP and a master private key corresponding to the master public key, thereby facilitating provisioning of the AP based on the configuration message.

Provided are a graphene and a preparation method therefor. The method for preparing a graphene comprises following steps: i) placing a mixture of a magnesium powder and a solid oxide powder in a carbon dioxide-containing environment; and ii) heating the mixture to enable the magnesium powder to react with carbon dioxide, thereby obtaining a graphene. The specific surface area of the grapheme is 350-750 m/g, and the pore volume is 1-2 cm/g. The method for preparing a graphene in the present invention is simple and easy to carry out, and has a low cost and a high yield; and the graphene product has few impurities, a high carbon-oxygen ratio, and excellent capacitance performance and electrochemical stability.

A method for switching an operating system (OS) and an electronic apparatus are provided. While switching to a first OS, a system firmware stored in a memory unit declares that a first segment of a system memory is in a usable state and a second segment of the system memory is in a reserved state by using a first resource description table, so that the first OS is in a working state in the first segment and a second OS is in a power-saving state in the second segment. While switching to the second OS, the system firmware declares that the second segment is in the usable state and the first segment is in the reserved state by using a second resource description table, so that the second OS is in the working state and the first OS is in the power-saving state.
