METHOD, APPARATUS, AND DEVICE FOR KEY GENERATION AND TERMINAL PROVISIONING

Provided in embodiments of the present application are a a key generation and terminal provisioning method, an apparatus, and a device thereof. The method for generating a key includes: sending, by an enrollee, a first request message to a configurator, the first request message comprising a first identifier, and the first identifier used to instruct the configurator to perform a network reconfiguration operation; receiving, by the enrollee, a first message sent by the configurator and including first key information; generating, by the enrollee, a session key according to the first key information; sending, by the enrollee, a second message to the configurator, the second message comprising second key information, thus allowing the configurator to generate the session key according to the second key information. In a process of an enrollee and a configurator performing provisioning for the first time, key information of each other is exchanged to generate a session key required for subsequent network reconfiguration performed on the enrollee, so that when the network reconfiguration is performed on the enrollee, it is unnecessary to perform an authentication process again, thereby improving the network configuration efficiency.
