Abstract

This application relates to the field of terminals, and discloses a method and device for obtaining credentials, which are used to solve the problem that the current method of obtaining credentials has a small application range. The method includes: the terminal sends a first request message to the block chain, the first request message is used to obtain the first identification of the first access target of the terminal, and the first request message includes the identification of the terminal; the terminal receives the target address sent by the block chain The first response message of the first request message, the first response message includes the first token, the first token includes the first identification; the terminal sends the second request message to the first access target according to the first identification, the second request message Used to obtain credentials for accessing the first access target, the second request message includes the identification of the terminal and the first token; the terminal receives the second response message sent by the first access target, and the second response message includes information for accessing the first access target credentials. It is suitable for IoT scenarios and other scenarios, and has a wide range of applications.

Description

technical field [0001] The embodiment of the present application relates to the field of terminals, and in particular to a method and device for obtaining credentials. Background technique [0002] Access control plays a very important role in the cellular network, protecting spectrum resources and communication resources, and is the prerequisite for the cellular network to provide mobile communication services for terminals. If a terminal wants to access a cellular network of a mobile network operator (mobile network operator, MNO) (hereinafter referred to as the operator), it needs to obtain a credential for accessing the operator. In the prior art, the operator's network is accessed by embedding a credential for accessing the operator in a subscriber identity module (subscriber identity model, SIM) card of the entity. [0003] If the user wants to change the operator, the SIM card needs to be replaced. In the IoT scenario, the number of IoT terminals is huge. If the SIM...
