Decentralized trusted access method for cellular base station

A decentralized trusted access method for a cellular base station, applied to a blockchain network, the method comprising:

• receiving registration information uploaded by the cellular base station, wherein the registration information comprises a public key pair and a certificate of the cellular base station;
• in response to the public key pair and the certificate, performing registration processing for the cellular base station to add the cellular base station as a member to the blockchain network;
• receiving master information block uploaded by the cellular base station, the master information block is used to indicate the basic information required for cellular users within a coverage area of the cellular base station to access the cellular base station;
• in response to the master information block, forming a block by packaging after authenticating the master information block;
• executing a consensus algorithm on the block, after satisfying consensus algorithm conditions, storing the block on the chain and generating block identification information;
• and
• returning the block identification information to the cellular base station for the cellular base station to broadcast the master information block and the block identification information to cellular users within the coverage area, allowing the cellular users within the coverage area to determine the cellular base station to be accessed based on the master information block and the block identification information, and performing uplink synchronization with the cellular base station to be accessed based on a random access procedure.

A decentralized trusted access method for a cellular base station, applied to a cellular user, the method comprising:

• acquiring a master information block and block identification information broadcast by the cellular base station, and verifying the block identification information;
• the master information block is used to indicate the basic information required for cellular users within a coverage area of the cellular base station to access the cellular base station;
• the block identification information is generated by executing a consensus algorithm on the block, and after satisfying consensus algorithm conditions, storing the block on the chain;
• the block is a data block formed by packaging after authenticating the master information block by the blockchain network;
• if the block identification information exists, verifying the block identification information, if the verification of the block identification information is successful, continuing to verify the block corresponding to the block identification information, if the verification of the block is successful, determining the cellular base station as the base station to be accessed;
• and
• performing uplink synchronization with the cellular base station to be accessed based on a random access procedure.
