In many industrial edge computing applications, terminal devices are often remote and widely distributed.To achieve cross-domain authentication, some researchers store authentication information on a blockchain network built by edge nodes.However, since terminal equipment may be damaged or require updates to its authentication parameters, a trusted solution for deleting and modifying blockchain-stored authentication information is needed.This paper proposes using chameleon hash trap technology to maintain blockchain integrity while enabling data correction.Experimental results show that the scheme efficiently generates and distributes sub-private keys for modifying on-chain authentication data.The modifiable blockchain is well-suited for maintaining device authentication information, ensuring system security and maintainability, and improving communication efficiency.
