Abstract: 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.

Keywords: blockchain; edge computing; authentication; key agreement.
