摘要
We study the decentralized identity management mechanism based on blockchain. Finally, we propose an updatable and revocable decentralized identity management scheme DIURS. In the scheme, we construct the DID management tree, which is a dynamic chameleon authentication tree essentially by using the chameleon hash function. We design algorithms in detail from four stages: system initialization, identity creation, identity update and revocation, and identity verification. We make the DID documents on the blockchain editable successfully and realize the update and revocation of DIDs. Then, we observe that DIURS can meet the structural stability and irreversibility requirements. The time of identity search and update is milliseconds. The length of the identity authentication path is short. There is no need to save the historical version of DID documents. These results indicate that DIURS is not only safe and reliable but also performs well and achieves functional optimization.
