[0057] Such as figure 1 As shown, the present invention provides a method for constructing a distributed public key infrastructure based on an editable blockchain, and its implementation method is as follows:
[0058] S1. Initialization system: Generate the public key and trapdoor key of the Chameleon hash function, and build an editable blockchain based on the Chameleon hash function, and broadcast the public key to the editable blockchain, using secret sharing The method generates the subkey of the chameleon hash trapdoor key, distributes the subkey to the CA node and keeps it secret;
[0059] S2. Deploy smart contracts: respectively deploy the main contract, signature generation contract, certificate issuance contract, certificate update contract and certificate revocation contract in the editable blockchain. The implementation methods are as follows:
[0060] S201. Deploy the main contract: deploy the main contract for receiving user requests in the editable blockchain; ...
