The invention belongs to the technical field of identity authentication, and discloses a trusted identity authentication method and system, a storage medium and a cloud computing terminal, which establish a trust relationship among multiple CAs by using a blockchain technology to complete quick response of distributed identity authentication among cross-domain PKI users. Aiming at the problems ofcomplex construction and large query time overhead of a plurality of independent PKI cross-domain identity authentication trust chains, the multi-PKI fusion certificate service system construction method enables the plurality of independent PKI systems to complete cross-authentication through a blockchain mode, and realizes credible authentication of cross-domain user identities. Aims at the spaceoverhead pressure brought to an authentication node due to the fact that the length of a blockchain is increased due to multi-domain PKI certificate chain fusion, a digital certificate authenticationquery method based on a bl
