DATA VERIFICATION METHOD AND TERMINAL DEVICE

摘要

The present application is applicable to the technical field of computer applications. Provided are a data verification method, a terminal device and a non-volatile computer-readable storage medium. The method comprises: acquiring a node certificate of a storage node, and verifying whether the node certificate is issued by a preset trusted root certificate; if the node certificate is issued by the trusted root certificate, acquiring a public key of the storage node, and verifying, according to a pre-stored node identifier, whether the public key of the storage node is correct; and if the public key of the storage node is correct, verifying, according to the public key of the storage node, a signature in storage data stored in the storage node, and if the signature passes verification, indicating that the storage data is correct. By means of verifying a node certificate and a signature of a storage node and verifying the correctness of storage data in the storage node, the security of storage data in a node in a peer-to-peer network is improved.
