The invention discloses a verification method, device and storage medium suitable for blockchain, wherein the method is as follows: the first decryption node obtains encrypted ciphertext from the blockchain; private key and the sub-ciphertext in the N+1 sub-ciphertexts, determine the decryption intermediate result of the encrypted ciphertext on the first decryption node; the first decryption node according to the decryption of each decryption node As an intermediate result, the plaintext of the encrypted ciphertext is obtained; the first decryption node uploads the plaintext and the decryption key certificate to the block chain, and the decryption key certificate is used to verify that the plaintext is based on the obtained by decrypting the private key of the first decryption node. When the above method is applied to financial technology (Fintech), the private key of the first decryption node will not be exposed, and it can be verified that the plaintext is obtained by decrypting according to the private key of the first decryption node.
Description
technical field [0001] The present invention relates to the field of financial technology (Fintech) and the field of computer software, in particular to a verification method, device and storage medium suitable for blockchain. Background technique [0002] With the development of computer technology, more and more technologies (big data, distributed, blockchain (Blockchain), artificial intelligence, etc.) are applied in the financial field, and the traditional financial industry is gradually transforming into financial technology (Fintech). At present, in the field of financial technology, the security of financial data is very important, so financial data needs to be encrypted and decrypted during transmission. [0003] In the prior art, each decryptor has a shared private key. After decrypting the ciphertext through the shared private key, the final result is only a decrypted plaintext. To verify the correctness of decrypting the ciphertext, you need Obtain the private ke...
