| 英文摘要 | Verification of transaction amount for ciphertext status, this paper used the principle of safe multi-party computing and proposed a new random two-state encoding method. Using this encoding method and randomly generated full-order set encoded transaction, this paper constructed a code vector that made the transaction completely match one by one. Therefore, it transformed the transaction confidentiality verification problem into the partial element confidentiality accumulation in coding vector. By accumulating the results to distinguish the transaction relationship, it combined with ECC and homomorphic characteristics to solve the problem of the transaction confidentiality verification. Finally it used the simulation example under the semi-honest model to prove the correctness and safety of the method. Theory analysis shows that compared with the existing methods, the proposed method has the advantages of short key and strong practicability. |
