Online Generation Method of Cryptocurrency Address Based on Combined Public Key

Abstract

The invention discloses an online generation method for a cryptographic currency address based on a combined public key. The method comprises a system initialization process, an address generation process and a payment signing process. In the system initialization process, a private key and a public key matrix with a fixed size are generated by a wallet; the private key is stored in a private key storage area; and the public key matrix is stored in an online storage area of the wallet. In the address generation process, each time when the wallet receives payment, the wallet exports a corresponding unique address from the public key matrix through a unique transaction serial number, and in this process, the private key storage does not need to be accessed. In the payment signing process, the wallet generates a corresponding private key through the unique transaction serial number, and a signature is generated through the private key, thereby finishing payment. The cryptographic currency is Bitcoin, Litecoin or Ethereum. Through utilization of the method, a transaction address can be generated rapidly, the private key does not need to be accessed directly, and the private key and address management cost of the wallet is greatly reduced.

Description

technical field [0001] The invention relates to the field of cryptographic currency, in particular to an online generation method of cryptographic currency addresses based on combined public keys. Background technique [0002] The user client of cryptographic currencies based on blockchain technology such as Bitcoin is called a wallet (Wallet). As a client, a wallet can be either an application or a hardware. Users establish and manage their own accounts through the wallet, and conduct transactions in the cryptocurrency network through the wallet. Transactions mainly include transferring the balance of one's own account to other users, or receiving payments from other users. [0003] Before trading, users need to first generate a personal account based on public key cryptography through the wallet. Bitcoin and its derivative cryptographic currencies generally use elliptic curve cryptography as the public key cryptographic algorithm for constructing accounts. The user gene...

Although this strategy reduces the access frequency of the private key storage area to a certain extent, it still needs to visit the private key storage area regularly. The number of accesses and storage overhead of the private key storage area is still linearly related to the transaction volume, and does not reduce the address and private key storage overhead and management overhead
