Abstract

The invention discloses a block chain digital asset key management method and system based on an SIM card. The method comprises the steps that an asset wallet App sends a wallet creation application to a service background; the SIM card receives the creation instruction, and the in-card key management intelligent application generates a corresponding key pair; then, the public key is returned to a service background or directly returned to the App, and SIM card chip hardware is called to store the private key; the App receives the public key and performs corresponding operation on the target block chain digital assets; the target block link receives the asset operation request and returns an account decryption or transaction signature requirement; the App receives the encryption, decryption or signature requirement and initiates a request for encrypting, decrypting or signing a ciphertext or a transaction; and the SIM intelligent application calls a private key stored in the chip hardware to encrypt, decrypt or sign the request. The SIM card of the operator is used as a key management medium, and the method has the advantages of being novel, convenient, safe, reliable and low in cost.

Description

technical field [0001] The present invention relates to the technical field of blockchain digital asset key management management, in particular to a SIM card-based blockchain digital asset key management method and system. Background technique [0002] Currently, blockchain-based digital asset private key management is mainly based on hot wallets and cold wallets. The cold wallet stores the private key in an offline mobile electronic device or records it in other media, and is isolated from the Internet, so it has the highest security factor. There are two types of cold wallets in the market: one is chip-based cold wallets represented by LegderNano S, Trezor, and KeepKey. Even if the user loses the wallet or the device is stolen by hackers, the private key will not be lost, which can protect users The other is Android-based wallets represented by Kushen, Bepal, etc., also known as mobile wallets. The focus of this type of cold wallet protection is to isolate the hot and co...
