摘要
In order to avoid the risk of theft and loss of the private key of the blockchain wallet, a novel secure and stable blockchain multi-party signature system combining software and hardware is proposed. First, at the software level, multi-party key management method is adopted to divide the blockchain wallet key into multiple fragments for multi-point storage. Threshold signature technology is adopted to provide key escrow and retrieval services. Then a cold wallet for storing keys is designed at the hardware level. In order to avoid the risk of being attacked by hackers through network contact, a visible light communication method based on Quick Response Code is proposed. The Base45 coding scheme is adopted to improve the coding efficiency of QR Code, and the GG18 multi-party signature process is optimized. Finally, this paper analyzes the security of visible light communication, and verifies the efficiency of this method by experiments.
