Research on Key Technologies of High Value Certificate Depository Based on Decentralized Storage and Asymmetric Encryption

With the construction of modern (intelligent) supply chain and green modern digital intelligence supply chain, the digital capability of contract management business has been comprehensively improved, but the traditional information capability of letter of guarantee, margin and insurance business has effectively realized digital empowerment, and the bills such as guarantee and margin in the supplier service hall of electric power enterprises need to be checked and handled. The application of decentralized storage and asymmetric encryption technology can effectively ensure the correctness and integrity of data, and ensure the security and credibility of data. In this paper, combined with the business characteristics of the supplier service hall of power enterprises, we study the high-value certificate storage based on decentralized storage and asymmetric encryption technology, and innovate the use of VRF+BFT consensus algorithm, RSA asymmetric encryption algorithm and overlapping network transmission optimization algorithm, so as to create a secure, efficient and trusted application of high-value certificate storage for the supplier service hall.
