Blockchain-based electronic performance letter encryption transmission method and system

Abstract

The application provides a blockchain-based electronic guarantee encryption transmission method and system, the method comprises the following steps: obtaining electronic guarantee information transmitted by an electronic guarantee issuing party, initializing all nodes in a blockchain and generating keys to obtain a key set; encrypting the electronic guarantee information based on the key set to obtain a ciphertext hash address; connecting the ciphertext hash address and the key set to the blockchain, and transmitting the ciphertext hash address and the key set to an electronic guarantee receiving party through the nodes in the blockchain; and decrypting the ciphertext hash address through the key set to obtain decrypted electronic guarantee information. The application can effectively resist internal threats and reduce the risk of data theft by using a threshold decryption method, can effectively prevent data tampering and forgery, improve the security and credibility of data, and effectively solve the problems of long transmission delay and data redundancy.
