Block chain chip cryptographic algorithm encryption and decryption method

Abstract

The invention provides a block chain chip cryptographic algorithm encryption and decryption method, and relates to the field of encryption and decryption methods. The block chain chip national cryptographic algorithm encryption and decryption method comprises a user side, a terminal and an encryption unit, and is characterized by comprising the following steps that: S1, the user side selects encryption transmission or ordinary transmission: if encryption transmission is selected, data transmitted by the user side is sent through a selection channel I, and is encrypted through the encryption unit; if common transmission is selected, the data transmitted by the user side is sent through the second selection channel, and the terminal receives the data. The information is subjected to double encryption and is not easy to crack, the information can be looked up through a terminal or other user sides, the information lookup is more convenient, the information lookup needs to be permitted by a user who uploads the data, the user who uploads the data can find that the information is looked up at the first time, the secrecy capability is strong, the encryption unit is independently placed, the slave terminal cannot physically crack the encryption unit, which is more reliable.

Description

technical field [0001] The invention relates to the technical field of encryption and decryption methods, in particular to an encryption and decryption method of a blockchain chip national secret algorithm. Background technique [0002] The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected, and interacted, and its sound, Various information needed for light, heat, electricity, mechanics, chemistry, biology, location, etc., blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. When blockchain technology is u...
