The invention discloses a block chain based key infrastructure
information management method. A decentralized shared data
pool, including, equipment foundation information, monitoring information, fault diagnosis and state overhaul scheme is built based on a block
chain network; and a just, fair and open key infrastructure
information management system is built. The method is to guarantee a creditfoundation in a sharing process by building a
consensus mechanism, to guarantee
information security in an information transaction process by adopting a public / private key
verification way and to improve participation enthusiasm of all parties involved by using a paid mechanism for jobs such as maintenance and evaluation of information in the data
pool. The block chain based key infrastructure
information management method can realize multi-
backup and multi-party supervision for a plenty of
data information of the equipment in the whole process from research and production, delivery for application to scrapping out of operation and can prevent
data loss and data
tempering or deletion caused by physical reasons; and as the platform which each party can participate in
data analysis and sharing, research work in all aspects of the key infrastructure is speeded up.
