The invention discloses a
blockchain-based intelligent
video monitoring data
storage security sharing method for an iron and steel
plant. The method comprises the following steps of: generating a public key PKS and a
master key TMK based on an attribute
encryption algorithm; distributing shares of the shared key S by constructing a matrix and defining a function, wherein the shares are distributed in different rows of the matrix; re-encrypting the data by using a
hybrid proxy re-
encryption algorithm based on a
ciphertext strategy; secure data storage and
access control are realized based on a secure storage mode of revocable attribute-based
encryption RABE and a block chain; and in combination with a block chain technology, a
consensus algorithm is adopted to verify transactions, so that the security and robustness of the
system are enhanced. According to the invention, the
utilization rate of the data is improved, the cooperation efficiency is enhanced, the security and transparency of the
video monitoring data are improved, and the cost of
information transmission and storage is reduced. The distributed storage and
access control of the data are realized, the
confidentiality and integrity of the cloud center data are ensured, and the security and efficiency of the steel
plant video monitoring system in the storage and transmission process are enhanced.
