The invention discloses an
electric power monitoring credible security operation and maintenance cooperation method,
system and device based on a block chain, and a storage medium, and relates to the technical field of
electric power monitoring, and the method comprises the steps: obtaining
sensing data of an
electric power monitoring terminal side, and carrying out the signature; in combination with the operation and maintenance instruction, block chain
consensus storage and
verification of the data and the instruction are carried out, the data and the instruction passing
verification are stored in a
sensing data chain and an operation and maintenance operation chain of the block chain, and
verification evidence is provided; acquiring a node historical behavior
data set, and performing dynamic trust value calculation and permission allocation; performing operation and maintenance instruction
compliance analysis and response in combination with a preset electric power
safety regulation logic
library, and generating a defense strategy set in combination with the
attack feature
library; the method guarantees the authenticity and integrity of data, and eliminates the forgery risk. The compliance verification time consumption is reduced from the hour level to the
millisecond level, the cross-department cooperation efficiency is improved, and the single-point fault and APT
attack risk is reduced; the manual auditing amount can be reduced, the accident
root cause can be quickly positioned, and the tracing requirement is met.
