The invention provides an information operation and maintenance service
knowledge sharing method based on trusted computation of
big data. According to the method, a trusted degree assessment mechanism and a trusted relationship
transfer mechanism are built on the basis of characteristics such as protective function,
authentication,
integrity measurement and the like; the method comprises steps as follows: secure storage of information operation and maintenance knowledge, secure access of information operation and maintenance knowledge as well as trusted evaluation, wherein the secure storage of the information operation and maintenance knowledge comprises following steps: (1), performing security
verification on an identity of a stored user; (2), preprocessing information operation and maintenance service knowledge data; (3), performing encoding; (4), performing abstract concentration on hardware storage resources, mapping the resources to an integrated and unified
resource pool, and virtualizing a user
operating system; (5), storing the information operation and maintenance service knowledge data into the
resource pool in a final code form; the secure access of the information operation and maintenance knowledge comprises following steps: (1), performing security
verification on an identity of an access user; (2), reading the information operation and maintenance service knowledge data stored on the
resource pool. With the adoption of the method, barrier-free sharing can be realized,
memory footprint is reduced, the data calling speed is increased, and the security of information operation and maintenance service
knowledge sharing is improved on the premise that the convenience is guaranteed.
