Data integrity auditing method based on block trust election mechanism in edge computing

The invention requests to protect a data integrity auditing method based on a block trust election mechanism in mobile edge computing, which belongs to the field of mobile edge computing and comprises the following main steps: S1, an edge terminal divides data according to a Fibonacci sequence and then uploads the data; s2, calculating the objective weight of each index of the edge server based on a CRITIC weight method; s3, on the basis of a TOPSIS evaluation method and the objective weight of each index of the edge server, calculating the quality value of each scheme; s4, the storage server carries out data occupancy proof and storage information storage based on a Merkel tree of a Hungman tree structure; and S5, the auditing server inquires the specified file stored in the storage server, and obtains an auditing result by auditing the Schnorr signature of the Merkel tree node. According to the method, a server election mechanism is introduced, so that the reliability of data integrity auditing is improved,
