Power big data transmission method and system based on fast matching and integrity detection

Abstract

The invention discloses a power big data transmission method and system based on rapid matching and integrity detection. The power big data transmission method comprises the following steps: acquiring digital fingerprints mapped by data packets; performing encryption to generate ciphertexts, adding the digital fingerprints to the tails of the ciphertexts, and storing the ciphertexts in the cloud terminal; transmitting request data; receiving and feeding back request response data; encrypting the data packets according to the fed-back request response data to generate ciphertexts, and transmitting the ciphertexts; decrypting the received ciphertexts to obtain the digital fingerprints; performing rapid matching, and acquiring the digital fingerprints according to a calculated matching degree; judging whether data packets required by a user exist in cloud storage or not; if the data packets exist, transmitting the data packets after packaging; performing decryption, re-calculating the digital fingerprints of the data packets, and comparing the digital fingerprints with the digital fingerprints above; and judging whether the digital fingerprints are consistent or not according to a comparison result: if the digital fingerprints are consistent, performing a judgment to obtain a result indicating that the data packets are not modified. Through adoption of the power big data transmission method and system, safe and efficient transmission of power big data can be realized; the integrity of the data in a transmission process is ensured; and the data transmission speed is increased.
