Oil and gas field data security protection method and system

Abstract

The invention relates to the field of oil and gas field data safety, in particular to an oil and gas field data safety protection method and system. Obtaining a secret key; acquiring a shift distance according to the data packet length; obtaining XOR operation data according to the packet length; generating key streams according to the keys and grouping the key streams; obtaining an encryption method of each group of key streams according to the shift distance in combination with an XOR operation; obtaining an encryption round of the key stream packet according to the data generation time period; and encrypting each group of key stream groups in combination with the encryption rounds and the encryption method to obtain key streams, and encrypting the oil and gas field data according to the key streams. According to the method, the RC4 encrypted oil and gas field data is safer under the condition that the key does not need to be changed frequently.
