Big data network security data transmission method

The invention relates to the field of data encryption transmission, in particular to a big data network security data transmission method, which comprises the following steps of: collecting log data set information of attacked websites and performing standardization processing to obtain a standardized data set; extracting log data information features of each piece of data in the data set; grouping the data set according to the attack object to obtain each data group; for the data of each data group, carrying out weight distribution based on information features of a timestamp, an attack source and an attack mode of the data to obtain voting weights corresponding to the information features; performing data weighting on each data group by using the voting weight to obtain weighted data information, and further obtaining a weighted data information set; and according to the weighted data information set, all the data groups are layered, each layer is encrypted, and encryption modes of different layers are diff
