The present application relates to the technical field of block chain, and particularly relates to a kind of identity authentication encryption method based on block chain node user, comprising the following steps: step 1: build user identity information database, obtain user identity information data in database storage;Step 2: traversing reading the user identity information data stored in database, extract character data in the user identity information data stored in database, and apply character data to build the encryption database used when user is authenticated on block chain node;The method in the present application further constructs the key database with the identity information of the user on the basis of the encryption algorithm used when the existing block chain node user is authenticated in the process of executing its steps, so that the further encryption of the key database constructed is applied when the block chain node user is authenticated, so that the block chain node user is more secure when being authenticated.

The application discloses a data encryption method and device. The method comprises the following steps: obtaining a first target time, a target place and to-be-encrypted data in input parameter data; selecting an arbitrary time before the first target time as an offset time from a historical time period; generating first offset information based on the offset time and the target place; obtaining an environmental information array of the target place in the offset time, and combining a plurality of target environmental variables selected from the environmental information array to generate a key; and encrypting the to-be-encrypted data based on the first offset information and the key. The application solves the technical problem of data leakage caused by the fact that the prior art cannot provide more reliable encryption for data.
