The present invention provides a transmission method for file multi-layer encryption, comprising: encrypting a to-be-transmitted file in an encryption end; generating one or multiple decryption password files for the encrypted file; encrypting each of the generated decryption password files; and generating one or multiple decryption passwords for the encrypted decryption password files, so as to realize multi-layer encryption of the to-be-transmitted file; first decrypting the encrypted decryption password files in a decryption end, and then decrypting the encrypted file, so as to realize multi-layer decryption of the to-be-transmitted file, thereby ensuring file transmission security. Also provided are an encryption end and a decryption end applied to the method. |
