The invention discloses a method for NTRU-type fully-homomorphic encryption on an LWE circle. After parameters are defined, a partially-homomorphic encryption process is carried out and then steps such as a fully-homomorphic encryption process requiring no starting and the like are carried out Through secret-key switch and module switch technologies, addition encryption and multiplication encryption are applied in an encryption process. Noises of output ciphertext are smaller than noises of input ciphertext so that a role of ciphertext update is played and realization efficiency is higher because a starting process is saved. Therefore, the fully-homomorphic encryption method requiring no starting is realized with a high encryption efficiency and comparatively shorter acquired ciphertext.
