According to the two types of identity mapping in existed IBE schemes: one type is GPV-IBE [1] and another is other lattice-based IBE schemes [2–7], there are two types of vector ciphertexts in original IBE schemes and hence two types of matrix ciphertexts in dual-Regev encryption form of [8,9]. The ciphertext expansion technique in identity case is to expand the matrix ciphertext under a secret key sidi = (1,w T idi )T
