| Abstract(in English) | Identity-based Encryption with Equality Test (IBEET) is an extension of identity-based Encryption (IBE) that can check the plaintext equality of two distinct ciphertexts. Thus far, known lattice-baesd IBEET schemes do not purely satisfy adaptive security and CCA security, simultaneously. In this paper, we propose the first adaptive and CCA-secure lattice-based IBEET schemes. Moreover, the proposed schemes based on Yamada's scheme and Jager-Kurek-Niehues's scheme have shorter public keys than known adaptive and CPA-secure schemes. |
