Summary:
Identity-based encryption with non-interactive opening is an extension of identity-based encryption which allows a receiver to prove a given ciphertext will be decrypted to a public message without revealing his decryption key. Fan et al. (J. Shanghai Jiaotong Univ. (Sci.)) proposed a construction of this primitive. We analyze the security of their scheme and show that the scheme is in fact not secure.
