Abstract With the growing popularity of cloud computing, cloud storage service becomes an essential part of cloud services and numerous researches have been widely studied in recent years. Recently, Hsu et al. proposed an ElGamal-based simple keyword search scheme over encrypted data in cloud storage services. They claimed that a secure cloud storage service needs to achieve five security requirements, including: consistency, ciphertext indistinguishability, trapdoor indistinguishability, outside keyword guessing attack and inside keyword guessing attacks. However, in this paper, we observe that Hsu et al.’s scheme not only cannot prevent inside keyword guessing attack but also cannot prevent denial of service attack and has low efficiency problem in computing algorithms.
