    Abstract: A database access method and apparatus are disclosed, to ensure data security during interaction between a user and a database, and effectively reduce performance overheads. The method includes: receiving an encrypted data computation request sent by a database kernel, where the encrypted data computation request requests to perform computation on encrypted data of a user, and the database kernel runs in a non-secure execution environment; receiving encrypted data sent by the database kernel, where the encrypted data is all encrypted data in a user query request; performing decryption and computation on the encrypted data in response to the encrypted data computation request, to obtain a computation result; encrypting the computation result to obtain an encrypted computation result; and sending the encrypted computation result to the database kernel.

    Abstract: A client device configured to store data in a database of a data storage server is provided. The data storage server stores security sensitive data in one or more encrypted data structures of the database. The client device is configured to determine whether data to be stored in the database comprises security sensitive data to be stored in an encrypted data structure of the database and to encrypt this security sensitive data with an encryption key. Furthermore, the client device is configured to provide the data, including the encrypted security sensitive data, and an identifier of the encryption key to the server for storing, based on the identifier of the encryption key, the security sensitive data in the encrypted data structure of the database. According to the present disclosure, the security sensitive data which is already encrypted at the client device improves a secure protection of the data.
