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.
