An apparatus including memory access circuitry for controlling access to data stored in the non-trusted memory, and memory security circuitry to verify integrity of data stored in the non-trusted memory. The memory security circuitry has authentication code generation circuitry for generating authentication codes to be associated with the data stored in the non-trusted memory, for use when verifying the integrity of the data. The apparatus also has a trusted storage, and the authentication code generation circuitry is arranged to generate different authentication codes, dependent on whether the authentication code is to be stored in the non-trusted memory or the trusted storage.
