Abstract
The present invention relates to an electronic device () in which acceleration of data processing operations is provided, the device comprising a secure execution environment to which access is controlled. A basic idea of the present invention is to provide a device () for acceleration of data processing operations (an 'accelerator'). In particular, the accelerator is used to accelerate cryptographic data operations such that it performs cryptographic operations on data provided to it via a first logical interface. The cryptographic operations are performed by means of encryption/decryption keys provided to the accelerator via a secure second logical interface which may share a same physical interface () with the first logical interface or which may use a distinct physical interface () from that of a distinct physical interface () used as the first logical interface.
