Abstract

A device securely accesses data in a memory via an addressing unit which provides a memory interface for interfacing to a memory, a core interface for interfacing to a core processor and a first and second security interface. The device includes a security processor HSM for performing at least one security operation on the data and a remapping unit MMAP. The remapping unit enables the security processor to be accessed by the core processor via the first security interface and to access the memory device via the second security interface according to a remapping structure for making accessible processed data based on memory data. The device provides a clear view on encrypted memory data without requiring system memory for storing the clear data.
