Abstract

The invention relates to a method for managing non-volatile memory space in a secure processor comprising a secure non-volatile internal memory, the method comprising steps of: selecting data elements to remove from the internal memory, generating, by the secure processor, a data block comprising the selected data elements, and a signature computed from the selected data elements using a secret key generated by the secure processor, transmitting the data block by the secure processor, and storing the transmitted data block in an external memory.
