ABSTRACT:
A method for protecting data between a circuit and a memory is disclosed. The method generally includes the steps of (A) generating a particular address among a plurality of addresses for accessing a particular area among a plurality of areas in the memory, (B) determining a particular key among a plurality of keys associated with the particular area, (C) generating a cipher stream from both the particular address and the particular key and (D) modifying a data item with the cipher stream such that the data item is encrypted during a transfer between the circuit and the memory.
