Disclosed herein is a method of accessing a cache, the method comprising: mapping respective physical line addresses (PLAs) of a plurality of PLAs to respective cache locations of a plurality of cache locations in a cache, each PLA of the plurality of PLAs having an associated memory line; encrypting, with a block cipher using a first key, a first PLA of the plurality of PLAs to provide a first encrypted line address (ELA), the first ELA having an associated first encrypted cache location; upon receiving a request to access a first memory line associated with the first PLA, encrypting, using the first key, the first PLA into the first ELA to determine the associated first encrypted cache location; and accessing the first encrypted cache location. Also disclosed herein are systems for implementing the same.
