Abstract

A computer operates on confidential data that are organized in finite-sized data chunks. First, each said data chunk is assigned a particular logical address of a set of logical addresses. Next, each data chunk is stored at a respective unique physical address on a medium, whilst maintaining a predetermined relationship between the particular logical address and the unique physical address. Next, a computer software program accesses the chunks through the logical addresses. A representation of predetermined relationship is read. In particular, before storing, a data chunk is encrypted through an encryption key that is at least co-based on an address assigned to the data chunk. After reading , a data chunk is decrypted through usage of a decryption key as an inverse of the latter encryption key. The chunks may or may not be uniform-sized.
