Abstract
A monotonic counter implemented at least in part in non-volatile memory hardware is described herein. Compared with software counting algorithms, the disclosed embodiments significantly enhance security of disclosed monotonic counters. In some aspects of the disclosed embodiments, a non-binary coded decimal (BCD) counting algorithm can be utilized in whole or in part to enhance longevity of non-volatile memory cells storing monotonic counter values. Various aspects of the present specification disclose both a monotonic increase counter, and a monotonic decrease counter.
