Also Available Domains Communications|Xilinx Vivado
Objective
The main objective of this paper is to reduce the error rate and power in encrypted data encoded by the Advanced Encryption Standard. This paper is implemented with the randomness feature of AES encryption as well as rotational shift operation to tolerate hard faults in nonvolatile memory cells
Abstract
In this paper, we present a simple, yet energy-
and area-efficient method for tolerating the stuck-at faults caused by an endurance
issue in secure-resistive main memories. In the proposed method, by employing
the random characteristics of the encrypted data encoded by the Advanced
Encryption Standard (AES) as well as a rotational shift operation, a large number
of memory locations with stuck-at faults could be employed for correctly
storing the data. The proposed RandShift technique, which is simple and energy
efficient due to its one-time recomputation of the AES encryption for each data
written to the PCM main memory. Due to the simple hardware implementation of the
proposed method, its energy consumption is considerably smaller than that of
other recently proposed methods. The fault coverage of the proposed method is
similar to that of the existing method. In this article, we present a simple
energy-efficient method to tolerate the stuck-at faults in the PCM main memory
when encrypted data are stored on it.
