A Cost-Effective Tag Design for Memory Data Authentication in Embedded Systems

This paper presents a tag design approach for memory data integrity protection. The approach is area, power and memory efficient, suitable to embedded systems that often suffer from stringent resource restriction. Experiments have been performed to compare the proposed approach with the state-of-the-art designs, which demonstrate that the approach can produce a memory data protection design with a low resource cost - achieving overhead savings of about 39% on chip area, 45% on power consumption, 65% on performance, and 12% on memory cost while maintaining the same or higher security level.
