| Summary: | This report presents a framework for generating a memory integrity tree to
demonstrate the success of securing untrusted memories in embedded systems with
dynamic integrity checking. The development is a follow-up work of a previous student
in Year 2015 which has developed a C-language program for memory authentication
using TEC-Tree on an embedded system implemented on NIOS II Processor.
Analysis is first carried out on the previous work/ program to identify the limitations
and constraints. The main focus of this project is to create a framework to automate the
generation of an efficient TEC-Tree. This efficient tree allows the flexibility to have any
number of data while removing redundancy. In addition, the proposed framework can
generate trees of varying bit-size as well as enabling any number of children for each
parent node of the tree in order to increase the efficiency.
The code/ program development work is based on C-language and the embedded
system using NIOS II Processor. Experiments are performed and results are analyzed to
determine the efficiency of the new code/ program in term of timings for Read and
Write functions as compared to previous project. |
