Overview

3. • An embedded system is a combination of computer hardware and
software, either fixed in capability or programmable, that is specifically
designed for a particular function.
Embedded System

4. • Network security is a term that describes the policies and procedures
implemented by a network administrator to avoid and keep track of
unauthorized access, exploitation, modification and denial of the access.
Network Security

5. • Hacking is gaining of unauthorized access to a computer and viewing,
copying, or creating data with/without the intention of destroying data or
maliciously harming the computer.
Hacking

6. Reasons for Hacking:
Cost of Insecurity:
Survey

7. • Advancement in Technology
• Security is an afterthought
Problem Definition

8.  Hardware approach :
It uses ASICs
(Application Specific Integrated Circuits)
to implement a given cryptography
algorithm in hardware.
 Hybrid Hardware - software approach :
It uses a general purpose embedded processor
and integrates hardware accelerators for the
execution of critical Cryptographic algorithms.
Proposed Solution

9. Comparison
Existing Solution
(Software Solution)
Proposed Solution
(Hardware Solution)
• Protects the system against software
attacks only.
• Protects the system against software
as well as hardware attacks.
• Has to be administered by the user. • Self – administered.
• It proves to be expensive. • It is cost effective.
• Updating on a regular basis needs to
be carried out.
• Eliminates the need for updating.
• High level user interaction required. • User interaction is close to nil.

10.  Design challenges:
 Battery Gap
 Flexibility
 Tamper resistance
 Interaction between Network Security engineer
and Architecture engineer is required.
 Presently it is difficult to implement in the
existing devices.
Disadvantages of the Proposed solution

11. • Development in the semiconductor industry might aid the manufacturing
of the chip.
• Diversity in the hardware component used(Cryptographic Chip).
• Develop methodology to provide the features of Cryptographic chips in
the existing devices.
