This document summarizes a technical seminar on security in embedded systems. It begins by defining an embedded system and network security. It then discusses reasons for hacking and a survey of security issues. It proposes both a hardware and hybrid hardware-software solution to security challenges and compares the proposed solutions to existing software solutions. Finally, it discusses future scopes like developing cryptographic chips and integrating security features into existing devices.

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.
