What is encryption?

• Process whereby data is encoded or scrambled to
  make it unintelligible to eavesdroppers and the
  data is decoded or converted back to its original
  form by means of a key available only to the
  intended recipient of that data. (p.224
  Cyberethics)

3
Types of Encryption

• Symmetric Key
• Secret Code
• Public Key
• PGP Pretty Good Privacy
• DES
• Data Encryption Standard
• AES
• Advanced Encryption Standard

Rijndael, a new algorithm

• An AES algorithm chosen by the Federal
  Information Processing Standard (FIPS), a US
  Government organization.
• Created by cryptographers from Belgium Dr. Joan
  Daemen (Yo'-ahn Dah'-mun) of Proton World
  International and Dr. Vincent Rijmen (Rye'-mun),

5
Why Rijndael?

• Rijndael's combination of security, performance,
  efficiency, ease of implementation and
  flexibility make it an appropriate selection for
  the AES.
• DES takes a matter of hours to break, while
  128-bit AES encryption takes over 149 Trillion
  years.
• The Universe is only 20 billion years old!!!
• Example of Rijndael Algorithm

Common Usage

• Private communication
• Personal details
• Credit-card numbers
• Social Security number
• Bank Account Info.
• Confidential Company information
• Military/Governmental

7
Professional/Social Issues

• Criminal Activities
• High tech crimes, i.e. stolen private
  information.
• Terrorism
• Secure communication between sects.
• Helps keep private information secure
• Companies and individuals both benefit, i.e.
  online transactions.

8
Legal/Policy Issues

• The First Amendment!
• Right to keep sensitive information private.
• Right for government to defend national security.

9
Ethical Issues

• Right to conceal ones information.
• What I do in my spare time is none of your
  business.
• Then again, maybe for the greater good, my
  information should not be encrypted.
• Ethical Egoism

10
Stakeholders

• Governments
• Individuals
• Companies
• Criminals

11
Possible actions

• No encryption for anyone
• Government regulated encryption
• No encryption regulations at all

12
Consequence No Encryption

• No privacy
• Lack of trust in internet
• E-commerce
• Communication (Email, IM, etc)
• No security
• Sensitive Government information at risk
• Corporate information exposed

13
Consequence Government Regulated Encryption

• Secure information for government.
• Government allows encryption for the people, but
  can decrypt it when necessary.
• Cracks down on crimes and keeps tabs on
  terrorism.

14
Consequence No Standard

• Individuals can keep information to themselves.
• Government security issues.
• Private sectors will be more secure.
• Lengthen the decryption process when dealing with
  foreign algorithms.

15
Individual Rights

• No encryption
• Loss of privacy
• Government Regulated
• Limited privacy
• No regulations
• Max privacy

16
Common Good

• No Encryption
• Freedom of access to all information.
• However, lacks protection, a double edge sword.
• Government Regulation
• Safety for all.
• No Regulations
• Privacy for all.
• Advancement of technology.

17
Final Decision

• We choose No Regulations
• The perceived safety from Governmental Regulation
  is not worth the sacrifice of individual rights.
• THE END?
