ENCRYPTION PPT PRESENTATION.ppt ENCRYPTION PPT PRESENTATION.ppt Presentation Transcript

  • ENCRYPTION By Group 3 Karilyn Lao, Richman Lo, & Robert Mastronardi
  • What is encryption?
    • A process that converts original information, also called plain text into a difficult-to-interpret form called ciphertext.
    • Done by using an encryption algorithm, a formula used to turn plain text into ciphertext.
    • Two types: Asymmetric and Symmetric
  • Asymmetric Encryption
  • Symmetric Encryption
  • Which one is better?
    • Although, symmetric encryption is fast, it is not as safe as asymmetric encryption because someone could “steal” the key and decode the messages. But because of its speed, it's commonly used for e-commerce transactions.
    • Asymmetric encryption is more complex--and more secure. Asymmetric encryption's added safety comes at a price: More computation is required, so the process takes longer.
  • Who’s using encryption?
    • If you use a computer and the internet, you’re using encryption!
    • Enables all organizations regardless of their size, to be both user-and-IT friendly.
  • Why use encryption?
    • Authentication
        • Protects personal data such as passwords.
    • Privacy
        • Provides for confidentiality of private information.
    • Accountability
        • Prevents denial or plagiarism.
    • Integrity
        • Ensures that a document or file has not been altered.
  • How do you manage encryption?
    • Make sure the encryption system has a complete key management application.
        • This will help manage and protect the data and keys, and help you safely match encrypted data with the right key.
  • Examples of Encryption
    • Web browser encryption
    • Email encryption
    • Hard drive encryption
    • Operating system protection
  • A few vendors and their product coverage
    • Blackberry
        • System, software, hardware, and service.
    • Global Technologies Group, Inc. (GTGI)
        • Software and hardware.
    • Hewlett-Packard Company
        • System, software, hardware, and service.
    • Intellect Security Ltd.
        • Software
  • How prevalent is it?
    • According to InformationWeek Research:
        • Of 500 sites surveyed, two-thirds report using encryption to protect company data.
        • Of 500 companies surveyed, 43% use encryption on both stored and transmitted data. More than three out of five companies encrypt due to the threat of outsiders intercepting sensitive data.
    Continued…
        • Of 28% of sites surveyed, government regulation requires encryption of stored and transmitted data.
        • For 38% of companies, the complexity of the technology is an obstacle.
        • Some businesses aren’t able to use the technology because of the lack of skilled IT personnel and budget limitations.
