Questions and Answers

What is the primary goal of WEP in WiFi security?

  • To provide authentication for users
  • To provide data confidentiality similar to a wired network (correct)
  • To encrypt data using the AES cipher
  • To improve the speed of WiFi connections

    • What is the encryption method used by WEP?

  • RC4 (correct)
  • MD5
  • AES
  • SHA-256

    • What is the main problem with WEP's use of the RC4 cipher?

  • The cipher is too slow
  • The starting variables must be unique, but are easily duplicated (correct)
  • The cipher is not widely supported
  • The cipher is too complex

    • How many distinct possibilities are there for 24-bit starting variables in WEP?
