Question

A wired equivalent privacy (WEP) key for a wireless fidelity (WiFi) network is a string of either 10, 26, or 58 hexadecimal digits. How many different WEP keys are there? (There are 16 place values for hexadecimal numbers: 0 to 9, A, B, C, D, E, and F.)

Answer 1

The total number of ways are:
`16^(10)+16^(26)+16^(58)=6.9017463468*10^(69)`.

Explanation:

Consider the provided information.

It is given that there are 16 hexadecimal numbers.

If the length of the string is 10 then we have 10 place and 16 digits for each place.

Therefore, the number of ways are:

`16* 16* 16* 16* 16* 16* 16* 16* 16* 16 =16^(10)`

Similarly, the number of possible WEP keys with 26 digi is:
`16^(26)`

Similarly the number of possible WEP keys with 58 digi is:
`16^(58)`

The total number of ways are:
`16^(10)+16^(26)+16^(58)=6.9017463468*10^(69)`.
