00:00:01,190 --> 00:00:09,380
So let's have a look at Wi-Fi protected setup or what you might see as WPX, sure, it's a standard

2
00:00:09,380 --> 00:00:17,120
for the easy and secure establishment of a wireless network that weps is an optional certification program

3
00:00:17,120 --> 00:00:18,980
for Wi-Fi certified products.

4
00:00:20,000 --> 00:00:26,840
So not all wi fi certified products will include some sort of support.

5
00:00:27,990 --> 00:00:35,970
Users will need to look for the Wi-Fi protected set logo or, you know, some equivalent term on the

6
00:00:35,970 --> 00:00:40,490
product to ensure that the product is WPX compatible.

7
00:00:41,310 --> 00:00:51,580
So WPX automatically configures a network name, SS ID and a security key for the access point and the

8
00:00:51,620 --> 00:00:55,580
WPX enabled client devices on a network.

9
00:00:56,790 --> 00:01:02,610
You don't need to know the SS IDs and security key or even the passphrase when connecting waps enabled

10
00:01:02,610 --> 00:01:03,150
devices.

11
00:01:04,500 --> 00:01:11,310
No one can guess or figured out your security key or passphrase because the keys will be randomly generated

12
00:01:11,700 --> 00:01:18,060
so there's no predictable passphrase or long sequences of hexadecimal to enter.

13
00:01:20,440 --> 00:01:27,400
Now, information and network credentials are securely exchanged over the air using the Extensible Authentication

14
00:01:27,400 --> 00:01:28,990
Protocol, or IAP.

15
00:01:29,950 --> 00:01:33,400
That's one of the authentication protocols used in WPA to.

16
00:01:34,810 --> 00:01:38,200
However, yes, there are a few disadvantages.

17
00:01:39,530 --> 00:01:46,850
One, it doesn't support ad hoc mode or network where wireless devices are communicating directly to

18
00:01:46,850 --> 00:01:48,770
each other without an access point.

19
00:01:49,600 --> 00:01:59,290
And all of the Wi-Fi devices on the network must be certified or GPS compatible, otherwise you won't

20
00:01:59,290 --> 00:02:03,810
be able to take advantage of the ease of securing the network in this way.

21
00:02:05,360 --> 00:02:10,110
Now, there are three primary methods used and Wi-Fi protected set up.

22
00:02:10,640 --> 00:02:16,280
There's a pin entry push button configuration and near field communication.

23
00:02:18,100 --> 00:02:24,220
In all Wi-Fi protected setup networks, a unique pin will be required for each device to join the network.

24
00:02:26,090 --> 00:02:33,920
A fixed PIN label or sticker may be placed on a device or a dynamic pin can be generated and then shown

25
00:02:33,920 --> 00:02:35,420
on the devices display.

26
00:02:36,480 --> 00:02:43,200
In any event, the pen is used to make sure the intended device is added to the network being set up,

27
00:02:43,500 --> 00:02:51,000
and it'll help to avoid accidental or even malicious attempts to add unintended devices to that network.

28
00:02:52,210 --> 00:02:58,300
And when some Wi-Fi protected set up networks, the user may connect multiple devices to the network

29
00:02:58,300 --> 00:03:01,990
and then enable data encryption by pushing a button.

30
00:03:03,440 --> 00:03:10,910
The access point, or wireless router, will have a physical button and other devices may have a physical

31
00:03:10,910 --> 00:03:12,580
or even a software base button.

32
00:03:14,560 --> 00:03:19,270
And then during the usually two minute set up period, which follows the push of that button.

33
00:03:20,230 --> 00:03:27,550
Unintended devices could join the network if they are in range, and finally, a near field communication

34
00:03:27,550 --> 00:03:35,800
interface or an NFC can be used to transfer network settings to a new device without requiring manual

35
00:03:35,800 --> 00:03:36,790
entry of its PIN.

36
00:03:37,720 --> 00:03:44,950
Make a note, the NFC method provides strong protection against adding an unintended device to the network.

37
00:03:46,430 --> 00:03:48,470
But I'll leave that as a dot, dot, dot.
