Wireless Security

For Bluetooth device to pair with each other , they must first establish a 128-bit key that is used to encrypt all communication . in this way , no one can snoop on the devices and steal data , and no outside device can pose as one of the devices because outside devices don’t have the 128-bit encryption . both users of the devices that are to pair have to type in the same secret PIN , which is then used to create the 128-bit encryption key .

Here we outlined some of the basic steps to take to secure wireless networks in a small deployment. For home use, we recommend:
