Security issues have played a major role in the invention of Bluetooth technology. The Bluetooth SIG has
put much effort into making Bluetooth a secured technology. Several security measures have been
implemented at different protoc

Bluetooth technology has been considered as a cheap, reliable, and power efficient replacement of cables
for connecting electronic dev
There are three main steps in Bluetooth security procedures, which are as follows
Authentication: It involves proving the identity of one Piconet device to another. The
objective of the authentication procedure is to determine the client's authorization
In addition to these modes, there are also four different security modes that a device can implement.
These are as follows
Non-secure: The Bluetooth device does not initiate any security measures.
Service-level enforced security mode: Two Bluetooth device
Since there are now billions of Bluetooth devices in use, malicious security violations are common events
now and it is expected to increase in the near future. On the contrary, the increased usage of Bluetooth
devices makes security concerns even more al
With each release of a new Bluetooth version, the manufacturers have upgraded different aspects of this
technology to make it more secure and user-friendly to support a wide range of devices, a list of all the
Bluetooth versions released to date is mentio
Bluetooth security is based on building a chain of events. None of these events provides any meaningful
information to an eavesdropper. All the events must occur in a specific sequence for the enforcement of

The protocols below the host controller interface (HCI) are built into the Bluetooth microchip and the
protocols above the HCI are included in the host device's software package. The HCI ensures a secured
communication between the host and the Bluetooth m
A synchronous connection oriented (SCO) link is established to emulate circuit switched connections for
voice and data connection. While an asynchronous connection link (ACL) is defined for the data bursts.
This link also supports broadcasting and data ra
Bluetooth technology has become an integral part of this modern society. The availability of
mobilephones, game controllers, Personal Digital Assistant (PDA) and personal computers has
made Bluetootha popular technology for short range wireless c
