If the central device is ready to listen to the advertisement packets, it will respond with a scan response request. The peripheral device will send an advertising data once every 2 seconds. This illustrates how the advertisement and scan response payload work. Heart rate monitor is an example of a peripheral device.Ĭentral devices : These devices are mostly cell phones or gadgets that have an increased memory and processing power. Peripheral devices : These are small and low energy devices that can connect with complex, more powerful central devices. The following two concepts are integral to GAP: GAP is responsible for the visibility of a device to the external world and also plays a major role in determining how the device interacts with other devices. This is responsible for the connections and advertising in BLE.

Fuzzing attacks too lead to systems crashing as an attacker may send malformed or non-standard data to a device’s Bluetooth radio and check its response, ultimately overwhelming it. DoS attacks expose a system to the possibility of frequent crashes leading to a complete exhaustion of its battery.

Denial of Service & Fuzzing Attack: Since most wireless devices these days work on inbuilt battery packs, these devices run the risk of being exposed to Denial of Service Attacks (DoS).

This sort of an attack enables the attacker/impersonator to access all the data that is being exchanged between the devices and also, manipulate data by deleting it or changing it, before it reaches the respective device.

Man in the Middle Attacks (MITM): Man in the middle attacks involve a third party device impersonating a legitimate device, tricking two legitimate devices into believing that they’re connected to each other, when in reality, the legitimate devices are connected to the impersonator.

Once the PIN is derived, the device can easily be hijacked.

Even if the encryption/ decryption keys on the device were to be deleted, the attacker may brute force the PIN number offline using a Bluetooth Sniffer (using the ID of the device). An attacker may use the device unit number for getting access to other Bluetooth connected devices. The chain gets broken when one of the device is removed. A connection between two paired devices signifies a chain of trust.

Eavesdropping: As the name suggests, eavesdropping refers to a third party device listening in on the data that’s being exchanged between two paired devices.

Let us have a look at the three main vulnerabilities that BLE may expose its users to: While all Bluetooth Low Energy devices were developed with the principal motive of enhancing user experience, did security take a backseat during the process? Thus, it can be said that the security of BLE lies in the hands if its implementers.

Even the strongest cryptographic protocol has been known to fail due to the random number generator not being 'random enough.' The same applies to BLE.

It’s up to the manufacturers to implement BLE securely in their device. That’s a good question from a security standpoint.

Significantly lower implementation costsīLE does sound good but, is it really all that good?.

Helps maintain a connection for longer periods of time.

Enables multi-platformed communication: Can easily communicate via a large number of devices that run on Android, iOS, Linux, Windows Phone, Windows 8, and OS X.

BLE was conceived with an emphasis on better pairing speed and energy efficiency.

Nokia originally developed BLE for an in-house project called ‘WIBREE,’ which was later on, taken over by the Bluetooth SIG. From smartphones, smart televisions, advanced technologies such as medical equipment to a basic devices such as our coffee machines, all use BLE.

#DEFINE GENERIC BLUETOOTH ADAPTER TV#

BLE is perfect for a TV remote but not for a wireless media streaming device which needs a large amount of data to transmit.īluetooth Low Energy is built into many of the gadgets that we use today. This significantly reduces power consumption making it ideal to use in cases where a persistent long term connection is required with a low data rate. BLE is an 'always off' technology and only transmits short amounts of data when required. Compared to classic Bluetooth, BLE is intended to use lesser power while maintaining similar communication range. With the rapid growth of IoT accelerating development in Bluetooth technology, constant efforts are being taken by the Bluetooth Special Interest Group (SIG) to increase the transfer speed with a maximum focus on beacons, healthcare entertainment, and fitness.īluetooth Low Energy (BLE) is a part of the Bluetooth 4.0 specification which additionally also includes Classic Bluetooth and Bluetooth High Speed Protocols.

Bluetooth, as we know, is one of the most popular and widely used wireless technologies in today’s world.
