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. 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.
