The Bluetooth SIG Focuses on Security
The Bluetooth SIG is constantly improving formats for combating security threats associated with Bluetooth technology. Offering a secure method to wirelessly communicate has always been one of the key benefits of Bluetooth technology. If you look at The History of Bluetooth, you will see that offering secure data transmission was one of the core principles for its creation.
In order to lead the security effort, a group of engineers within the Bluetooth SIG formed the Bluetooth Security Experts Group. As the Bluetooth Core Specification Versions continue to advance, the Bluetooth Security Experts Group is responsible for monitoring the advancement and testing for flaws in its security.
The Fundamentals of Bluetooth Security
One of the most basic levels of security for Bluetooth devices is the “pairing” process.
Pairing = Two or more Bluetooth devices recognize each other by the Bluetooth Profiles they share, and in most cases, both must enter the same PIN.
The Bluetooth core specifications use an encryption algorithm, which is entirely secure. Once Bluetooth devices pair with one another, they too are entirely secure.
Bluetooth devices will not communicate with each other until they have successfully paired. So, because of this pairing process and the fact that it has a short range, Bluetooth technology is considered to be fundamentally secure.
Unfortunately, as recent news has indicated, experienced hackers have come up with a way to get around this basic level of security. However, there are precautions users can take to limit the chances of their Bluetooth device from being compromised by a hacker.
