(Ping! Zine Digital Issue 04) – Bluetooth has grown a bit more recently. Bluetooth released a new version recently. But instead of going from 2.0 to 3.0, it went from 2.0 to 2.1. Now what has changed in Bluetooth to merit a .1 change in the version? 2.1 has a few new features that make it stand apart from 2.0. First there is SSP (Secure Simple pairing), second is EIR (Extended Inquiry response), third is a more secure data transfer, and finally better power usage. These new innovations in Bluetooth are setting the ground work for Bluetooth 3.0.
SSP connects to a device through four methods: Just Works, Numeric Comparison, Passkey Entry and Out of Band. Just Works technology works just as it sounds. It just works. The user does not have to do anything other than put the devices being paired into pairing mode, and either put them close together or touch them together. The only thing the user may have to do is confirm the pairing, but otherwise a PIN is not required. Just Works also protects from man in the middle (MITM) attacks. MITM attacks are where a third party will intercept communication between devices and can steal information from unsuspecting users. Also MITM attacks allows the third party to intercept messages and supply false messages.
