Bluetooth pairing vulnerability

PaKa

The Bluetooth SIG released an errata for the 4.2 and 5.0 versions of Bluetooth specification on July 23rd relating to a potential vulnerability with the pairing procedures.

For Bluetooth low energy; this only impacts the low energy secure connections mode of pairing, or LESC. LESC is using Diffie Helman key exchange and the potential vulnerability has to do with key validation not bein a mandatory feature in the previous releases of the specification.

 

Nordic Semiconductor is taking security very serious and we already mitigated this attack in the nRF5 SDK release 15 back in March 2018.

  • I don't know how to explain it but recently our system administrator said that in the office security management data should be sent over the L2CAP security management channel. The security management protocol provides the user interface via the GAP layer. The user sets input and output capabilities and device pairing parameters. How am I supposed to set this up, I don't understand anything, because I'm a writer and I'm just providing coursework writing help to https://writemypapers4me.net/coursework-help/. Now I have to learn it, and here I am reading this forum.
