#StackBounty: #bluetooth #replay-detection Freshness Protection in BL and BLE

Bounty: 100

I recently found this document: https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-121r2.pdf , Guide to Bluetooth Security from NIST.

Unfortunately, there is nothing described w.r.t.actual protection of the communication other than AES-CCM is used. I am asking myself wether the BLE (v.4.2) communication is actually secured against replay-attacks.


Get this bounty!!!
