Invited Talk: BLERP: BLE Re-Pairing Attacks and Defenses

Bluetooth Low Energy is a widespread wireless technology connecting billions of gadgets, relying on a pairing process to generate secret keys for safe communication. Sometimes, previously connected equipment must negotiate a new security level through a procedure called re-pairing. Researchers discovered significant vulnerabilities within the official rules governing this re-pairing mechanism. Specifically, the standard lacks proper authentication checks and allows hackers to force connections i...
