Bluetooth utilizes a device pairing mechanism based on elliptic-curve Diffie-Hellman (ECDH) key exchange to allow encrypted communication between devices. The ECDH key pair consists of a private and a public key, and the public keys are exchanged to produce a shared pairing key. The devices must also agree on the elliptic curve parameters being used. Previous work on the "Invalid Curve Attack" showed that the ECDH parameters are not always validated before being used in computing the resulted…

An engineering and computer science professor and his team from The Ohio State University discovered a design flaw in low-powered Bluetooth devices that leaves them susceptible to hacking.
Zhiqiang Lin, associate professor of computer science and engineering at the university, found the commonly used Bluetooth Low Energy devices, such as fitness trackers and smart speakers, are vulnerable when they communicate with their associated apps on the owner’s mobile phone.
"There is a fundamental…
