Breaking the Bluetooth Pairing – The Fixed Coordinate Invalid Curve Attack
Bluetooth elliptic curve cryptosystem Diffie-Hellman
2019/9/19
Bluetooth is a widely deployed standard for wireless communications between mobile devices. It uses authenticated Elliptic Curve Diffie-Hellman for its key exchange. In this paper we show that the aut...
The specification of Bluetooth and Bluetooth Low Energy includes dedicated encryption key negotiation protocols used by two parties to agree on the entropy of encryption keys. In this work, we show th...
Bypassing Passkey Authentication in Bluetooth Low Energy
cryptographic protocols Bluetooth Low Energy Authentication
2014/3/12
This memo describes new cryptographic weakness of the passkey-based pairing of Bluetooth Low Energy (also known as Bluetooth Smart). The vulnerability discussed here extends the set of possible attack...
Comparison-Based Key Exchange and the Security of the Numeric Comparison Mode in Bluetooth v2.1
Comparison-Based Key Exchange Security Numeric Comparison Mode
2009/6/11
In this paper we study key exchange protocols in a model where the key exchange takes place
between devices with limited displays that can be compared by a human user. If the devices
display the sam...
A Uniform Framework for Cryptanalysis of the Bluetooth E0 Cipher
Uniform Framework Cryptanalysis Bluetooth E0 Cipher
2009/1/23
In this paper we analyze the E0 cipher, which
is the encryption system used in the Bluetooth specification.
We suggest a uniform framework for cryptanalysis of the
E0 cipher. Our method requires 12...

Stream cipher Cryptanalysis Bluetooth BDD
2008/10/31
In this paper we analyze the E0 cipher, which is the cipher
used in the Bluetooth speci¯cations. We adapted and optimized the Bi-
nary Decision Diagram attack of Krause, for the speci¯c de...
