| dc.description.abstract | Bluetooth devices are being used very extensively in today's world. From simple
wireless headsets to maintaining an entire home network, the Bluetooth technology
is used everywhere. However, there are still vulnerabilities present in the pairing
process of Bluetooth which leads to serious security issues resulting in data theft and
manipulation. We scrutinize the passkey entry protocol in Secure Simple Pairing in
the Bluetooth standard v5.2. In this thesis, we propose a simple enhancement for
the passkey entry protocol in the authentication stage 1 of Secure Simple Pairing
(SSP) using preexisting cryptographic hash functions and random integer gener-
ation present in the protocol. Our research mainly focuses on strengthening the
passkey entry protocol and protecting the devices against passive eavesdropping and
active Man-in-the-middle (MITM) attacks in both Bluetooth Basic Rate/Enhanced
Data Rate (BR/EDR) and Bluetooth Low Energy (BLE). In addition to increasing
the security of the protocol, our proposed model will also signi cantly reduce the
computation cost and the communication cost of the protocol. This model can be
implemented for any Bluetooth device which uses the passkey entry protocol and
is of version 4.2 or greater. | en_US |
