Bluetooth Simple Pairing Whitepaper

An overview of the cryptographic procedures and algorithms for the Simple Pairing feature in the forthcoming Lisbon release of the Bluetooth Core Specification.

Introduction

This whitepaper details the cryptographic functions, protocols, and algorithms that constitute the Simple Pairing feature within the Bluetooth Core Specification's Lisbon release. It is intended for the security community to facilitate a peer review process prior to the official adoption of the Lisbon release.

The primary objective of Simple Pairing is to enhance the user experience by simplifying the device pairing process. Concurrently, it aims to maintain and improve the overall security of Bluetooth wireless technology. This document delves into the technical aspects, including various association models and security protocols, designed to achieve these goals.

Key Features and Goals

  • Enhanced security against passive eavesdropping and man-in-the-middle attacks.
  • Simplification of the pairing process for end-users.
  • Exceeding the security levels of previous Bluetooth specifications.
  • Detailed explanation of association models: Numeric Comparison, Just Works, Out Of Band, and Passkey Entry.
  • In-depth look at the security protocol phases, including public key exchange, authentication stages, and link key calculation.
