This document discusses Bluetooth security. It outlines Bluetooth's security framework, including link level security and service level security. At the link level, Bluetooth uses encryption, authentication, and authorization. It employs three security modes: non-secure mode; service level security; and link level security. Link level security initiates functions before channel establishment, while service level security initiates them after. The document also covers applications of Bluetooth, benefits, basic security definitions, and key management schemes. It concludes that while Bluetooth security was adequate for small networks initially, it may not be sufficient for larger or more sensitive transfers.

7. BASIC DEFINITION
 ENCRYPTION
 Transfers data to other form, can’t
understood without key.
 AUTHENTICATION
 The ensuring of the identity of another user.
 AUTHORIZATION
 Deciding, if a device is allowed to have access
to a service.

9. SECURITY LEVELS
 LINK LEVEL SECURITY
 The Bluetooth device initiates security
functions before the channel is established.
 SERVICE LEVEL SECURITY
 The Bluetooth device initiates security
functions after the channel is established
