3.1

associated

successful negotiation of a bi-directional wireless link with a coordinator

Note 1 to entry: Associated networks require communication be maintained and monitored for a period of time.

3.2

association

service used to establish membership for a device communicating within the wireless network described in this document

3.3

authentication

ATH

process of determining whether an entity or data is/are who or what, respectively, it claims to be

Note 1 to entry: The types of entity authentication referred to in this document are Tag authentication, Interrogator authentication, and Tag-Interrogator mutual authentication. For data authentication, see authenticated communications (3.4) .

3.4

authenticated communications

communications in which message integrity is protected

3.5

block cipher

cryptographic function that operates on strings of fixed size

3.6

chip

smallest unit of signal after spectrum spreading

Note 1 to entry: In the spreading process, an information bit is usually represented by a number of coded signals, wherein a coded signal is called a chip.

3.7

coordinator

full-function device (FFD) capable of relaying messages

Note 1 to entry: If a coordinator is the principal controller of a personal area network (PAN), it is called the PAN coordinator.

3.8

data server

device data termination point

3.9

device

any entity that meets the ISO/IEC/IEEE 8802-15-4 medium access control (MAC), physical interface to the wireless medium, and this document

Note 1 to entry: A device may be a reduced-function device (RFD) or a full-function device (FFD).

3.10

encryption

transformation of a message into a new representation so that privileged information is required to recover the original representation

3.11

full-function device

FFD

device capable of operating as a coordinator

3.12

group key

key that is known only to a set of devices

3.13

hailing channel

ISO/IEC/IEEE 8802-15-4 radio channel used to broadcast the NDB

3.14

key

privileged information that may be used, for example, to protect information from disclosure to, and/or undetectable modification by, parties that do not have access to this privileged information

3.15

keyID

numerical designator for a single key

3.16

link key

secret key that is shared between precisely two devices

3.17

mesh networking

type of network where an FFD serves as a relay for other devices

3.18

message authentication code

MAC1

code, computed over bits in a message, that an Interrogator or a Tag may use to verify the integrity of the message

3.19

message integrity code

MIC

data whereby an entity receiving a message corroborates evidence about the true source of the information in the message and, thereby, evidence that the message has not been modified in transit

3.20

network channel

primary ISO/IEC/IEEE 8802-15-4 radio channel between a coordinator and remote devices

3.21

packet

formatted, aggregated bits that are transmitted together in time across the physical medium

3.22

password

information that is used to verify identities in the tag access (3.29) process

3.23

payload data

contents of a data message that is being transmitted

3.24

reduced-function device

RFD

device that is not capable of operating as a coordinator

3.25

secure communications

communications in which message confidentiality is protected

3.26

security

degree of protection against threats identified in a security policy

Note 1 to entry: A system is secure if it is protected to the degree specified in the security policy.

3.27

server connected coordinator

SCC

network coordinator that terminates the wireless protocol described in this document and is connected to control servers

3.28

tag

any device type associated with the device and capable of joining the network

3.29

tag access

process in which tags establish communication links with interrogators according to certain communication protocols
