For BLE: a persistent key that is stored in both devices and used to derive a fresh encryption key each time the devices use encryption.
Host Controller Interface [HCI]
An interface that enables a controller to communicate with a driver.
Enhanced Data Rate [EDR]
“One of the signaling modes introduced in version 2.0 of the Bluetooth protocol, supporting 3 Mbit/s signaling rate.”
Encrypted Diversifier [EDIV]
“(Bluetooth) A value used along with a random number during the process of creating and identifying a long-term key.”
Direct Test Mode [DTM]
A mode used for RF testing used while manufacturing and for certifying BLE devices.
Connection Signature Resolving Key [CRSK]
“In Bluetooth, CRSK is a security key used to sign transmitted data and to verify signatures on received data.”
