Bluetooth/セキュアコネクション
Bluetooth Classic/セキュアコネクション
- BR/EDR Secure Connections
概要
- Bluetooth 4.1 added the Secure Connections feature to the BR/EDR phyisical transport, which upgraded Secure Simple Pairing to utilize the P-256 elliptic curve, device authentication to use FIPS-approved algorithms (HMAC-SHA-256? and AES-CTR?).
- Secure Connections also added message integrity (AESCCM).
BLE/セキュアコネクション
概要
- Bluetooth 4.2 added the Secure Connections feature to the LE physical transport, which upgraded LE pairing to utilize FIPS-approved algorithms (AES-CMAC and P-256 elliptic curve) and adapts the Numeric Comparison association model to be used on the Bluetooth LE physical transport.
- It also includes provisions for a key generated using Secure Connections on either physical transport to preclude the need for the user to pair a second time on the other physical transport.
