BLE/セキュアコネクション
Top / BLE / セキュアコネクション

概要

  • 鍵生成のためECDH(Elliptic curve Diffie-Hellman:楕円曲線ディフィー・ヘルマン鍵共有)と呼ばれるアルゴリズムと、鍵交換用に新しいペアリング手順を使用する

メモ

  • Secure Connections on the LE physical transport upgrades LE Legacy Pairing to utilize FIPS-approved algorithms (AES-CMAC and P-256 elliptic curve) and adapts the Numeric Comparison association model of Secure Simple Pairing 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.
