The Apple Magic Keyboard incorporates security measures, especially the models with Touch ID.
Security Features of Apple Magic Keyboard with Touch ID
The Magic Keyboard with Touch ID employs encryption to protect sensitive information transmitted between the keyboard and the paired Mac. Here’s a breakdown:
-
Encryption: After secure pairing, all Touch ID data communicated between the Mac and the Magic Keyboard with Touch ID is encrypted by AES-GCM with a key length of 256 bits, and with ephemeral ECDH keys using NIST P-256 curve based on the stored identities. (13-May-2022)
- AES-GCM (Advanced Encryption Standard - Galois/Counter Mode): A widely used and robust encryption algorithm that provides both confidentiality and authentication. The 256-bit key length indicates a high level of security, making it extremely difficult to crack.
- Ephemeral ECDH keys using NIST P-256 curve: Ephemeral keys are temporary cryptographic keys that are created for each session and then discarded. ECDH (Elliptic-Curve Diffie-Hellman) is a key exchange protocol that enables two parties to establish a shared secret over an insecure channel. NIST P-256 is a specific elliptic curve recommended by the National Institute of Standards and Technology (NIST). Using this method enhances the security of the key exchange process.
- Secure Pairing: The keyboard and Mac establish a secure, trusted connection during the initial pairing process. This prevents unauthorized access to the communication channel.
-
Touch ID Security: The Touch ID feature itself provides an additional layer of security by requiring biometric authentication for certain actions, such as unlocking your Mac or making purchases.
Overall Security Assessment
Considering the encryption methods employed, the Apple Magic Keyboard with Touch ID appears to be designed with strong security measures in place to protect sensitive information during transmission.
