A new feature called CarKey was discovered in iOS 13.4. It basically turns an iPhone or Apple Watch into a car key. But a new patent shows that the function can control more than just cars.<\/strong><\/p>\n\n\n\n

The iOS 13.4 code contains an API that references "CarKey." It allows unlocking, locking, and starting a car using an iPhone or Apple Watch. A virtual key is generated as an NFC tag and stored in the Wallet app. But the feature apparently can do much more than just grant secure access to a compatible car. A new Apple patent describes a technology based on "CarKey" that allows secure access to much more. It can be used to control payments, doors, and entire systems. The patent description states:<\/p>\n\n\n\n

Techniques related to electronic security are disclosed, e.g., for authenticating a mobile electronic device to enable access to system functionality (e.g., physical access to the system, starting an engine\/motor, etc.). In some embodiments, a system and a mobile device exchange public keys from public key pairs during a pairing process. In some embodiments, an asymmetric transaction process includes generating a shared secret using a key derivation function over a key created using a secure key exchange (e.g., elliptic curve Diffie-Hellman) and verifying a signature of the system prior to transmitting information identifying the mobile device. In various embodiments, the disclosed techniques may increase transaction security and protection of identification information.<\/p><\/blockquote>\n\n\n\n

Works like Apple Pay<\/h3>\n\n\n\n\n\n\n\n

<\/p>\n\n\n\n

Basically, "CarKey" works like Apple Pay, but the feature has significantly more possible uses. Later in the patent, Apple describes various options for using "CarKey". For example, it can authorize systems, payment transactions and other electronic elements to perform a task. This also includes access to physical locations. We usually warn against patents because not every technology ends up actually being implemented. But in this case, Apple already seems to be getting serious, as iOS 13.4 shows - more on that below. (Photo by blackboard \/ Bigstockphoto)<\/em><\/p>\n\n\n\n
