PHONE AS A KEY LOW LATENCY VEHICLE ACCESS

The invention provides a phone as a key low latency vehicle access. A Phone-as-a-Key (PaaK) system includes a pre-processor, a secure processor disposed in communication with the pre-processor, a cache memory associated with the pre-processor and the secure processor, and a memory for storing executable instructions. The pre-processor and the secured processor are configured to perform steps that can mitigate delay caused by mobile device authentication. For example, the pre-processor authenticates an authentication message associated with a mobile device used as a key for the vehicle, and stores the message in the cache memory. The pre-processor receives a door latch actuation signal, and initializes the secure processor in response. The pre-processor then provides access to the vehicle based on the secure processor initialization instruction, and the authentication message stored in the cache memory. 本公开提供了"手机即钥匙的低延时车辆访问"。一种手机即钥匙(PaaK)系统，包括：预处理器；安全处理器，所述安全处理器被设置成与所述预处理器通信；高速缓冲存储器，所述高速缓冲存储器与所述预处理器和安全处理器相关联；以
