Privacy-preserving secure device and accessory connection and communication for first party and third-party applications

A computing device, comprising:

• one or more memories;
• and
• one or more processors in communication with the one or more memories and configured to execute instructions stored in the one or more memories to perform operations comprising:
• detecting, by a system process of the computing device, a trigger for establishing a communication pathway with an accessory device from an application that is associated with the accessory device, the trigger including an accessory identifier;
• identifying, by the system process of the computing device, a set of cryptographic information that corresponds to the accessory device based on a mapping of accessory identifiers to sets of cryptographic information;
• accessing, by the system process of the computing device, an advertising message that corresponds to the set of cryptographic information;
• establishing, by the system process of the computing device, the communication pathway between the mobile device and the accessory device using information that is associated with the advertising message;
• and
• permitting, by the system process of the computing device, communication between the application and the accessory device via the communication pathway.

A non-transitory computer-readable medium storing a plurality of instructions that, when executed by one or more processors of a computing device, cause the one or more processors to perform operations comprising:

• detecting, by a system process of the computing device, a trigger for establishing a communication pathway with an accessory device from an application that is associated with the accessory device, the trigger including an accessory identifier;
• identifying, by the system process of the computing device, a set of cryptographic information that corresponds to the accessory device based on a mapping of accessory identifiers to sets of cryptographic information;
• accessing, by the system process of the computing device, an advertising message that corresponds to the set of cryptographic information;
• establishing, by the system process of the computing device, the communication pathway between the mobile device and the accessory device using information that is associated with the advertising message;
• and
• permitting, by the system process of the computing device, communication between the application and the accessory device via the communication pathway.
