Method for accessing a user operable device of controlled access
First Claim
1. A method, comprising:
- transmitting an inquiry from a mobile device of a user via a wide area transmission network to a key authority for obtaining an access key for accessing functions of a user operable device having limited accessibility;
receiving a request for information from the key authority;
transmitting the requested information to the key authority, wherein the information is used by the key authority for co-coding the access key with one or more conditions for operating the user operable device;
receiving the access key assigned by the key authority via the wide area transmission network;
storing the access key; and
transmitting the access key to a controller unit of the user operable device via a short range communication network for accessing the functions of the user operable device;
wherein a validation key is generated by the controller unit for comparing with the access key, and if the access key is validated, the access to the functions of the user operable device is granted according to the conditions co-coded in the access key.
