Abstract: In a remote control method, a virtual private network is established between a home control network key and a home control network device of the remote control system in a property. In order to establish the virtual private network both the home control network key and device determine their network paths to the Internet from the data transfer network to which they are connected. The determined network paths are stored in a home control network server on the Internet. When it is desired to form a virtual private network, the home control network server supplies the stored network paths to the home control network key and the home control network device. By utilizing the received network paths the home control network key and the home control network device start establishing a virtual private network between them with several known by them establishing methods of a data transfer connection.

Abstract: In the method and system of establishing a trusted relationship, first a virtual private network is established between a key device and at least one locking device. Thereafter, in order to establish a trusted relationship the key device sends a message encrypted with its private cryptographic key to at least one locking device. The message comprises the certificate of the trusted key device and the certificate of some other device, with which the locking device that received the message shall establish a new trusted relationship. By using the established trusted relationship either a trusted relationship between the locking device and a new key device or a trusted relationship between two or more locking devices is established, whereby a virtual private network can be established between the locking devices.

Abstract: In a remote control method and remote control system, a virtual private network (55) is established between a home control network key (42b, 41c) and a home control network device (61). In order to create the virtual private network both the home control network key and the home control network device determine their network paths to the Internet (2) from the data transfer network (3, 5) to which they are connected. The determined network paths are stored in a home control network server (21) on the Internet (2). When it is desired to form a virtual private network, the home control network server (21) supplies the stored network paths to the home control network key (42b, 41c) and the home control network device (61).
