Abstract

A method of transferring data and a method of transferring contents are provided. In the method of transferring data in a data interoperable environment, a secure authenticated channel is established with a receiving entity corresponding to receiver information included in a received control message, when the control message is received from a control entity, a plurality of data designated by the control entity are transmitted to the receiving entity through the established secure authenticated channel, and an event message for representing a transmission status of the transmitted data is transmitted to the control entity. Accordingly, it is possible to transmit the plurality of data through a single transmission session and provide a transmission status of each data through an event.

Claims

1. A computer-implemented method comprising:

transmitting a request to a designated control entity to access a domain;

transmitting to devices associated with the domain, data describing a device characteristic;

causing one of the devices to be designated as the control entity for the domain based on transmitting the data;

establishing a secure authenticated channel with a device; and

transmitting content or license to the device using the established secure authenticated channel.

2. The method of claim 1, wherein causing the one of the devices to be designated as the control entity for the domain based on transmitting the data further comprises:

launching a control entity electing procedure that elects the control entity based on comparing, among the devices, a capability of each device with each other.

3. A device comprising:

an interface configured to;

transmit a request to a designated control entity to access a domain,

transmit to devices associated with the domain, data describing a device characteristic,

establish a secure authenticated channel with a device, and

transmit content or license to one of the devices using the established secure authenticated channel; and

a processor configured to cause the one of the devices to be designated as the control entity for the domain based on transmitting the data.

4. The device of claim 3, wherein causing the one of the devices to be designated as the control entity for the domain based on transmitting the data further comprises:

launching a control entity electing procedure that elects the control entity based on comparing, among the devices, a capability of each device with each other.

5. A system comprising:

one or more computers;

a computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, causes the one or more computers to perform operations comprising;

transmitting a request to a designated control entity to access a domain,

transmitting to devices associated with the domain, data describing a device characteristic,

causing one of the devices to be designated as the control entity for the domain based on transmitting the data,

establishing a secure authenticated channel with a device, and

transmitting content or license to the device using the established secure authenticated channel.

6. The system of claim 5, wherein causing the one of the devices to be designated as the control entity for the domain based on transmitting the data further comprises:

launching a control entity electing procedure that elects the control entity based on comparing, among the devices, a capability of each device with each other.
