PROBLEM TO BE SOLVED: To provide delivery and reception of keys between a server and one or more client terminals, in the field of content delivery system.SOLUTION: An electronic device receives from a mobile terminal (client device) 122 a request to transmit keys. In response to the request, a server 100 generates the keys and determines a best time to send the keys to the client device 122 such that a new connection is not required just for sending the requested keys. The best time to send the keys is during a scheduled connection for sending non-key data, which can be, for example a connection set up for transmitting system parameters, content data, etc. By sending the keys along with the non-key data, a need for a special connection is avoided. |
