主权项 1. A communication apparatus comprising: a receiver configured to receive a plurality of communication parameter sets, which comprise a first communication parameter set including information on a first encryption key to encrypt communication with another communication apparatus and a second communication parameter set including information on a second encryption key to encrypt communication with said another communication apparatus, the first communication parameter set being different from the second communication parameter set, from said another communication apparatus; a requestor configured to request said another communication apparatus to establish first direct connection using the first communication parameter set for encrypted communication with said another communication apparatus using the first encryption key, and to request said another communication apparatus to establish second direct connection using the second communication parameter set for encrypted communication with said another communication apparatus using the second encryption key, wherein, the requestor requests said another communication apparatus to establish the second direct connection in response to failure to establish the first direct connection according to a request to establish the first direct connection and re-requests said another communication apparatus to establish the first direct connection in response to success in establishing the second direct connection, wherein the requestor re-requests said another communication apparatus to establish the second direct connection using the second communication parameter set for encrypted communication with said another communication apparatus using the second encryption key in response to failure to establish the first direct connection according to a re-request to establish the first direct connection; and at least one processor configured to control at least one of the receiver, and the requestor.
