Abstract

A communication unit and a controller are included, the communication unit being configured to communicate with a communication apparatus using a first communication procedure in which authentication of the communication apparatus is performed in order to retain a communication session with the communication apparatus and using a second communication procedure that does not require authentication of the communication apparatus in order to communicate with the communication apparatus, the controller being configured to perform, using the first communication procedure and the second communication procedure, control under which it is determined whether a communication session with the communication apparatus is to be retained and perform control under which a limit is put on retaining of the communication session with the communication apparatus through the second communication procedure in a case where the communication apparatus is not authenticated as a certain communication apparatus through the first communication procedure.

Claims12

Dependent claims

A communication apparatus which communicates with another communication apparatus based on both of a first communication protocol which supports an authentication function and a second communication protocol which does not support the authentication function, the communication apparatus comprising:

an authentication unit configured to perform first authentication processing according to the first communication protocol in order to establish a communication session with said another communication apparatus, and to perform second authentication processing according to the first communication protocol after the establishment of the communication session with said another communication apparatus in order to authenticate said another communication apparatus;
a communication unit configured to communicate with said another communication apparatus based on the first communication protocol using the communication session established based on the first authentication processing and to communicate with said another communication apparatus based on the second communication protocol different from the first communication protocol, wherein the communication based on the first communication protocol and the communication based on the second communication protocol are performed by the communication unit in parallel;
a first determination unit configured to determine whether the second authentication processing according to the first communication protocol and performed after the establishment of the communication session with said another communication apparatus in order to authenticate said another communication apparatus is succeeded;
a second determination unit configured to determine, after the establishment of the communication session with said another communication apparatus, whether the communication unit receives from said another communication apparatus data according to the second communication protocol at a timing according to a predetermined time interval;
and
a controller configured to, according to both of a determination result by the first determination unit performed after the establishment of the communication session with said another communication apparatus and a determination result by the second determination unit performed after the establishment of the communication session with said another communication apparatus, terminate the communication session established based on the first authentication processing according to the first communication protocol with said another communication apparatus.

3 more elements

A communication method, implemented at a communication apparatus which communicates with another communication apparatus based on both of a first communication protocol which supports an authentication function and a second communication protocol which does not support the authentication function, the communication method comprising:

performing first authentication processing according to the first communication protocol in order to establish a communication session with said another communication apparatus;
performing second authentication processing according to the first communication protocol after the establishment of the communication session with said another communication apparatus in order to authenticate said another communication apparatus;
communicating with said another communication apparatus based on the first communication protocol using the communication session established based on the first authentication processing and communicating with said another communication apparatus based on the second communication protocol different from the first communication protocol, wherein the communication based on the first communication protocol and the communication based on the second communication protocol are performed in parallel;
a first determination step of determining whether the second authentication processing according to the first communication protocol and performed after the establishment of the communication session with said another communication apparatus in order to authenticate said another communication apparatus is succeeded;
a second determination step of, after the establishment of the communication session with said another communication apparatus, determining whether the communication apparatus receives from said another communication apparatus data according to the second communication protocol at a timing according to a predetermined time interval;
and
terminating the communication session established based on the first authentication processing according to the first communication protocol with said another communication apparatus according to both of a determination result by the first determination step performed after the establishment of the communication session with said another communication apparatus and a determination result by the second determination step performed after the establishment of the communication session with said another communication apparatus.

A recording medium storing a program comprising instructions, which when executed by a computer of a communication apparatus which communicates with another communication apparatus based on both of a first communication protocol which supports an authentication function and a second communication protocol which does not support the authentication function, cause the computer to perform a method comprising:

performing first authentication processing according to the first communication protocol in order to establish a communication session with said another communication apparatus;
performing second authentication processing according to the first communication protocol after the establishment of the communication session with said another communication apparatus in order to authenticate said another communication apparatus;
communicating with said another communication apparatus based on the first communication protocol using the communication session established based on the first authentication processing and communicating with said another communication apparatus based on the second communication protocol different from the first communication protocol, wherein the communication based on the first communication protocol and the communication based on the second communication protocol are performed in parallel;
a first determination step of determining whether the second authentication processing according to the first communication protocol and performed after the establishment of the communication session with said another communication apparatus in order to authenticate said another communication apparatus is succeeded;
a second determination step of, after the establishment of the communication session with said another communication apparatus, determining whether the communication apparatus receives from said another communication apparatus data according to the second communication protocol at a timing according to a predetermined time interval;
and
terminating the communication session established based on the first authentication processing according to the first communication protocol with said another communication apparatus according to both of a determination result by the first determination step performed after the establishment of the communication session with said another communication apparatus and a determination result by the second determination step performed after the establishment of the communication session with said another communication apparatus.
