Communication system, wireless communication apparatus, and communication method
First Claim
1. A wireless communication apparatus which belongs to a wireless communication group, comprising:
- a receiver unit configured to receive an association request for data communication security from a wireless communication unit outside of the wireless communication group, the association request including information on a data security level used for communication data that is to be transmitted by the wireless communication unit;
a reference memory configured to store a reference security level assigned to the wireless communication group, the reference security level selected from a plurality of security levels corresponding to a plurality of encryption methods including at least one of non-encryption and a plurality of encryption strengths for communication data;
a control unit configured to compare the data security level with the reference security level to determine whether the data security level satisfies the reference security level of the group, and configured to generate a reply including information on either an association rejection or an association permission depending on a result of the comparison of the data security level with the reference security level; and
a transmitting unit configured to transmit the reply to the wireless communication unit,wherein the wireless communication unit transmits the communication data to the wireless communication apparatus after receiving the reply having an association permission, and after an authentication of the wireless communication unit has been performed.

Abstract
In a communication system, a first wireless communication apparatuses belonging to a communication group receives a connection request frame including a notifying security level from a second communication apparatus outside of the communication group. The first communication apparatus stores a reference security level peculiar to the communication group, which is selected from security levels depending on one of encryption methods including non-encryption and encryption strengths. In the first communication apparatus, the notifying security level is compared with the reference level, and a response frame including one of a connect rejection and a connection permission is described, is generated and transferred to the second communication apparatus. The connect rejection represents a rejection of connection to the second communication apparatus and the connection permission represents a permission of connection to the second communication apparatus.

20. A wireless communication method of determining a connection to a wireless communication unit with a reference security level assigned to a wireless communication group, the method comprising:
-
receiving an association request for data communication security from the wireless communication unit to the wireless communication group, the request including a data security level of data that is to be transmitted to a member of the wireless communication group by the wireless communication unit; storing a reference security level, the reference security level including a plurality of encryption methods selected from a plurality of security levels corresponding to at least one of non-encryption or a plurality of encryption strengths for communication data; generating a reply including an association rejection or an association permission, the association rejection and the association permission being determined by comparing the data security level with the reference security level, the association rejection representing a rejection of association to the communication unit and the association permission representing a permission association to the communication unit that is using the data security level; and transmitting the reply to the wireless communication unit, wherein the wireless communication unit transmits the communication data to a wireless communication apparatus of the wireless communication group after receiving the reply having an association permission, and after an authentication of the wireless communication unit has been performed.
