PROBLEM TO BE SOLVED: To provide a wireless communication apparatus capable of performing wireless communication while securing an irreducibly minimum security level depending on predetermined encryption in a communication group. SOLUTION: In a communication system, a first wireless communication apparatus belonging to a communication group receives a connection request frame including a notifying security level from a second communication apparatus outside 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 strength. In the first communication apparatus, the notifying security level is compared with a reference level, and a response frame describing connect rejection and connection permission is generated and transferred to the second communication apparatus, the connect rejection representing the rejection of connection to the second communication apparatus and the connection permission representing the permission of connection to the second communication apparatus.
