Wireless communication device, portable terminal, communication control program and communication system
First Claim
1. A wireless communication device, comprising:
- a wireless communication unit which communicates with other communication device located at a prescribed range;
a first identification information generator which generates first identification information including a service name of available service and inherent information;
an encryption unit configured to encrypt said first identification information by using a prescribed encryption key to generate encryption data;
a second identification information generator which generates second identification information including the service name, the inherent information and the encryption data; and
an inherent information transmitter which transmits the second identification information for an other communication device which has requested transmission of the inherent information.

18. A computer readable recording medium storing a computer program code which controls a portable terminal, to perform controls comprising:
-
communicating with other communication devices located at a prescribed range;
searching a communication device capable of communicating;acquiring first identification information transmitted from the searched communication device; extracting a service name, inherent information and encryption data from the acquired first identification information; decrypting the encryption data by using a prescribed decryption key;
comparing the decoded data with the extracted service name and inherent information, and determining whether or not the communication device searched by the searching unit is reliable based on the comparison result;and inhibiting communication with the communication device determined to be unreliable by the comparison result.
