COMMUNICATION DEVICE AND COMMUNICATION METHOD
First Claim
1. A communication device configured to perform a communication by employing first and second communication units, comprising:
- an interface configured to receive communication data including at least a random number generated for every connection with another communication device, and authentication method information indicating an authentication method at the second communication unit, from the another communication device through the first communication unit; and
a hardware processing unit configured to determine, based on the authentication method information included in the communication data, whether or not the another communication device accepts a public key system, wherein,when the processing unit has determined that the another communication device does not accept the public key system, the random number is set as a temporal key and authentication with the another communication device is done using the temporal key, through the second communication unit.

Abstract
A communication device for performing communication by employing first and second communication units, includes: a reception unit for receiving a communication packet including a random number generated for every connection with another communication device, a certificate calculated with the random number, and authentication method information indicating whether or not an authentication method at the second communication unit is compatible with the public key system, through the first communication unit; and a method determining unit for determining whether or not an originator of the communication packet accepts public key encryption based on the authentication method information included in the communication packet; wherein in a case of the method determining unit determining that the originator of the communication packet does not accept the public key system, the random number included in the communication packet is replied to the originator as the identification information of the device itself.

9. A communication method by a communication device configured to perform a communication by employing first and second communication units, comprising:
-
receiving communication data including at least a random number generated for a connection with another communication device, and authentication method information indicating an authentication method at the second communication unit, from the another communication device through the first communication unit; determining, based on the authentication method information included in the communication data, whether or not the another communication device accepts a public key system; and when the determining determines that the another communication device does not accept the public key system, the random number is set as a temporal key and authentication with the another communication device is done using the temporal key, through the second communication unit.

10. A communication device configured to perform a communication by employing first and second communication means, comprising:
-
means for receiving communication data including at least a random number generated for a connection with another communication device, and authentication method information indicating an authentication method at the second communication means, from the another communication device through the first communication means; and determination means for determining, based on the authentication method information included in the communication data, whether or not the another communication device accepts a public key system, wherein, when the determination means has determined that the another communication device does not accept the public key system, the random number is set as a temporal key and authentication with the another communication device is done using the temporal key, through the second communication means.
