Abstract:
1. A method enabling cooperation between a SEND processing block and an IPSec processing block in an apparatus comprising a processor configured to execute an authentication cache management module, the method comprising: receiving an authentication completion report message including an IP address of a host whose authentication is completed by the SEND processing block; generating new authentication information corresponding to the same host and storing the new authentication information in a temporary storage area, when authentication information for the host is not present in the temporary storage area, wherein the authentication information includes the IP address of the host; and when an authentication check request message including an IP address is received from the IPSec processing block, checking, by referring to the temporary storage area, whether the IP address included in the authentication check request message is the same as the IP address of the host whose authentication was previously completed by the SEND processing block, and sending the result of checking to the IPSec processing block, wherein when the IP address included in the authentication check request message is present in the temporary storage area, authentication of the host corresponding to the IP address included in the authentication check request message is determined to be completed, and an authentication check pass message is sent to the IPSec processing block, and wherein both the SEND processing block and the IPSec processing block are executed by the processor.
