Disclosed herein is an apparatus for detecting infrasound. The apparatus for detecting infrasound includes a sound wave detector including a diaphragm dividing an inner space of a first container into a first space and a second space, and a microchannel assembly including a second container having an inner space with one of the spaces divided by the diaphragm and a plurality of microchannels having different resistance values with respect to transmission of a sound wave, and exposing the inner space of the second container to the air through one of the plurality of microchannels. Such an apparatus for detecting infrasound may have various cut-off frequencies according to the number of the microchannels.

The present invention provides a method of validating a certificate by a certificate validation server using certificate policy and certificate policy mapping in a public key infrastructure (PKI). If the certificate validation server receives, from a client, an object certificate to be validated, a certificate of a certification authority which the client trusts, and a certificate policy which will be applied to validation of the object certificate, and receives a request for validation of the object certificate, the certificate validation server creates a certification path for the object certificate in response to the request. The certificate validation server validates the created certification path using a certificate policy mapping table if the validation of the object certificate is allowed, and then transmits a result message to the client according to the result of the validation of the certification path.
