This paper analyses the PKI theory architecture detailedly, combining with researching the information security status quo and the wireless communication systems. On this condition, we put forward the feasible WPKI system, CA sub-system and RA sub-system logical frame diagram and network structure blue print. The technical criterions in the system and core content of WPKI, includes the certificate management(certificate requirement, certificate issue, certificate revocation, certificate query and so on), are discussed at length. In the end, the systems function and performance are tested.
