The Public Key Infrastructure(PKI) can provide various security services in e-commerce.When combine of different companies happens,the multiple PKIs deployed by different companies should be merged.In this paper,first the common merging ways are analyzed.Then considering the specialties of these merging problems, an efficient way based on hierarchy structure is proposed.The new scheme makes a small change of those existing PKIs and issues a few certificates.The reconstruction process is quick and low cost.After merging,the new PKI can not only make an efficient path construction and validation but also fit for the enterprise management.In addition,some conceptions used in PKI have also been formalized in order to describe the scheme clearly.
