Then this paper introduces the basic theory and technology of PKI, introduces the related concepts of Multi-Tenancy including software as a service, Multi-Tenancy’s definition and the implementation techniques of Multi-Tenancy. After this, this paper does the study of identity authentication and data isolation method, proposes a distributed PKI suitable for the distributed environment of Multi-Tenancy services and an identity authentication scheme based on the PKI. Then, this paper analyses the identity authentication scheme, the process of certificate checking and the certificate holder’s checking.
