Whenever we are deploying data in public cloud, we are doing with semi-reliable cloud servers present outside the data owner's reliable domain. To avoid hazardous service providers trying to access delicate data from data owners we are encrypting that data. In this situation conducting the authentication approach over the data becomes a very tough task. So, by using Attribute -Based encryption we can provide access policies among the attributes which can proved flexibility, secured access controls over the deployed data. But we have a problem with ABE that it does not support the access control mechanisms by combination. Here in this proposed paper, we are applying a scheme where different users who are having different attribute sets can approach the data using collaboration provided if the data owner accepts the combination with that access policy. If the combination is not designed in access policy, then it is considered as conspiracy and request is denied. So, we introduce attribute-based combined authentication strategy through assigning translation nodes in the access format.
