In existing symmetric searchable encryption scheme it aims to allow a user to outsource his/her encrypted data into a cloud server and delegate the latter to search on his/her behalf. In these schemes it does not qualify a new secure and scalable solution for the multiparty settings. The users outsource their encrypted data into cloud server and selectively authorize each data to search. Due to this possibility the cloud server may collude with some malicious user which is a challenge to have a secure and scalable multiparty searchable encryption scheme (MPSE).Now based on this analysis we will present a new secure model for MPSE by considering the best case and the worst case scenario. We use Data Encryption Standard (DSE) to implement MPSE.
