Nowadays, clud computing or clud networks compulation systems take into account as one of the most important networks. This network presents signification service to its users. Since the users have many individual information in these networks, therefore being secure is so important to for this respect, these networks must be secured by using the system of proof of identity and powerful cryptography systems.This paper presented a new model for proving identity of users in the clud computing networks.In this paper, all the stage of the operation of the users proof of identity accomplished by the kerbros algoritm. Also the operation of cryptography can be done by using the kerbros algoritm.
