VANET (vehicle Network) is emergent technologies that they deserve, recently, the attention of the industry and the academics institution .VANET is having many applications include safety applications, traffic efficiency enhancements, and infotainment service. vehicular network face more challenging task due to high speed and city environment characteristics. In this paper before using three protocols namely a geo-cast protocol ,baseline protocol And an aggregation protocol. a baseline represent the connectivity of node based on the chosen simulation, Advanced Adaptive Geo-cast (AAG) ,this protocol represent for Geo-cast protocol. An aggregation uses fixed road size segment ,its atomic observation are average. In this paper to increase the security for a vehicular communication introduce cryptography technique using one way hash shine algorithm
