In focus of achieving securing communication and protective users’ namelessness and site privacy in hybrid spontanepous networks. Symmetric-key-cryptography operations and payment system area unit wont to secure route discovery and information transmission. To cut back the overhead, the payment are often secured while not submitting or process payment proofs (receipts). To preserve users’ namelessness with low overhead, we have a tendency to develop economical name generation and trapdoor techniques that don't use the resource-consuming asymmetric-key cryptography. Pseudonyms don't need massive cargo deck or oft contacting a central unit for replenishment. Our trapdoor technique uses solely light-weight hashing operations. this can be vital as a result of trapdoors is also processed by an oversized range of nodes. Developing low-overhead secure and privacy-preserving protocol could be a real challenge due to the inherent contradictions: 1) securing the protocol needs every node to use one each identity, however a permanent identity mustn't be used for privacy preservation; and 2) the low overhead demand contradicts with the massive overhead usually required for protective privacy and securing the communication. Our analysis and simulation results demonstrate that our protocol will preserve privacy and secure the communication with low overhead.
