Payment through mobile in a disaster field gives the advantage to provide electronic transactions for people buying recovery items like foodstuffs garments and medicine. Existing system uses a new mobile payment method which makes use of infrastructure less mobile adhoc networks to permit transactions that permit customers to buy in disaster areas. However few issues arise in this system while payment is in process. In this paper proposed a method for secured transaction between a vendor and a customer using offline MANET concept. The customer and the vendor should register with the bank and gets authenticated separately. The protocol used in the proposed system works on two phases. (i) Pairing phase & (ii) Payment phase. At the completion of pairing phase the vendor and the customer should share their public keys. This is done to improve message integrity & authenticity., International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2019, CSEIT195317
