Dynamic Key for Secure Communication among the Flexible Nodes

Vijay Kumar Mahto | D. Praveen Kumar

Abstract: This project presents a dynamic key for secure communication among the flexible node which uses a hybrid symmetric /asymmetric scheme and the trust between users in order to exchange the initial data and to exchange the secret keys that will be used to encrypt the data. Trust is based on the first visual contact between users. Our proposal is a complete self-configured secure protocol that is able to create the network and share secure services without any infrastructure. The network allows sharing resources and offering new services among users in a secure environment. The protocol includes all functions needed to operate without any external support. We have designed and developed it in devices with limited resources. Network creation stages are detailed and the communication, protocol messages, and network management are explained. Our proposal has been implemented in order to test the protocol procedure and performance. Finally, we provide a security analysis of the system.
