This paper proposes a secure protocol for creating spontaneous wireless ad hoc networks. It uses a hybrid symmetric/asymmetric scheme and trust between users to exchange initial data and secret keys for encrypting data. The protocol allows networks to self-configure and share secure services without infrastructure by distributing the certification authority and network management between trusted users. It applies asymmetric cryptography for device identification and symmetric cryptography to exchange session keys, providing authentication without anonymity. The paper details the network creation stages and protocol operation, and compares it to other ad hoc network protocols.
A secure protocol for spontaneous wireless ad hoc networks creation
- 1. A Secure Protocol for Spontaneous Wireless Ad Hoc Networks Creation ABSTRACT: This paper presents a secure protocol for spontaneous wireless ad hoc networks 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 compare the protocol with other spontaneous ad hoc network protocols in order to highlight its features and we provide a security analysis of the system.
- 2. EXISTING SYSTEM: The existing system objective is the integration of services and devices in the same environment, enabling the user to have instant service without any external infrastructure. Because these networks are implemented in devices such as laptops, PDAs or mobile phones, with limited capacities, they must use a lightweight protocol, and new methods to control, manage, and integrate them. Methods based on imitating the behavior of human relations facilitate secure integration of services in spontaneous networks. Furthermore, cooperation among the nodes and quality of service for all shared network services should be provided. DISADVANTAGES OF EXISTING SYSTEM: All nodes may not be able to execute routing and/or security protocols. Energy constraints, node variability, error rate, and bandwidth limitations mandate the design and use of adaptive routing and security mechanisms, for any type of devices and scenarios. Dynamic networks with flexible memberships, group signatures, and distributed signatures are difficult to manage. To achieve a reliable communication and node authorization in mobile ad hoc networks, key exchange mechanisms for node authorization and user authentication are needed security methods such as pre-distribution key

But these methods are not enough for spontaneous networks because they need an initial configuration or external authorities PROPOSED SYSTEM: The network and protocol proposed in this paper can establish a secure self- configured environment for data distribution and resources and services sharing among users. Security is established based on the service required by the users, by building a trust network to obtain a distributed certification authority. A user is able to join the network because he/she knows someone that belongs to it. Thus, the certification authority is distributed between the users that trust the new user. The network management is also distributed, which allows the network to have a distributed name service. We apply asymmetric cryptography, where each device has a public-private key pair for device identification and symmetric cryptography to exchange session keys between nodes. There are no anonymous users, because confidentiality and validity are based on user identification. ADVANTAGES OF PROPOSED SYSTEM: We presented the basis to setup a secure spontaneous network

To solve mentioned security issues, we used an authentication phase and a trust phase We presented a mechanism to allow nodes to check the authenticity of their IP addresses while not generating duplicated IP addresses. The mechanism helps nodes to authenticate by using their IP addresses. We have used this mechanism in the secure protocol presented in this paper, but it can be replaced by any other IP address assignment mechanism. ALGORITHMS USED: Algorithm1- Algorithm for joining a new node. Algorithm2- New network creation procedure. Algorithm 3-Algorithm when data packets are received.
