A secured trust creation in VANET environment using random password generator

A VANET is a adhoc network that uses moving cars as nodes in a network to create a mobile network. VANET allows cars approximately 100 to 300 metres of each other to connect and in turn create a network with a wide range. As cars falls out of the signal range and goes out of the network and other cars follows the same network and now mobile network is created. Here the communication between the nodes takes place in a secured way by using security algorithms like TESLA and ECDSA. VANET uses a hardware called TPM (Trusted platform module) to provide a secured communication between the nodes. For a secured communication between the nodes, a node must trust the communicating node before communication with it and if it is found legal then communicate with it. While trusting, if that node is found to be malicious one, avoid communication with it. In our proposed work, instead of maintaining long records of node details in central trusted authority, using password generator generate a password and parent node will distribute them to the child nodes.
