In today’s world, lots of transactions are carried out online via various applications using computer networks. Such sensitive information must be protected against any vulnerability. On the other hand, networks are becoming infrastructure less, dynamic in topology, nodes are mobile and with limited resources, communication links are not secured and mostly wireless. This has made security a very difficult task and concentrated efforts are required to design a specialized security solution. In this paper, we have presented a secure identity based scheme consisting of novel and highly secure key generation using identity of user. Two levels of security have been provided in the presented scheme using both, RSA algorithm and Elliptic curve cryptography. Node’s master private and public keys are generated using RSA algorithm. Fingerprint of user has been deployed as identity and hence used for identification key generation. Elliptic curve is defined using both, node’s master private key and identification key. Performance is measured using time analysis to accomplish various operations in the proposed scheme.Keywords: Identity based security, key management, key generation, key revocation, finger print
