Effectively Secure Data Retrieving for Using Three Different Level Security

Abstract

The efficient message authentication is one of the most effective ways to thwart unauthorized and corrupted messages from being forwarded in wireless sensor networks. For this reason, many message authentication schemes have been developed, based on either symmetric key cryptosystems or parallel cryptosystems. Most of them, however, have the limitations of high complex and communication overhead in addition to lack of scalability and resilience to node compromise attacks. To solve these issues, a polynomial-based scheme was recently introduced. However, this scheme and its extensions all have the weakness of a built-in threshold determined by the degree of the polynomial based scheme: when the number of messages transmitted is larger than this threshold, the adversary can fully recover the polynomial. In this paper, we propose a scalable authentication scheme based on elliptic curve cryptography. While enabling intermediate nodes authentication, our proposed scheme allows any node to transmit an unlimited number of messages without suffering the threshold problem. In addition, our scheme can also provide message source privacy.
