Recent applications of Case-Based Reasoning (CBR) industry have highlighted two major difficulties with developing CBR systems. These are, the integration of types of knowledge which are orthogonal to the knowledge represented by cases and the case engineering bottleneck. Exploiting the affinity between Data Mining and CBR we propose a unifying framework(More)
Signcryption is a cryptographic primitive which offers authentication and confidentiality simultaneously with a cost lower than signing and encrypting the message independently. Ring signcryption enables a user to anonymously signcrypt a message on behalf of a set of users including himself. Thus a ring signcrypted message has anonymity in addition to(More)

In a multi-hop wireless network (MWN), a source node relays its packet through one or more intermediate nodes to the destination. When an intermediate node relays others packets, its energy and processing power are consumed. So some nodes do not forward other node's packets. But at the same time, they relay their own packets through other nodes. Such nodes(More)
