Recently, based on the homomorphic signatures, the authentication schemes, such as homomorphic subspace signature (HSS) and key predistribution-based tag encoding (KEPTE), have been proposed to resist against pollution attacks in network coding. In this paper, we show that there exists an efficient multi-generation pollution attack on HSS and KEPTE. In particular, we show that using packets and their...
Autonomic networks are networks that are self- organized with decentralized control and management. Accurate trust establishment and maintenance is essential for secure and reliable message transmissions in autonomic networks. Because of the mobility and dynamics, trust management in autonomic networks is a much more dynamic problem than in traditional server-based networks. In traditional networks,...
