Recently, Abadi .?[1] and Dwork .?[2] addressed this limitation by showing that memory access times vary much less than CPU speeds, and hence offer a viable alternative. In this paper, we further investigate the applicability of memory bound puzzles

However, the lack of structure can also be abused by malicious users. We explore one such attack, that enables malicious users to use unstructured P2P systems

Engineering Dynamic 3D Models of Lung protocol is more efficient than the recent protocol of Abdalla and Pointcheval (FC?2005), proven in the random oracle model. We also observe some limitations in the model due to Abdalla, Fouque and Pointcheval (PKC?2005) for proving security of such protocols.

In this paper, we show the new version is still insecure, and we find that the polynomial components of the cipher (..) satisfy nontrivial equations of the special form . which could be found with 2. computations. From these equations and consequently the lin
