KDSR

This article deals with a key distribution protocol to secure routing in large-scale Wireless Sensor Networks (WSNs) and proposes a new protocol called KDSR. The authors' protocol has two originalities: to provide a secure network structure for large-scale WSNs, and to use lightweight local process to share efficiently the Local Broadcast Keys, the Pairwise Keys and the Global Broadcast Key. These keys are useful to secure several communication patterns in WSNs: one-to-many, one-to-one and one-to-all. Security analyses show that KDSR can withstand several attacks against WSNs. Through fast node revocation process, KDSR offers a good resilience against node capture. Immunity against MiM and replay attacks are well checked with the AVISPA tools. The experimentations are done on real TelosB motes and through the TOSSIM simulator. Simulation results confirm that KDSR is scalable, provides a good key connectivity and a good resilience. Comparison to earlier work shows that KDSR causes less computation complexity, less communication overhead and much less storage space even for large-scale WSNs.

Global Workspace Theory and Animal Consciousness

Peter Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in nonhuman animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. Second, it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is (determinately) shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human.

The development of Complex Emergent Modularity: A reply to Favela, Amon, & van Rooij (2018)

In our reply to Favela, Amon, & van Rooij (2018) we note points of agreement such as the necessity for the interaction between components in a system for it to be complex emergent and that the Dual Processes approach to human thinking has limitations. We also discuss several critical points of disagreement with the paper. We assert that Complex Emergent Modularity (CEM) does not proliferate the interaction problem but instead proposes a solution to the problem based on the contribution of the global workspace and the process of global broadcast. The nature of the entities which interact is described and emphasized as central to CEM theory.

China's diplomatic investment may not yield returns

Subject China's diplomatic capabilities. Significance China under President Xi Jinping has become more assertive, more activist and more multilateral in its foreign policy. Initiatives such as the 'one belt and one road' commercial strategy, rapid expansion of China's global broadcast media and development of bilateral ties by state-owned enterprises all suggest that China's global network has stronger and deeper roots than before. Beijing's expanding role in multilateral fora, especially new China-led organisations such as the New Development Bank, make a clear break with Deng Xiaoping's strategy of inconspicuous passivity. Impacts Cultivation of effective diplomatic channels will pay off most in managing relations with antagonists, or where interests diverge. No other country shares China's values sufficiently to upgrade a convergence of interests into a firm alliance. The weakness of China's foreign ministry within the bureaucracy gives Chinese diplomats less influence than their foreign counterparts.
