Rational requirements have a special status in the theory of rationality. This is obvious in one sense: they supply the content of that theory. But I want to suggest that rational requirements have another special status—as objects of the theory of rationality. In slogan form, my thesis is: Fixed Point Thesis: Mistakes about the requirements of rationality are mistakes of rationality. The key c...

Farbod Akhlaghi has argued that noncognitivists and naturalists cannot explain the epistemic possibility of wholesale moral error. He thinks this shows noncognitivism naturalism are false. I argue have no trouble explaining error requirement to is plausible only on one particular conception possibility.

The research community has proposed numerous network security solutions, each dealing with a specific problem such as address spoofing, denial-of-service attacks, denial-of-quality attacks, reflection attacks, viruses, orworms.However, due to the lack of fundamental support from the Internet, individual solutions often share little common ground in their design, which causes a practical problem...

today advertisement is an important part of all businesses. using false information in these advertisements are always targeting consumers and rival traders. no doubt in these circumstances consumers need to be protected, however, it is not clear what kind of support and protection can be afforded for consumers and how they can be compensated? can they terminate the contract, or they have to ke...

Feature Selection in large multi-dimensional data sets is becoming increasingly important for several real world applications. One such application, used by network administrators, is Network Intrusion Detection. The major problem with anomaly based intrusion detection systems is high number of false positives. Motivated by such a requirement, we propose sv(M)kmeans: a two step hybrid feature s...

The false data injection attack is a major security threat in Wireless Sensor Network (WSN) since is degrades the network capability. The bandwidth efficient cooperative authentication (BECAN) scheme is used for filtering the false data injection attack. It is used to save energy of sensor nodes in WSN by early detection and filtering of maximum possible injected false data. Source authenticati...

False data injection attack and PDoS (path-based Denial of Service) attack are serious threats in wireless sensor networks. Existing schemes can effectively resist false data injection and PDoS attacks, but most of them can not find out the compromised node when the base station or sink node detect the report is invalid. In this paper, we propose a false data injection-resilient security routin...
