In the second contribution, entitled "Behavioral Characterization for Network Anomaly Detection," Victor P. Roche and Unai Arronategui propose a methodology for detecting abnormal traffic on the net, such as worm attacks, based on the obser- tion of the behavior of different elements at the network edges. This methodology means an advance in the detection of a new infection in the backbone of the network, but also in the identification of the infected hosts of a specific network. The authors try to detect network anomalies by tracking the behavior of different network levels. This proposed method is not based on intrinsic characteristics of the worm but on their manner of acting. This methodology has proved its effectiveness in real infections caused by viruses such as SpyBot and Agobot in accordance with experimental tests. In the third contribution, which is entitled "The Power of Anonymous Veto in Public Discussion," Feng Hao and Piotr Zielinski propose an exceptional solution--Anonymous Veto Network (or AV-net)--to allow a group of participants to compute a boolean-OR function securely. This protocol is provably secure under the Decision Diffie-Hellman (DDH) and random oracle assumptions.

The Transactions on Computational Science journal is part of the Springer series Lecture Notes in Computer Science, and is devoted to the gamut of computational science issues, from theoretical aspects to application-dependent studies and the va- dation of emerging technologies. The current issue is devoted to computer systems research and the application of such research, which naturally complement each other.

Each paper describes a detailed experiment or a case study of the methodology presented to amplify the impact of the contribution.

The denotational and expressive needs in cognitive informatics, computational intelligence, software engineering, and knowledge engineering have led to the development of new forms of mathematics collectively known as denotational mathematics. Denotational mathematics is a category of mathematical structures that formalize rigorous expressions and long-chain inferences of system compositions and behaviors with abstract concepts, complex relations, and dynamic processes. Typical paradigms of denotational mathematics are concept algebra, system algebra, Real-Time Process Algebra (RTPA), Visual Semantic Algebra (VSA), fuzzy logic, and rough sets. A wide range of applications of denotational mathematics have been identified in many modern science and engineering disciplines that deal with complex and intricate mathematical entities and structures beyond numbers, Boolean variables, and traditional sets. This issue of Springer's Transactions on Computational Science on Denotational Mathematics for Computational Intelligence presents a snapshot of current research on denotational mathematics and its engineering applications. The volume includes selected and extended papers from two international conferences, namely IEEE ICCI 2006 (on Cognitive Informatics) and RSKT 2006 (on Rough Sets and Knowledge Technology), as well as new contributions. The following four important areas in denotational mathem- ics and its applications are covered: Foundations and applications of denotational mathematics, focusing on: a) c- temporary denotational mathematics for computational intelligence; b) deno- tional mathematical laws of software; c) a comparative study of STOPA and RTPA; and d) a denotational mathematical model of abstract games.
