Social Engineering (SE) threats have constituted a reality for Information Technology (IT) systems for many years. Yet, even the latest editions of the generally accepted Information Security (IS) standards and best practices directives do not effectively address the Social Engineering aspect of IS defences. SE attacks target the human element of IS by exploiting human relations to the maximum ...

Various aspect-oriented languages, e.g., AspectJ, AspectWerkz, and JAsCo, have been proposed as extensions to one particular object-oriented base language, namely Java. But these extensions do not fully take the interactions with the Java 2 security model into account. In particular, the implementation technique of advice weaving gives rise to two security issues: the erroneous assignment of as...

Acquiring digital media over the Internet has become commonplace in recent years. Companies are looking into ways to sell their content (music, movies, etc.) over the Internet without the buyer being able to further distribute the work. Digital Rights Management (DRM) systems address this; their main goal is to enable authorised users to access a version of digital content on the terms for whic...

Sensor networks are amassed wireless networks of small, lowcost sensors that collect and propagate environmental data. The emerging field of wireless sensor networks integrates sensing, computation, and communication into a single device. The power of wireless sensor networks verifies in the capability to deploy huge numbers of small nodes that collaborates and configure them. Wireless sensor n...

• Joshua Guttman in “Establishing and preserving protocol security goals” proposes a model-theoretic approach to the verification of security properties, where the models are executions, and the security goals are implications over the geometric fragment of predicate logic. This methodology also leads to a new reading of protocol refinement and transformation, and offers the possibility of reas...

The story of vascular ageing was first described in the seventeenth century when Thomas Sydenham wrote that ‘A man is as old as his arteries’. This aphorism was returned to publicity lately when Peter Nilsson reintroduced the concept of early vascular ageing. As vascular ageing is described a gradual process involving biochemical, enzymatic, and cellular changes of the vasculature and modificat...

Abnormality of the placental vasculature affects placental thickness. Abstract. 31 Background. Our empirical modeling suggests that deformation of placental vascular growth is 32
