C. Alcaraz, and J. Lopez, "WASAM: A Dynamic Wide-Area Situational Awareness Model for Critical Domains in Smart Grids",
Future Generation Computer Systems, vol. 30, Elsevier, pp. 146-154, 2014. DOI (I.F.: 2.786)More..


Control from anywhere and at anytime is nowadays a matter of paramount importance in critical systems. This is the case of the Smart Grid and its domains which should be monitored through intelligent and dynamic mechanisms able to anticipate, detect and respond before disruptions arise within the system. Given this fact and its importance for social welfare and the economy, a model for wide-area situational awareness is proposed in this paper. The model is based on a set of current technologies such as the wireless sensor networks, the ISA100.11a standard and cloud-computing together with a set of high-level functional services. These services include global and local support for prevention through a simple forecast scheme, detection of anomalies in the observation tasks, response to incidents, tests of accuracy and maintenance, as well as recovery of states and control in crisis situations.

J. Lopez, R. Oppliger, and G. Pernul, "Why Public Key Infrastructures have failed so far?",
Internet Research, vol. 15, no. 5, Emerald, pp. 544-556, 2005. (I.F.: 0.688)More..


Since public key cryptography is a fundamental technology for electronic commerce, people have often argued that public key infrastructures and corresponding certification services are the gold-mines of the information age. Contrary to these relatively high expectations, public key infrastructures have not really taken off and many certification service providers have even gone out of business. In this paper, we overview and discuss the technical, economical, legal, and social reasons why public key infrastructures have failed so far, summarize the lessons learnt, and give our expectations about the future development of the field.
