In [1], a scalable and small-bandwidth certificate validation scheme was presented. We call this system NOVOMODO, to emphasize the new way in which it approaches the field. In this paper, we recall the NOVOMODO technology and • Compare the efficiency and security of NOVOMODO and OCSP; and • Discuss how NOVOMODO may simplify PKI management in several applications (e.g., attribute certs). 1. Trad...

On the morning of July 1st 1916, after five days of intense bombardment, the British Fourth Army under General Sir Henry Rawlinson, with a ration strength of 519,324 men, supported by two divisions of the Third Army, under General Sir Edward Allenby, advanced into what was to be known hereafter as the first day of the Battle of the Somme. Within the first 60 minutes of that attack, those troops...

In a distributed system, using authorisation certificate based access control tends to facilitate the granting of rights. On the other hand, the problems of limiting usage or revoking the rights become more difficult, as the issuer of the right is no longer in control of the issued certificate. In this paper we take a look at the role of certificates in access control, evaluate the technical me...

Certificates carry signed statements within a PublicKey Infrastructure (PKI). As we begin to build more complex and more open PKIs, the limited expressiveness of current certificate languages becomes a concern. While certificates are traditionally treated as simple data structures conforming to a given schema, we show an alternative derivation of the concept of a certificate in which certificat...

Up to now, state-of-the-art industrial robots played the most important role in real-world applications and more advanced, highly sensorized robots were usually kept in lab environments and remained in a prototypical stadium. Various factors like low robustness and the lack of computing power were large hurdles in realizing robotic systems for highly demanding tasks in e.g. domestic environment...

Transmission of Corynebacterium insidiosum (McCull.) Jensen (cause of bacterial wilt in alfalfa) by the stem and bulb nematode Ditylenchus dipsaci (Kiihn) was demonstrated by Hawn (3) . Disease development in plants where D. dipsaci was the vector was comparable to that in the controls where wilt was induced by the root-ball soak method devised by Cormack, Peake and Downey (1) . Furthermore, th...

BACKGROUND In this study we estimated the presence of Legionella species, viable but non-culturable (VBNC), in hospital water networks. We also evaluated the time and load of Legionella appearance in samples found negative using the standard culture method. METHODS A total of 42 samples was obtained from the tap water of five hospital buildings. The samples were tested for Legionella by the s...

After crawling and keyword indexing, the next wave that has made a significant impact on Web search is topic distillation: analyzing properties of the hyperlink graph for enhanced ranking of Web pages in response to a query. Hyperlink induced topic search (HITS) and PageRank (used in Google) are two examples. The linear algebra involved in HITS and PageRank is standard, but selecting the releva...

Balloon valvuloplasty (BV) is currently the treatment of choice for pulmonic stenosis in humans and dogs. Before permission was obtained to attempt the 1st BV in a child in 1982, the safety and efficacy of the procedure were tested in 1980 in an English Bulldog with spontaneous pulmonic stenosis. A fatal outcome would have caused indefinite postponement of BV in human patients, a procedure that...
