Mobile OS Market Share

An interesting study by Kantar Worldpanel shows the trend of the market share of mobile operating systems starting in January 2012. Android is currently, without doubt, the most popular platform, thanks to the presence on the market of several inexpensive devices and at the same time with good performance.  Windows Phone, at least in Italy, although slightly down, has passed incredibly iOS, probably due to the different models of Nokia Lumia cheap Sponsored by telephone operators.  iOS is instead a slight decrease in spite of the interesting new features available with the iPhone 5s (see, for example, the biometric fingerprint recognition).  The data obtained by analyzing in more detail the study of Kantar WorldPanel allow you to better define the business model and the target of the app that you want to accomplish. For those who , like me, has as its core business t... [More]

Secure Element

A secure element (SE) is a tamper-resistant device capable of securely hosting applications and their confidential and cryptographic data (e.g. key management) in accordance with the rules and security requirements set forth by a set of well-identified trusted authorities. This presentation shows our solutions about Secure Element  

Silverlight PKCS#11 with JavaScript Interface

We worked a lot in the past months on NCryptoki, the .NET wrapper to PKCS#11 module and we worked a lot in finding the best way to integrate PKCS#11 tokens in a web page (aspx, php, jsp, etc.). Till now we used a Java based approach using a Java Applet embedded in the web page. Such an applet includes a Java version of NCryptoki (JCryptoki) and a JQuery script that supplies a JavaScript interface to JCryptoki's classes. Such a Java approach works as expected by has some not nice-to-have security issues that: 1) give a bad user experience; 2) are higly dependant on the JRE installed on the client side. So we searched for a better way. We ported the entire NCryptoki package to Silverlight 5 and we have created a Silverlight user control that exports the NCryptoki classes to the JavaScript world. This approach seems very nice respect to the user exeprience and doesn't give strong security i... [More]

Lettura della CNS con Silverlight

Una delle richieste più frequenti in quest'ultimo periodo è la disponibilità di un componente che consenta di leggere da pagina web (aspx, php, etc.) i dati contenuti nella CNS e di usare la CNS per autenticarsi in un sito web. La soluzione che ho proposto finora era basata su di un applet Java che inserita in una pagina web consente di accedere al contenuto della CNS (si veda: Cosa c'è nella mia CRS). Sebbene la soluzione funzioni bene, ha il difetto di mostrare all'utente un antipatico warning che avverte della presenza di un applet Java che potrebbe contenere codice maligno e danneggaire il computer. Ho quindi indagato sulla possibilità di sfruttare le potenzialità di Silverlight per realizzare un componente che sostituisse l'applet e con grande entusiasmo posso annunciare di aver realizzato uno User Control Silverlight che consente di acce...
