Garbled circuits provide a powerful tool for jointly evaluating functions while preserving the privacy of each user’s inputs. While recent research has made the use of this primitive more practical, such solutions generally ...

Mobile browsers are increasingly being relied upon to perform security sensitive operations. Like their desktop counterparts, these applications can enable SSL/TLS to provide strong security guarantees for communications ...

Garbled circuits offer a powerful primitive for computation on a user’s personal data while keeping that data private. Despite recent improvements, constructing and evaluating circuits of any useful size remains ...

The growth of smartphone capability has led to an explosion of new applications. Many of the most useful apps use context-sensitive data, such as GPS location or social network information. In these cases, users may not ...

Malware targeting mobile phones is being studied with increasing interest by the research community. While such attention has previously focused on viruses and worms, many of which use near-field communications in order ...

HTTP cookies are the de facto mechanism for session authentication in web applications. However, their inherent security weaknesses allow attacks against the integrity of web sessions. HTTPS is often recommended to protect ...

Context aware applications provide users with an increasingly rich set of services. From services such as interactive maps to restaurant guides and social networking tools, the use of information including location, ...

Mobile web browsers now provide nearly equivalent features when compared to their desktop counterparts. However, smaller screen size and optimized features for constrained hardware make the web experience on mobile browsers ...

Many web applications are vulnerable to session hijacking attacks due to the insecure use of cookies for session management. The most recommended defense against this threat is to completely replace HTTP with HTTPS. ...
