Abstract. We consider the central cryptographic task of secure twoparty computation, where two parties wish to compute some function of their private inputs (each receiving possibl...
In this work, we consider Authentication and Key Agreement (AKA), a popular client-server Key Exchange (KE) protocol, commonly used in wireless standards (e.g., UMTS), and widely c...
The first and still most popular solution for secure two-party computation relies on Yao's garbled circuits. Unfortunately, Yao's construction provide security only again...
We explore the security of blind signatures under aborts where the user or the signer may stop the interactive signature issue protocol prematurely. Several works on blind signatur...
To support secure exchanging and sharing of XML data over the Internet, a myriad of XML access control mechanisms have been proposed. In the setting of node-level fine-grained acc...
