Remotely keyed encryption schemes (RKESs), introduced by Blaze 6], support high-bandwidth cryptographic applications (such as encrypted video conferences) in which long-lived secre...
Abstract. In this paper we present a method for improving the performance of RSA-type exponentiations. The scheme is based on the observation that replacing the exponent d by d = d...
Abstract. This paper introduces a cryptographic paradigm called selfescrowed encryption, a concept initiated by kleptography. In simple words, a self-escrowed public-key cryptosyst...
From von Solms and Naccache's standpoint, constructing a practical and secure e-money system implies a proper regulation of its privacy level. Furthermore, when the system ben...
The security of smart card based electronic cash have been receiving significant attention recently. However, there has been little systematic analysis or quantification of the imp...
