We propose a general multiparty computation protocol secure against an active adversary corrupting up to n−1 of the n players. The protocol may be used to compute securely arithm...
Abstract— An important issue in mobile commerce (mcommerce) is to exchange digital data between two distributed parties in an efficient and fair manner. In this paper, a lightwe...
Efficient key distribution is an important problem for secure group communications. The communication and storage complexity of multicast key distribution problem has been studied ...
The intent of peer data management systems (PDMS) is to share as much data as possible. However, in many applications leveraging sensitive data, users demand adequate mechanisms to...
Abstract.We introduce the notion of distributed password-based publickey cryptography, where a virtual high-entropy private key is implicitly dened as a concatenation of low-entrop...
