Secure Multiparty Computation (SMC) has gained tremendous importance with the growth of the Internet and E-commerce, where mutually untrusted parties need to jointly compute a fun...
We investigate several previously suggested scenarios of instantiating random oracles (ROs) with “realizable” primitives in cryptographic schemes. As candidates for such “in...
No reliable method currently exists to safeguard the privacy of private information. Privacy policies are insufficient as compliance can not be enforced automatically. In this pap...
Abstract. We present a new cryptographic auction protocol that prevents extraction of bid information despite any collusion of participants. This requirement is stronger than commo...
Motivated by the need to outsource file storage to untrusted clouds while still permitting limited use of that data by third parties, we present practical protocols by which a cli...
