We show that every construction of one-time signature schemes from a random oracle achieves black-box security at most 2(1+o(1))q , where q is the total number of oracle queries a...
Concast is a customizable many-to-one network-layer communication service. Although programmable services like concast can improve the efficiency of group applications, accompanyi...

Couple to the communications wired and unwired networks growth, is the increasing demand for strong secure data transmission. New cryptographic standards are developed, and new en...
We present a new commerce protocol that allows customers and merchants to conduct face-to-face creditcard authorizations with a credit card company securely with the option of ano...
We propose a new public key trace and revoke scheme secure against adaptive chosen ciphertext attack. Our scheme is more efficient than the DF scheme suggested by Y. Dodis and N. F...
