In this work, we design a method for creating public key broadcast encryption systems. Our main technical innovation is based on a new “two equation” technique for revoking us...
Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructur...
It is sometimes argued (as in [6]) that finding meaningful hash collisions might prove difficult. We show that at least one of the arguments involved is wrong, by showing that for...
— In recent times, many protocols have been proposed to provide security for various information and communication systems. Such protocols must be tested for their functional cor...
The GSM network with the greatest worldwide number of users, succumbs to several security vulnerabilities. The Short Message Service (SMS) is one of its superior and well-tried se...
