Abstract. We give a careful, fixed-size parameter analysis of a standard [1,4] way to form a pseudorandom generator by iterating a one-way function and then pseudo-random function...
We show how to securely realize any multi-party functionality in a way that preserves security under an a-priori bounded number of concurrent executions, regardless of the number ...
A number of researchers have proposed using digital marks to provide ownership identification for intellectual property. Many of these techniques share three specific weaknesses: ...
