Practical Techniques for Searches on Encrypted Data

1. A pseudorandom generator , i.e., a stream cipher. We say that dorandom generator if every algorithm is a -secure pseu-with run-ning time at most has advantage Adv . The advantage of an adversary is defined as Adv are random variables distributed uniformly, where on. 2. A pseudorandom function . We say that is a -secure pseudorandom function ................
