There are two well studied security notions for public key encryption schemes: security against passive adversaries and security against active adversaries. In this talk, we will discuss a new generic transformation that can upgrade the security of an encryption scheme from passive security to active security. For this transformation, we use a special family of pseudorandom generators (PRGs) called hinting PRGs.

I will first introduce these special PRGs, followed by an outline of our transformation. No crypto background will be assumed for this talk. Joint work with Brent Waters.
