Probabilistic Type-2 Operators and ``Almost''-Classes

We define and examine several probabilistic operators ranging over sets
(i.e., operators of type 2), among them the formerly studied
ALMOST-operator. We compare their power and prove that they all coincide
for a wide variety of classes. As a consequence, we characterize the
ALMOST-operator which ranges over infinite objects ... more >>>

Resource Bounded Immunity and Simplicity

Revisiting the thirty years-old notions of resource-bounded immunity and simplicity, we investigate the structural characteristics of various immunity notions: strong immunity, almost immunity, and hyperimmunity as well as their corresponding simplicity notions. We also study limited immunity and simplicity, called k-immunity and feasible k-immunity, and their simplicity notions. Finally, we ... more >>>

On the Communication Complexity of Key-Agreement Protocols

Revisions: 2

Key-agreement protocols whose security is proven in the random oracle model are an important alternative to the more common public-key based key-agreement protocols. In the random oracle model, the parties and the eavesdropper have access to a shared random function (an "oracle"), but they are limited in the number of ... more >>>
