Attacks are Protocols Too
In this paper we show how to simulate attacks on authentication protocols in a realistic environment. The attack on the Needham-Schroeder public key protocol found by Gavin Lowe i...

Identifying Malicious Peers Before It's Too Late: A Decentralized Secure Peer Sampling Service
Many unstructured peer to peer (P2P) systems rely on a Peer Sampling Service (PSS) that returns randomly sampled nodes from the population comprising the system. PSS protocols are...

Attacking Power Generators Using Unravelled Linearization: When Do We Output Too Much?
We look at iterated power generators si = se i−1 mod N for a random seed s0 ∈ ZN that in each iteration output a certain amount of bits. We show that heuristically an output of...

A survey of algebraic properties used in cryptographic protocols
Abstract: Cryptographic protocols are successfully analyzed using formal methods. However, formal approaches usually consider the encryption schemes as black boxes and assume that ...
