| dc.description.abstract | Security of public key cryptography is steadily threatened by advancements in algorithmics and computing power. In this work we propose a novel approach to long-term secure key exchange based on security assumptions that are independent of strong complexity assumptions. We present a key propagation scheme that sets up a network of distributed keys. Whenever two parties meet, they exchange new keys (e.g. using near field communication) and pass on all keys received so far. This establishes a dense key network growing and spreading with each meeting of protocol participants. Even two parties that have never met in person can use this network to obtain a common secret. A notable security feature of our scheme is the anonymity of the established keys, making it hard for an adversary to track movements of protocol participants. | en |
