Abstract
The master thesis work aims at measuring and improving the security in modern implementations of distributed hash tables (DHT). In a first step, several known attacks will be carried out against a DHT with a small number of members. The effects of these attacks will be assessed and vulnerabilities in the current implementation will be identified. With these vulnerabilities in mind, a security-enhancement with focus on authentication is to be designed and implemented in the DHT communication protocol. Furthermore, as the DHT may consist of computationally limited devices, optimizations to decrease load and limit the security-overhead will be evaluated. Lastly, this master thesis will investigate if the security enhancement could be implemented in a globally available DHT with millions of members. All simulations will be performed in the Ericsson-developed IoT environment "Calvin" which uses the Kademlia DHT.
