Global Communication Guarantees in the Presence of Adversaries

Abstract

DDoS attacks have been plaguing the Internet for over 20 years. For every defense mechanism invented, attackers find a new way to circumvent it. Is it possible to fundamentally prevent DDoS attacks and achieve global communication guarantees? Since the Internet is a public resource, what does it even mean to prevent DDoS-since the adversary can also claim to be communicating "legitimately." In this talk we will unravel the different forms of DDoS attacks by first discussing how to construct meaningful definitions, and second showing how to achieve communication guarantees. This talk then demonstrates how global communication guarantees can be achieved in the SCION secure Internet architecture [1-3]. CCS CONCEPTS • Networks → Network design principles; Public Internet; • Security and privacy → Security protocols; Denial-of-service attacks.

Ways for Enhancing the Substance in Consumer-Targeted eHealth

“…The Internet is evolving at a fast rate in terms of applications and services, but the basics of core Internet protocols have remained the same, which means that the various security threats contained in the protocols stay the same (Perrig, 2020). The current security situation also means that options are required when designing digital service concepts for healthcare; there is no sense in insisting that health clients manage only digitally (Rissanen, 2021;Rissanen & Rissanen, 2021).…”

“…It is a general misunderstanding that there are no end-to-end networks other than IP, or that one cannot be built conveniently at a realistic price. (Kantola, 2020) Novel Internet architectures (e.g., SCION) have been used to solve recognized security matters, from route control to endto-end transmission (Perrig, 2020).…”
